Staple-Free Compression Anastomosis

New staple-free anastomosis devices are based on a nickel titanium alloy with thermal-shape memory and use the body's natural healing process to reconnect two hollow, tubular organs such as the colon or intestines.

The new devices enable a surgeon to create a continuous almost seamless seal without the need for permanently embedded objects such as staples. As a result, the inner channel of the intestine is able to regain its natural tubular size and flexibility. The devices are biocompatible, are undetectable by magnetic resonance imaging (MRI), and are opaque to x-rays. They are also more stable and less subject to corrosion than materials such as stainless steel.

This new line of anastomosis devices was developed by Niti Medical Technologies (Netanya, Israel). The line has been cleared by the U.S. Food and Drug Administration (FDA). The company's devices can be used to perform side-to-side, end-to-side, and end-to-end compression anastomosis in open, laparoscopic, and hand-assisted surgery.

The line comprises the compression anastomosis clip (CAC), which securely clamps together side-to-side intestine; the compression anastomosis ring (CAR), designed to create end-to-end and end-to-side anastomoses throughout the gastronintestinal tract; and a stapling tissue closure (STC) device called Hand STC, a one-hand operation that enables accurate positioning, cutting, and repositioning at any stage of the stapling process.
