Abstract
Resorbable three-dimensional implants that can be temporarily deformed, implanted by minimally invasive means, and resume their original shape in vivo, have been developed. These implants are particularly suitable for use in minimally invasive procedures for tissue reinforcement, repair of hernias, and applications where it is desirable for the implant to contour in vivo to an anatomical shape, such as the inguinofemoral region. In the preferred embodiment, the implants are made from meshes of poly-4-hydroxybutyrate monofilament that have reinforced outlying borders that allow the meshes to form three-dimensional shapes that can be temporarily deformed. These implants can resume three-dimensional shapes after being temporarily deformed that contour to the host's tissue or an anatomical shape, for example, in the repair of a hernia, and particularly a hernia in the inguinofemoral region. The implants can contour to the host's tissue for example, of the inguinofemoral region, without the implants wrinkling, bunching or folding.
