Abstract: A prosthesis for supporting tissue and a method for implanting the prosthesis are disclosed wherein the prosthesis may be easily repositioned subsequent to implantation. The prosthesis is formed with a flexible core which is elastic in the longitudinal direction, and one end of the prosthesis is provided with a tissue ingrowth surface to receive tissue growth. The remainder of the prosthesis is covered with a biocompatible covering which tends to seal against sutures or other anchoring units which pierce the covering. The flexible cover is formed to accept such anchoring units without tearing.

Abstract: The instant invention is directed to a mammary prosthesis injector. The injector comprises a hollow tube having an opening at one end thereof. A bag for holding the prosthesis and reducing friction between the tube and the prosthesis is located, in part, within the tube. A mechanism for pulling the bag from within the tube is slidably mounted on the exterior of the tube and engages the bag. The prosthesis, which is held within the bag which is within the tube, is ejected from the tube and through the opening when the pulling mechanism is slid along the exterior of the tube.
