Biopsy cavity marking device and method

摘要

These are breast implant devices and methods of use. The breast implants are made of a matrix of collagen material having a porous structure for supporting surrounding tissue of a breast. The implants are also configured to provide a framework for the in-growth of fibrous tissue into the matrix. The matrix can be resilient and/or self-expanding. The methods of use include the steps of forming a cavity having surrounding breast tissue and forming a resorbable implant made up of collagen that is sized to occupy the cavity. The implant is then implanted into the cavity, thereby supporting the surrounding tissue and allowing for in-growth of fibrous tissue into and replacing the resorbable material. The resorbable material may also be elastically compressible, such that the step of implanting includes the step of compressing the resorbable material. The implants may also contain a medicinal, therapeutic, or diagnostic substance.
