______________________________________________________________________________ Instructions For Use
This product is intended to prevent pregnancy. It does not protect against HIV infection and other sexually transmitted diseases.
Caution: Federal law restricts this device to sale by or on the order of a physician with appropriate training and experience.
Do not attempt to use the Essure Permanent Birth Control System before completely reading and understanding the information contained in this Instructions for Use and the Physician Training Manual.
I. DEVICE DESCRIPTION
The Essure Permanent Birth Control System is designed to provide a non-incisional alternative to women seeking permanent contraception. Using a transcervical approach, one Essure Micro-insert is placed in the proximal section of each fallopian tube lumen. When the Essure Micro-insert expands upon release, it acutely anchors itself in the fallopian tube. Subsequently, the Essure Micro-insert elicits an intended benign occlusive tissue response, resulting in tissue in-growth into the device that permanently anchors the device and occludes the fallopian tube, resulting in permanent contraception.
The Essure Permanent Birth Control System is comprised of the Essure Micro-insert, a disposable delivery system, and a disposable Split Introducer.
The Essure Micro-insert is a dynamically expanding Micro-coil that consists of a stainless steel inner coil, a Nickel Titanium (nitinol) expanding, superelastic outer coil, and polyethelene (PET) fibers. The PET fibers are wound in and around the inner coil. The Micro-insert, shown in Figure 1 below, is 4 cm in length and 0.8mm in diameter in its wound down configuration. When released from the delivery system, the outer coil expands to 1.5 to 2.0 mm in diameter to anchor the Micro-insert in the varied diameters and shapes of the fallopian tube.
Essure Micro-insert (Shown in its Expanded Configuration)
The disposable delivery system, shown is Figure 2 below, consists of a delivery wire, a release catheter, a delivery catheter and a delivery handle.
Essure Delivery System
NOTE: The delivery wire and the release catheter are not visible in the figure shown above.
The Essure Micro-insert is provided attached to the delivery wire, in a wound-down (low profile) configuration. The delivery wire is composed of a nitinol core wire, which is ground at the distal end to result in a flexible, tapered profile. The device is constrained by the release catheter which is sheathed by a flexible delivery catheter. A positioning bump on the tubing aids in proper placement of the device in the fallopian tube.
The delivery handle controls the device delivery and release mechanism. The thumbwheel on the delivery handle retracts both the delivery catheter and the release catheter. The button allows the physician to change the function of the thumbwheel from retracting the delivery catheter to retracting the release catheter. The delivery wire is detached from the Micro-insert by rotating the system.
The Split Introducer is intended to help protect the Essure Micro-insert as it is being passed through the rubber port of the hysteroscope working channel.
II. INDICATIONS FOR USE
The Essure System is indicated for permanent birth control (female sterilization) by occlusion of the fallopian tubes.
The Essure Permanent Birth Control System should not be used in any patient who is:
Uncertain about her desire to end fertility.
Currently taking systemic corticosteroids.
Or any patient with any of the following conditions:
Pregnancy or suspected pregnancy.
Delivery or termination of a second trimester pregnancy less than 6 weeks before Essure Micro-insert placement.
Active or recent pelvic infection.
Untreated acute cervicitis.
Gynecological malignancy (suspected or known).
Known abnormal uterine cavity or fallopian tubes that would make visualization of the tubal ostia and/or cannulation of the proximal fallopian tube difficult or impossible.
Known allergy to contrast media.
Known hypersensitivity to nickel confirmed by skin test.
Whenever possible, Micro-insert placement should be performed during days 7-14 of the menstrual cycle (where day 1 represents the first day of bleeding) in order to (a) decrease the potential for Micro-insert placement in a patient with an undiagnosed (luteal phase) pregnancy and (b) enhance visualization of the fallopian tube ostia.
In order to reduce the risk of uterine perforation, the procedure should be terminated if excessive force is required to achieve cervical dilatation.
When introducing the Essure Micro-insert into the fallopian tube, never advance the Micro-insert(s) against excessive resistance.
If tubal or uterine perforation occurs or is suspected, immediately discontinue the Essure placement procedure.
