Apparatus and method for preventing adhesions between an implant and surrounding tissues
First Claim
1. A method for attenuating adhesions between an implant and surrounding tissue following a surgical procedure in a patient, the method comprising:
- providing a non-porous, resorbable polymer base material; and
applying the resorbable polymer base material in a form of a resorbable thin membrane around the implant to thereby cover substantially all exposed surfaces of the implant, wherein the resorbable thin membrane is substantially non-porous and comprises a layer of polymer base material selected from the group consisting essentially of;
a lactide polymer; and
a 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.

30. An apparatus comprising:
-
an implant configured to be inserted into a surgical site of a patient surrounded by tissue, wherein when the implant is inserted into the surgical site, tissue surrounds and contacts substantially all of an exterior surface of the apparatus; and
a resorbable membrane surrounding the implant for attenuating adhesions between the implant and the surrounding tissue, the resorbable membrane being disposed over substantially all of the exterior surface of the implant. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
