Essure is a permanent Birth Control System. Each Essure Kit is comprised of two pouched disposable delivery systems with a wound-down insert and a valved introducer.
A small, sterile, implantable device that is implanted into the uterine end of the fallopian tubes (one device in each tube) to functions as a contraceptive through the obstruction of the natural fallopian tube passage. It typically consists of a micro insert with a stainless steel inner coil, a nickel-titanium alloy (Nitinol) "elastic" outer coil, and polyethylene (PE) fibres loaded into a delivery device. Upon placement and delivery, during a hysteroscopy, the device expands and anchors to the varied diameters and shapes of the fallopian tube and results in tubal occlusion by the PE fibres eliciting a tissue in-growth, this preventing the passage of ova.
