MICRO-MEMBRANE IMPLANT WITH CUSPED OPENING
First Claim
1. A resorbable scar-tissue reduction micro-membrane system 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 system having a pre-implant configuration, which is defined as a configuration of the system immediately before the system is formed between the post-surgical site and the adjacent surrounding tissue, the system comprising a substantially planar membrane of resorbable polymer base material having a first substantially-smooth side and a second substantially-smooth side, the substantially planar membrane of resorbable polymer base material comprising a single layer of resorbable polymer base material between the first substantially-smooth side and the second substantially-smooth side, the single layer of resorbable polymer base material including a cusped orifice.

Abstract
Precut, user-shapeable, resorbable polymer micro-membranes having cusped orifices are disclosed. The micro-membranes are constructed of resorbable polymers, which are engineered to attenuate adhesions. The membranes can formed to have very thin thicknesses, for example, thicknesses between about 0.010 mm and about 0.300 mm, while maintaining adequate strength. The membranes can be extruded from polylactide polymers having a relatively high viscosity property, can be stored in sterile packages, and can be preshaped with relatively high reproducibility during implantation procedures.
