Bioabsorbable breast implant
DCFirst Claim
1. An implant for implantation in a human body comprising an outer shell of resorbable material and a resorbable inner fluid core, the implant being formed to fit the shape and size of a cavity in the human body, the implant being configured to be installed for supporting tissue surrounding the cavity and allowing in-growth of fibrous tissue into and replacing the outer shell.

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.

9. A method for replacing excised human breast tissue with an implant comprising the steps of:
-
forming a cavity having surrounding tissue within a breast;
forming the implant entirely of resorbable material and sizing the implant to occupy the cavity; and
implanting the implant in the cavity, the implant supporting the surrounding tissue and allowing for in-growth of fibrous tissue into and replacing the resorbable material wherein the resorbable material is elastically compressible, and the step of implanting includes the step of compressing the resorbable material. - View Dependent Claims (10, 11, 16)

22. A method for replacing excised human breast tissue with an implant comprising the steps of:
-
forming a cavity having surrounding tissue within a breast;
forming the implant entirely of resorbable material and sizing the implant to occupy the cavity; and
implanting the implant in the cavity, the implant supporting the surrounding tissue and allowing for in-growth of fibrous tissue into and replacing the resorbable material, wherein the resorbable material is formed from a self-expanding foam and the step of implanting is performed by injection of the self-expanding foam. - View Dependent Claims (23, 24)