Do not continue to advance the Essure System once the positioning bump on the catheter has reached the tubal ostium. Advancement beyond this point could result in unsatisfactory Micro-insert placement and/or tubal/uterine perforation.
Once the Micro-insert has been placed, Micro-insert removal should not be attempted hysteroscopically, unless 18 or more coils of the Essure Micro-insert are trailing into the uterine cavity. Removal of such a Micro-insert should be attempted immediately following the placement; however, removal may not be possible.
The patient cannot rely on the Essure Micro-inserts for contraception and must use alternative contraception until an x-ray performed three months post-Micro-insert placement demonstrates satisfactory Micro-insert location.
Following placement of the Essure Micro-inserts, it is recommended that electrocautery be avoided in surgical procedures undertaken on the uterine cornua and fallopian tubes. In other procedures in the pelvis, avoid the use of electrocautery within 4 cm of the Micro-insert. Due to the presence of the Essure Micro-inserts, there may be risks associated with such procedures that, at this time, have not been identified.
Any intrauterine procedure performed following the Essure procedure could interrupt the ability of the Essure Micro-inserts to prevent pregnancy. In addition, the presence of the Essure Micro-inserts could involve risks associated with such procedures that, at this time, have not been identified.
There are no data on the safety or effectiveness of surgery to reverse the Essure procedure.
Patients may decide, in future years, to undergo in vitro fertilization (IVF) to become pregnant. The effects of the Essure Micro-inserts on the success of IVF are unknown. If pregnancy is achieved, the risks of the Micro-insert to the patient, to the fetus and to the continuation of a pregnancy are also unknown.
Do not use the Essure System if the sterile package is open or damaged. Do not use if the Micro-insert is damaged.
Testing to ensure safety and compatibility with Magnetic Resonance Imaging (MRI) has been conducted using a 1.5 Tesla magnet. The Essure Micro-inserts were found to be MR safe at this field strength. However, the presence of the Micro-inserts produces an MR artifact which will obscure imaging of local tissue.
Unusual uterine anatomy may make it difficult to place the Essure Micro-inserts.
If Essure Micro-insert placement attempts are not successful after 10 minutes of attempted cannulation per tube, the case should be terminated and potentially rescheduled.
Both tubal ostia should be identified and assessed hysteroscopically prior to proceeding to Essure Micro-insert placement. No attempt should be made to place a Micro-insert in one tubal ostium unless there is a reasonable expectation that the opposite tube is accessible and patent.
Do not advance the Essure System if the patient is experiencing extraordinary pain or discomfort.
For single use only. Never attempt to resterilize an Essure Micro-insert or delivery system.
When removing the metal obturator from the introducer, there is a possibility that saline will be washed back through the operating channel of the hysteroscope. Proper eye and face protection should be utilized.
The Split Introducer must be used in order to avoid damage to the device tip.
The Split Introducer should be removed after the Micro-insert is introduced into the working channel. The working channel stopcock must remain in the open position to avoid damage to the Micro-insert or to the introducer.

Conceptus has conducted two clinical trials (a Phase II Trial and a Pivotal Trial) to demonstrate the safety and effectiveness of the Essure Permanent Birth Control System in providing permanent contraception. Results of these trials were reported in the premarket approval application (PMA) that supported market approval for the Essure product. Details of these clinical trials are presented below.
A. Purpose of the Study, Study Design, Primary Endpoints
The purpose of both studies was to evaluate the safety and effectiveness of the Essure Permanent Birth Control System in providing permanent contraception.
The Phase II study was a prospective, multi-center, international study of women seeking permanent contraception. The objectives of the study were to evaluate:
· The woman's tolerance of, and recovery from, the Micro-insert placement procedure;
· The safety of the Micro-insert placement procedure;
· The woman's tolerance of the implanted Micro-inserts;
· The long-term safety and stability of the implanted Micro-inserts; and
· The effectiveness of the Micro-inserts in preventing pregnancy.
The Pivotal study was a prospective, multi-center international study of women seeking permanent contraception. The study used findings from the U.S. Collaborative Review of Sterilization (CREST1 study) as a qualitative benchmark. The primary endpoints for the study included:
· Prevention of pregnancy;
· Safety of device placement procedure, and;
· Safety of device wearing.
