According to Conceptus, the manufacturer of the Essure system, Essure is currently the most effective method of permanent birth control, with a failure rate resulting in pregnancy in less than one per 100 women. The Essure system is two micro-inserts inserted into the fallopian tubes. The micro-inserts, or coils made from materials widely used in medical devices, cause scar tissue to form around them over the three months following the procedure, which ultimately blocks the passage of the eggs from the ovary to the uterus. Routinely performed in a physician's office, Essure promises few to zero side effects; however, there are some side effects that may continue one year or more past the date of the procedure.
Pain
Because the Essure system is passed through the vagina, cervix and uterus to the fallopian tubes via a thin tube, no cutting or burning of the fallopian tubes is necessary, reducing potential procedural and post-procedural pain. However, some Essure clinical trial participants reported back, abdominal and urinary pain 15 months post-procedure, which was attributed to the micro-inserts.
Electrosurgical and Radio Frequency Injury
Essure indicates the micro-inserts can conduct energy if in close proximity to active electrosurgical devices. Direct micro-insert contact with radio frequencies may also damage nearby tissues. Women should inform healthcare providers of the implanted Essure system to avoid unnecessary tissue damage caused by electrosurgical and radio frequency devices.
Allergic Reaction
Allergic reaction to the nickel-plated micro-inserts is a possible side effect for some women. A nickel allergy is detectable by a simple skin test before the procedure. Women with known allergies to nickel should avoid the Essure sterilization system.
