1. A system, comprising:
- a resorbable scar reduction 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 reduction 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 reduction membrane having a first substantially-smooth side and a second substantially-smooth side;
the resorbable scar reduction membrane comprising a 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 composition, a thickness of the layer of resorbable polymer base material, measured between the first substantially-smooth side and the second substantially-smooth side, being between 10 microns and 300 microns; and
another membrane, which comprises a thickness less than 2000 microns and which is permeable.

Abstract
Resorbable lactide polymer thin membranes are disclosed. The thin membranes are constructed of polylactide resorbable polymers, which are engineered to be absorbed into the body relatively slowly over time in order to reduce potential negative side effects. The membranes are formed to have very thin thicknesses, for example, thicknesses between about 0.010 mm and about 0.30 mm. The membranes can be extruded from polylactide polymers having a relatively high viscosity property, can be preshaped with relatively thick portions, and can be stored in sterile packages.