The secondary endpoints for the study included:
· Participant satisfaction with device placement procedure;
· Participant satisfaction with device wearing;
· Bilateral device placement rate, and;
· Development of a profile for an appropriate candidate for the Essure procedure.
B. Patients Studied
The study population of the two studies combined consisted of 664 women in whom bilateral device placement was achieved. All study participants were between 21 and 45 years of age and were seeking permanent contraception prior to enrollment in the study. Additionally, all women had at least one live birth, had regular, cyclical menses and were able and willing to use alternative contraception for the first three months following Essure device placement.
All study participants were screened for eligibility to participate in the clinical study. A complete medical history was obtained. A physical examination, a pelvic examination and required laboratory tests (including a pregnancy test) were conducted.
An Essure device placement procedure was attempted on each fallopian tube. In the Pivotal Trial, a pelvic x-ray was performed within 24 hours following device placement to serve as a baseline evaluation of device location. Participants were instructed to use either a barrier contraceptive method or oral contraceptives for the first 3 months following the device placement procedure.
A hysterosalpingogram (HSG) was performed three months post device placement to evaluate device location and fallopian tube occlusion. If both fallopian tubes were occluded and both devices were satisfactorily placed within the fallopian tubes, the participant was instructed to discontinue use of alternative contraception and use only the Essure devices for prevention of pregnancy.
Of the 643 women enrolled in the clinical trials (with bilateral Micro-insert placement) and who relied on the Essure Permanent Birth Control System for contraception, no (zero) pregnancies were reported2. Adverse events that were reported in the clinical study are provided in Section VI., C above, and events by study are provided below.
Table 2 presents the principal safety and effectiveness results.

VIII. INDIVIDUALIZATION OF TREATMENT
The Essure Permanent Birth Control System is available in one size only. The risks and benefits previously described in Section VII - CLINICAL STUDIES should be carefully considered for each patient before use of the Essure Permanent Birth Control System. Patient selection factors to be assessed should include:
Patient's certainty about her desire to end fertility,
Gynecological co-morbidities (e.g., pelvic infection, cervicitis, vaginal bleeding), and
Patient's morphologic suitability for transcervical delivery/placement of Micro-inserts.
The final treatment decision is at the discretion of the patient.
A. Use in Specific Populations
The safety and effectiveness of the Essure Permanent Birth Control System has not been established in patients with any of the following characteristics:
Patients less than 21years old or greater than 45 years old
Patients who delivered a baby or terminated a second trimester pregnancy less than 6 weeks before Essure Micro-insert placement.
IX. PATIENT COUNSELING INFORMATION IMPORTANT: Patients should be counseled that this product is intended to prevent pregnancy. It does not protect against HIV infection and other sexually transmitted diseases. The physician should consider the following points when counseling the patient about this device:
Details contained in the Patient Information Booklet regarding risks associated with placement of the Essure Micro-inserts.
The procedure is permanent, and there are no data on the safety and effectiveness of a reversal procedure.
There is a mandatory waiting period of at least 3 months after the procedure before the doctor can advise the patient whether the Essure Micro-insert can be relied upon for permanent birth control.
Like all methods of birth control, the Essure procedure should not be considered 100% effective.
Conceptus recommends that the physician disclose to the patient (in written form) all risks associated with treatment using the Essure Permanent Birth Control System, that the Essure procedure is permanent, and that there are no data on the safety or effectiveness of a reversal procedure. Please also refer to the Patient Counseling section of the Technical Bulletin from the American College of Obstetricians and Gynecologists (ACOG) regarding female sterilization.

XI. PHYSICIAN TRAINING MANUAL
The Essure Permanent Birth Control System Physician Training Manual contains detailed information not included in this Instructions for Use. Refer to the Physician Training Manual for additional information as required.
XII. DIRECTIONS FOR USE A. Prior to Micro-insert Placement Procedure
Micro-insert placement should be performed during days 7-14 of the menstrual cycle (where day 1 represents the first day of bleeding) in order to (a) decrease the potential for Micro-insert placement in a patient with an undiagnosed pregnancy and (b) enhance visualization of the fallopian tube ostia.
