Abstract
Abstract A breast implant has at least an outer shell which is composed of a resorbable material. The implant, which can be formed entirely of bioresorbable material, is sized and shaped to replace excised tissue. The implant supports surrounding tissue upon implantation, while allowing for in-growth of fibrous tissue to replace the implant. According to various alternative embodiments, the implant is elastically compressible, or can be formed from self-expanding foam or sponges, and can be implanted through a cannula or by injection, as well as by open procedures. The implant also is capable of carrying therapeutic and diagnostic substances.
