First Claim
Patent Images
1. A method of forming an implant, comprising:
- providing a non-porous, resorbable polymer base material; and
applying the resorbable polymer base material in a form of a resorbable membrane to an implant to thereby envelop substantially all of the implant, wherein the resorbable membrane is substantially non-porous and comprises a layer of polymer base material consisting essentially of one or more of;
a lactide polymer; and
/ora copolymer of two or more cyclic esters.

Abstract
An anti-adhesion membrane is placed onto an implant introduced into a surgical site of a patient to prevent post-surgical adhesions between the implant and surrounding tissue. The implant may comprise either biological material, such as a transplanted organ, or non-biological material such as a medical device. The membrane may be applied in a variety of ways. In one example, a membrane according to the present invention is shrink-wrapped around a pace-maker. In another example, a breast implant is spray-coated or dipped with the membrane material.
