Components The Essure permanent birth control system consists of two Essure micro-inserts, one insert per disposable delivery catheter, and two disposable introducers.
A standard hysteroscope with a 5 French working channel, continuous flow, and a 12-30 degree angled lens is used in concert with the Essure system.
The Micro-insertThe Essure micro-insert consists of a stainless steel inner coil, a nitinol, super-elastic outer coil, and polyethylene (PET) fibers. The PET fibers are wound in and around the inner coil. The micro-insert is 3.85 cm in length and 0.8 mm in diameter in its wound down configuration. When released, the outer coil expands to 1.5 to 2.0 mm to anchor the micro-insert in the varied diameters and contours of the fallopian tube.

Disposable Delivery SystemThe disposable delivery device consists of a single-handed ergonomic handle, which contains a delivery wire, release catheter, and delivery catheter housing the Essure micro-insert.
The ergonomic handle controls delivery and release. A button-thumbwheel combination on the handle allows for deployment of the micro-insert into the fallopian tube.
Introducer
The disposable introducer helps protect the micro-insert and prevent splash-back as it passes through the hysteroscope working channel.
