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 such as a collagen foam, 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 can carry therapeutic and diagnostic substances.
Claims6
An implant for implantation in a human body comprising an outer shell of a resorbable material comprising collagen, the implant being formed to fit the shape and size of a cavity in the human body, the implant supporting tissue surrounding the cavity upon implantation and allowing for in-growth of fibrous tissue into and replacing the outer shell, and a resorbable core provided inside and surrounded by the outer shell and containing autologous material.
A breast implant comprising a matrix of protein material, the matrix comprising a foam having a porous structure for supporting surrounding tissue of a breast and configured to provide a framework for the in-growth of fibrous tissue into the matrix.
A breast implant comprising a matrix of protein material and having a porous structure for supporting surrounding tissue of a breast and configured to provide a framework for the in-growth of fibrous tissue into the matrix, wherein the matrix is self-expanding.
