Shape memory polymers boost implant performance


Medshape (Atlanta, GA) reports commercialization of the first FDA-cleared medical device made with shape memory polymers.

Using Solvay's Zeniva PEEK as a base material, MedShape developed a proprietary shape memory PEEK alloy called Altera which allows devices to enter the target surgical site in a compact geometry and then be triggered to deploy with minimal mechanical force into the optimal geometry for fixation.

The specific products are called the Morphix Suture Anchor for tendon and ligament repair and the ExoShape Soft Tissue Fastener for knee joint ACL reconstruction.

MedShape says it is the only company to have developed and introduced FDA-cleared devices manufactured from shape memory polymers based on PEEK (polyetheretherketone) and PMMA (polymethylmethacrylate) chemistries....
