Abstract

Precut, user-shapeable, resorbable polymer micro-membranes are disclosed. The micro-membranes are constructed of resorbable polymers, which are engineered to attenuate adhesions and to be absorbed into the body relatively slowly over time. 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.