A pregnancy test administered by the physician or designee, should be conducted within 24 hours prior to or immediately preceding the Micro-insert placement procedure.
Administration of a non-steroidal anti-inflammatory drug (NSAID) such as diclofenac (Cataflam/Voltaren) or ketorolac (orally or via I.M. injection) is recommended one to two hours before the Micro-insert placement procedure. If using only a paracervical block, diazepam (PO), or a similar agent, may also be offered 30 minutes prior to the procedure to reduce anxiety.
B. Micro-insert Placement Procedure The Essure Micro-insert placement procedure can be performed in an outpatient or office surgery setting. Sterile technique should be used during the Micro-insert placement procedure following universal precautions. The amount of time required to complete the Micro-insert placement procedure should not exceed 30 minutes.
1. Place the patient in the lithotomy position.
2. Introduce a speculum into the vagina to allow access to the cervix. Prep the cervix with betadine or other suitable antibacterial solution according to standard practice.
3. Local anesthesia is the preferred method for implantation of the Micro-inserts. A paracervical block may be administered. Midazolam (IV), or a similar agent, may also be administered to prevent or reduce discomfort if needed.
4. Insert a sterile hysteroscope, with attached camera and operating channel ( 5 French), through the cervix into the uterine cavity. Do not perform cervical dilation unless necessary to allow hysteroscope insertion. In order to prevent uterine perforation, the procedure should be terminated if excessive force is required to achieve cervical dilatation.
5. Uterine cavity distention should be accomplished with a physiologic saline infusion through the inflow channel of the hysteroscope. It is strongly recommended that the saline solution be pre warmed to body temperature and introduced under gravity feed to minimize spasm of the fallopian tubes. Adequate uterine distention must be achieved and maintained throughout the procedure in order to allow identification of and access to the fallopian tube ostia. Standard fluid monitoring procedures should be followed throughout the procedure.
6. Both tubal ostia should be identified and assessed hysteroscopically prior to proceeding to Essure Micro-insert placement. No attempt should be made to place a Micro-insert in one tubal ostium unless there is a reasonable expectation that the opposite tube is patent.
7. Once the fallopian tube ostia have been identified, insert the Split Introducer through the rubber port on the hysteroscope working channel. The operating channel stopcock should remain in the open position (the device and/or introducer can be damaged if the stopcock closes on either device). Place the Essure delivery system through the introducer and advance through the operating channel of the hysteroscope.
Insert Split Introducer and Essure Micro-insert through
rubber port on hysteroscope working channel
8. Advance the Essure delivery system into the proximal fallopian tube with slow, steady forward movement to prevent tubal spasm. Advance the delivery system until the positioning bump on the delivery catheter reaches the fallopian tube ostium. This visual marker indicates that the Essure Micro-insert is spanning the intramural and the proximal isthmic segments of the fallopian tube, with the outer coil spanning the uterotubal junction. This is the ideal placement for the Essure Micro-insert.
Advance until positioning bump at tubal ostium.
This is visual indicator for proper position for deployment.
9. Proper concentric alignment of the delivery catheter with the tubal lumen is suggested by the ability to advance the catheter under direct visualization without undue resistance. Resistance to advancement is usually apparent if: 1) the black marker on the outside surface of the catheter is seen not to advance forward towards the tubal ostium, and/or 2) the delivery catheter bends or flexes excessively, thus preventing the physician from applying forward pressure on the catheter assembly. When such resistance to forward advancement of the catheter is observed, no further attempts should be made to place the Micro-insert in order to avoid the possibility of uterine perforation or inadvertently placing the Micro-insert in the uterine musculature rather than within the tubal lumen. A follow-up HSG should be undertaken to determine tubal patency.
10. If it is not possible to advance the catheter to the positioning bump after several minutes, a perfusion test with a patency catheter may be employed, if it has not already been utilized, to determine tubal patency. If the tube is blocked or the catheter cannot be advanced to the positioning bump, the case should be terminated. If Micro-insert placement is not successful after 10 minutes of attempted cannulation per tube, the case should be terminated.
11. Only after the delivery catheter has been advanced to the positioning bump should the Micro-insert be deployed. To do so, first stabilize the handle of the Essure Micro-insert against the hysteroscope or camera to prevent inadvertent forward movement of the Essure System during retraction of the delivery catheter.
