About the Essure Procedure

The Essure procedure, approved by the FDA in 2002, is a permanent birth control procedure that replaces tubal ligation for women. In the comfort of a physician’s office and in about 10 minutes, the soft micro-inserts are placed into the Fallopian tubes through the cervix eliminating the need for incisions. 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. 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 with four years of data and is the first and only FDA approved female sterilization procedure to have zero pregnancies in clinical trials.
