SURGICAL PROSTHESIS HAVING BIODEGRADABLE AND NONBIODEGRADABLE REGIONS
First Claim
1. A surgical implant for implantation in a host, comprising:
- a substantially planar barrier membrane of resorbable polymer base material including (i) an adhesion-resistant region with a biodegradable component, and (ii) a tissue-ingrowth region that differs from the adhesion-resistant region in one or more of surface appearance and surface function, anda thermoplastic component contacting one or more of the tissue-ingrowth region and the adhesion-resistant region.

Abstract
A prosthesis for repairing a hernia includes an adhesion-resistant biodegradable region and an opposing tissue-ingrowth biodegradable region. When the prosthesis is implanted into the patient, the adhesion-resistant biodegradable region covers a fascial defect of the hernia, and the tissue-ingrowth biodegradable region is located above the adhesion-resistant biodegradable region while being exposed substantially only to the host'"'"'s subcutaneous tissue layer. This orientation allows the tissue-ingrowth biodegradable region to become firmly incorporated with the host'"'"'s body tissue. The adhesion-resistant biodegradable region faces the internal organs and decreases the incidence of adhesions and/or bowel obstruction.
