Reinforced tissue implants and methods of manufacture and use
First Claim
1. A biocompatible tissue implant, comprising:
- a bioabsorbable polymeric foam component having pores with an open cell pore structure; and
a reinforcing component formed of a biocompatible, mesh-containing material, the foam component being integrated with the reinforcing component such that the pores of the foam component penetrate the mesh of the reinforcing component and interlock with the reinforcing component.

Abstract
A biocompatible tissue implant, as well as methods for making and using such an implant, is provided. Preferably, the tissue implant is bioabsorbable. The tissue implant comprises one or more layers of a bioabsorbable polymeric foam having pores with an open cell structure. The tissue implant also includes a reinforcement component which contributes both to the mechanical and the handling properties of the implant. Preferably, the reinforcement component of the instant invention is bioabsorbable as well. The tissue implant of the present invention can be used in connection with the surgical repair of soft tissue injury, such as injury to the pelvic floor.
