Polyurethanes in medical devices.

Abstract

Because of their biocompatible qualities, polyurethanes have found many uses in the medical device field. This article describes several of the better-known polyurethanes and discusses their suitability for use in medical applications such as artificial heart systems, catheters, mammary implants, semiocclusive dressings, and drug delivery systems. The adoption and use of these materials by the medical community is likely to increase as new formulations are developed.
