-
Thin pieces of material shaped and designed for implantation as vascular and/or cardiac patches to repair vasculature and/or heart structures. These patches usually consist of thin, sterile materials that are biocompatible and can endure the physical stress suffered by the vascular and cardiac structures; typical patches are made of polymers (e.g., polyester, Teflon) and gel sealants. Cardiovascular patch implants are intended for surgical repair of the vasculature and structures around and/or in the heart, including patching of the carotid arteries after endarterectomy and repair of congenital defects in the vasculature and/or hearts of children.