Stabilize Handle Against Camera Head or Some
Other Fixed Object to Prevent Inadvertent
Forward Movement of the Essure System
12. Being certain that the positioning bump is at the fallopian tube ostium, rotate the thumb-wheel on the handle towards the operator. This should be accomplished no faster than 1 click per second until the wheel no longer rotates. This facilitates withdrawal of the delivery catheter. The black positioning bump will be seen to move away from the tubal ostium (towards the hysteroscope) and disappear into the operating channel. Withdrawal of the delivery catheter exposes the wound-down Essure Micro-insert attached to the release catheter. Approximately 1cm of the Micro-insert (wound-down coils) should appear trailing into the uterus when the delivery catheter is withdrawn. If more is visible, the Micro-insert should be repositioned, if possible, before proceeding to step #13.
Rotate Thumbwheel to Retract Catheter
13. After retracting the delivery catheter, depress the button on the handle to enable the thumb-wheel to be further rotated. Rotate the thumb-wheel towards the operator to withdraw the release catheter. When the thumb-wheel cannot be rotated any further, release catheter withdrawal is complete. Withdrawal of the release catheter enables the outer coil of the Essure Micro-insert to expand. The operator should see the outer coils expand. If expansion is not observed, gently move the delivery wire away from the uterine wall to release pressure on the outer coil.
After Complete Retraction of Catheter,
Press Button to Enable Thumbwheel to Rotate Again
14. Wait approximately 10 seconds to allow the outer coils to fully expand. Once the outer coils are expanded, rotate the entire handle counter-clockwise at least 10 rotations. Continue to rotate while gently pulling backwards on the handle to release the delivery wire from the Essure Micro-insert. The delivery system will then be withdrawn through the working channel of the hysteroscope.
Rotate Handle Counter-Clockwise to Detach
Delivery Wire from Micro-insert
15. Once the delivery system has been withdrawn, the position of the Essure Micro-insert should be assessed. There should ideally be 3 to 8 expanded outer coils of the Essure Micro-insert trailing into the uterus.
Expanded Outer Coils of the Essure Micro-insert Trailing
Into the Uterus Indicates Ideal Placement
16. Unless the Micro-insert has a trailing length that is greater than 18 expanded outer coils, the Micro-insert should be left in place and evaluated via pelvic x-ray three months post device placement.
WARNING: Micro-insert removal should not be attempted hysteroscopically once the Micro-insert has been placed, unless 18 or more coils of the Essure Micro-insert are trailing into the uterine cavity. Attempted removal of a Micro-insert having less than 18 or more coils trailing into the uterine cavity may result in fallopian tube perforation or other patient injury. IMPORTANT: If the Micro-insert was inadvertently deployed in the uterine cavity and not into the tube, then the Micro-insert should be removed from the uterus and another attempt made at Micro-insert placement in the tube.
17. If there are 18 or more expanded outer coils are trailing into the uterus, then the Micro-insert should be immediately removed from the uterus (as described in steps 1-5) and another attempt made at Micro-insert placement in the tube. Micro-insert removal may not always be possible. 1 - As necessary, administer analgesia/anesthesia to reduce or prevent patient discomfort.
2 - Introduce a grasping instrument through the hysteroscope working channel.
3 - Grasp the outer coil of the Essure Micro-insert. Try to grasp the outer and inner coil of the Micro-insert together.
4 - Slowly pull back on the grasping instrument and withdraw the hysteroscope at the same time, so that the entire system is removed from the uterus.
5 - The outer coil and/or the inner coil of the Essure Micro-insert may stretch or elongate as Micro-insert removal is being attempted.
If complete Micro-insert removal is accomplished, an attempt should be made to place another Essure Micro-insert. If the physician is not completely satisfied that the entire Essure Micro-insert has been removed from the fallopian tube, another Micro-insert should NOT be placed in that tube and a post-placement x-ray should be taken to determine if a Micro-insert fragment remains in vivo.
