About the Essure Procedure

The Essure procedure, approved by the FDA in 2002, is a sterilization procedure that replaces tubal ligation for women. A soft micro-insert is placed into the Fallopian tubes through the cervix using a hysteroscope. Once in place, the device is designed to elicit tissue growth in and around the micro-insert to form an occlusion or blockage in the Fallopian tubes, over three months. An Essure procedure does not require cutting into the body and can be performed in the doctor’s office, a less costly procedure setting, with just a local anesthetic. A woman is able to leave the office about 45 minutes after the procedure is completed. The Essure confirmation test is performed three months after the procedure to confirm that the micro-inserts are in the correct location, the tubes are blocked and that the woman can discontinue temporary birth control. The Essure procedure is 99.80% effective (based on four years of clinical study follow-up data). The probability of pregnancy in 1000 women at 4 years is only 2.0 as compared to 11.8 for surgical tubal ligation procedures studied in CREST.
