The Essure procedure, FDA approved since 2002 and CE Mark approved since 2001, is the first
permanent birth control method that can be performed in the comfort of a physician's office
without hormones, cutting, burning or the risks associated with general anesthesia or tubal
ligation. Soft, flexible inserts are placed in a woman's fallopian tubes through the cervix
without incisions. Over the next three months, the body forms a natural barrier around the
micro-inserts to prevent sperm from reaching the egg. Three months after the Essure
procedure, a doctor performs an Essure Confirmation Test. In the United States, this test is
called a hysterosalpingogram and evaluates the location of the inserts and whether the
fallopian tubes are blocked. Outside of the United States, a standard x-ray is performed to
evaluate the location of the inserts.
The purpose of this study is to evaluate whether a transvaginal ultrasound is an effective
method of confirming micro-insert location.