18. Record the length of the Micro-insert trailing into the uterine cavity, noting any issues with identifying or confirming either tubal ostium or any concern regarding potential perforation. These should be noted in patient records for subsequent reference when reviewing the 3-month x-ray (See Section C below). Additionally, the following information should be noted in the patient records:
Concern, at the time of device placement, of possible perforation due to excessive force required on the delivery catheter, a sudden loss of resistance, or a trailing length of less than 0 mm, as seen hysteroscopically after device placement.
The visible trailing length of the micro insert at the conclusion of device placement if less than 3 mm or greater than 10 mm.
Identification of the tubal ostium, at the device placement procedure, was compromised due to poor distention, poor illumination or poor visualization, secondary to endometrial debris.
19. Repeat the Essure Micro-insert placement procedure in the contralateral fallopian tube.
C. Patient Follow-up Requirements
Patients should be scheduled for a pelvic x-ray, 3 months following the Essure micro insert placement procedure for the purpose of evaluating Micro-insert retention and location. Ideally, the x-ray should be performed at a time so as to allow the physician appropriate time to evaluate the x-ray and discuss the findings with the patient. Precise and correct evaluation of the pelvic x-ray is critical to the physician’s decision as to whether or not it is appropriate for his or her patient to discontinue alternative contraception.
X-rays will be interpreted as either satisfactory, suspicious, or unsatisfactory.
A satisfactory x-ray is one in which the micro inserts appear to be in the tubal lumen and spanning the uteral tubal junction and appear relatively symmetrical. Patients whose x-rays are determined to be satisfactory, may be told to rely on the Essure micro insert for contraception and to discontinue alternative contraception.
An x-ray that is deemed to be suspicious is one in which one or both of the Micro-inserts appear to be distal, or proximal, to what would be an ideal position in the fallopian tube. Alternatively, a suspicious x-ray may be one in which one or more of the devices appear to have completely perforated the uterine tube and myometrium, so as to appear relatively asymmetrical. Patients whose x-rays are determined to be suspicious should be instructed to continue alternative contraception, and to undergo an HSG so as to evaluate tubal patency.
An x-ray that is deemed to be unsatisfactory is one in which there is obvious intra-peritoneal location of one or more Micro-inserts, or where there is clear evidence of expulsion of one or more of the Micro-inserts. Patients whose x-rays are deemed to be unsatisfactory, should be instructed to continue alternative contraception. Patients who wish to be considered for re-attempt at placement of the Essure device, should undergo an HSG, so as to evaluate tubal patency and then be managed according to the instructions in the Physician Training Manual for management of patients with unsatisfactory Micro-insert location.
The following issues (related to the device placement procedure, and patient symptoms for the 3-months since device placement), should be considered in interpreting the pelvic x-rays. These include:
Concern, at the time of device placement, of possible perforation due to excessive force required on the delivery catheter, a sudden loss of resistance, or a trailing length of less than 0 mm, as seen hysteroscopically after device placement.
The visible trailing length of the micro insert at the conclusion of device placement is either less than 3 mm or greater than 10 mm.
Identification of the tubal ostium, at the device placement procedure, was compromised due to poor distention, poor illumination or poor visualization, secondary to endometrial debris. Such situations might not only affect the ability to correctly place the micro inserts, but might also adversely affect the ability to evaluate the trailing length of the device.
The patient has complained of consistent uterine cramping, and/or bleeding/spotting since the performance of the procedure.
ALL PATIENTS WITH SUSPICIOUS OR UNSATISFACTORY X-RAYS MUST BE ADVISED TO CONTINUE ALTERNATIVE CONTRACEPTION, UNTIL PERFORMANCE OF HSG TO EVALUATE EVIDENCE OF TUBAL PATENCY OR OCCLUSION.
D. Micro-insert Removal
Once the Micro-insert placement procedure is concluded, Micro-insert removal should only be attempted if a patient is experiencing an adverse event(s) related to the Micro-insert or if she demands Micro-insert removal. Such removal should not be attempted hysteroscopically and will likely require a cornual resection if the Micro-insert is across the utero-tubal junction.
IMPORTANT: Hysteroscopic attempts to remove the Micro-insert should only be performed during the Micro-insert placement procedure.
Detailed recommendations for Micro-insert removal are contained in the Physician Training Manual.
