Patent ID: 8048444

Claim:
A method of forming an implant, comprising: providing a non-porous, resorbable polymer base material comprising a property of resorbing from more than 6 months to 24 months and a viscosity property from 1 g/dL to 3.5 g/dL; 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 having a thickness of about 0.01 mm to 0.300 mm and a polymer material consisting essentially of one or more of a lactide polymer and a copolymer of two or more cyclic esters; the resorbable membrane comprises a substantially planar membrane of resorbable polymer base material having a first substantially smooth side and a second substantially smooth side; the membrane of polymer base material comprises a single layer of resorbable polymer base material; and the single layer of resorbable polymer base material is adapted to maintain a smooth-surfaced barrier between the implant and substantially all surrounding tissue.
