Micro-inserts are placed into the fallopian tubes by a catheter passed from the vagina through the cervix and uterus. The insert contains inner polyethylene terephthalate fibers to induce benign fibrotic reaction and is held in place by flexible stainless steel inner coil and a dynamic outer nickel titanium alloy coil (1). Once in place, the device is designed to elicit tissue growth (scarring) in and around the micro-insert to form over a period of three months an occlusion or blockage in the fallopian tubes; the tissue barrier formed prevents sperm from reaching an egg. Unlike other forms of tubal ligation, no general anaesthetic nor incision through the abdomen is required. Similar to some other methods of birth control, initially additional forms of birth control must be continued to prevent pregnancy until the method’s effectiveness can be confirmed.
What To Expect:
For the Essure method, three months after insertion a physician performs a special type of x-ray test called a hysterosalpingogram to confirm that the fallopian tubes are completely blocked and the patient can rely on the Essure micro-inserts for birth control.
What is Essure Sterilization?
Essure is a permanent transcervical sterilization procedure for women developed by Conceptus Inc. It was approved for use in the United States on November 4, 2002. It has been described as less expensive than laparoscopic bilateral tubal ligation.
Perforation, expulsion, or other unsatisfactory location of the micro-insert
Pregnancy and increased risk of ectopic pregnancy
Pain, cramping, vaginal bleeding, menstrual pattern changes, light periods at first then longer, heavier periods lasting up to 6–8 weeks
Nausea/vomiting, or fainting
