About the Essure Procedure
The Essure procedure deploys a soft micro-insert into the fallopian tube through the cervix using a minimally invasive transcervical tubal access catheter. 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 tube. An Essure procedure does not require cutting or penetrating the abdomen and can be performed in a less costly procedure setting without general anesthesia. A woman is able to return home about 45 minutes after the procedure is completed. There is a three-month waiting period after the procedure during which women must use another form of birth control. The Essure procedure is 99.80 percent effective after four years of follow-up. The Essure procedure has been demonstrated in a small portion of the women undergoing clinical studies to be 99.74 percent effective based on five years of follow-up. Five-year follow-up of all patients in clinical trials is ongoing.
