Breast prosthesis with biologically absorbable outer container

Abstract

Abstract A newly developed breast prosthesis overcomes the tightness and contracture of the fibrous capsule which forms around the existing prosthesis. The unique construction of the new prosthesis causes the capsule to form at a predetermined, controlled distance from the surface thereof. This prosthesis is constructed with a first phase or outer temporary component and a second phase or inner permanent component. The inner component is a container or sac of a flexible, non-absorbable material filled with a fluid or gel filler material. The temporary outer component is an outer container or cover of a material which is absorbable under the conditions of use, and an inert filler material, preferably an absorbable, biologically acceptable liquid, e.g. saline solution, filling the space between the inner and outer components. The inner component is preferably of silicone rubber film and is filled with a silicone gel. The outer portion is in the form of a sheet, film or coating of a material which can be absorbed in the body after surgical implantation. Suitable materials are ones which will be absorbed by phagocytosis or hydrolysis or other processes or which can be rendered absorbable by physical or chemical or enzymatic treatment or the like, prior to, during, or after surgical implantation. These materials include natural, synthetic or semisynthetic materials proven useful for surgical sutures and materials such as reconstituted collagen, polylactic acid, polyglycolic acid, polyglactin 910, reconstituted vegetable protein, etc.
