Abstract
The present invention features soft tissue implants and methods for making same. The implants can includes a biocompatible film that is rendered porous due to the inclusion of uniformly or non-uniformly patterned cells, and the film has a thickness of less than about 0.015 inches in the event the starting material is non-porous and less than about 0.035 inches in the event the starting material is a microporous film. Multi-film implants can also be made.
