ESSURE MICRO-INSERT COIL DEVICE
A DETAILED EXPLANATION
Essure is designed to cause permanent blockage of the fallopian tubes. This blockage is not immediate but happens slowly over time. During the Essure procedure, the doctor inserts a single Essure micro-insert device into the opening of each fallopian tube.
Each Essure device is a pair of coils. The outer coil expands and anchors the coil into the fallopian tube. The inner coil contains fibers, which promote scar tissue formation. The formation of scar tissue within the tube is what causes the tube to heal with scar tissue and become permanently blocked.
The larger, wider outer coil is an expanding coil made from a nickel titanium alloy, otherwise known as nitinol. The purpose of the outer coil is to expand after insertion and to firmly anchor the device into the fallopian tube.
The smaller inner coil is made of stainless steel. Wrapped around this inner coil are polyethelene (PET) fibers. The PET fibers acts as an irritant and cause the ingrowth of scar tissue, which will firmly anchor the entire system in place and cause permanent blockage of the fallopian tube.
The outer coil is designed to both remain in position inside the fallopian tube and hold the inner coil in place. The inner coil is designed to hold the PET fibers in place and the PET fibers are intended to promote scar tissue formation. Once the scar tissue has formed then the fallopian tube will be permanently blocked.
