Patent ID: 8012502

Claim:
A system, comprising: a resorbable scar-tissue reduction micro-membrane for attenuating a formation of post-surgical scar tissue between a healing post-surgical site and adjacent surrounding tissue following an in vivo surgical procedure on the post-surgical site, the resorbable scar-tissue reduction micro-membrane having a pre-implant configuration that is defined as a configuration of the implant immediately before the implant is formed between the post-surgical site and the adjacent surrounding tissue, the resorbable scar-tissue reduction micro-membrane having a first substantially-smooth, drug-free, planar, non-porous side and a second substantially-smooth, drug-free, planar, non-porous side, the resorbable scar-tissue reduction micro-membrane resorbing from more than 6 months to 24 months, having a viscosity property from more than about 1 g/dL to 3.5 g/dL, and a single layer of resorbable polymer base material between the first substantially-smooth side and the second substantially-smooth side, the layer of resorbable polymer base material having a substantially uniform drug-free composition and comprising a polymer selected from the group consisting essentially of a lactide polymer, ethylene oxide and a copolymer of cyclic esters, a thickness of the layer of resorbable polymer base material, measured between the first substantially-smooth side and the second substantially-smooth side, being about 0.001 mm to 0.300 mm; and another resorbable membrane comprising opposing sides defining therebetween a single layer, which has a substantially uniform drug-free composition the same as that of the resorbable polymer base material, which comprises a thickness greater than the thickness of the layer of resorbable polymer base material and less than 2000 microns, and which comprises pores whereby the other resorbable membrane is permeable.
