Abstract
An improved fluid-filled breast prosthesis for implantation which permits subsequent alterations in the fluid volume of the implant without the necessity for major surgery. The prosthesis comprises a flexible plastic bag having an elongated filler tube including a loop near its outer end. After the prosthesis has been interposed into the surgically prepared implant site, the filler tube is drawn out through a small stab wound connected to the site which terminates adjacent the arm pit. After the plastic bag is filled with fluid, the filler tube is plugged and clamped, and the loop is sutured to the tissue to hold the implant in place. The radiopaque nature of the plug and clamp, and a connected filament, enable the end of the tube to be readily located and grasped subsequent to the operation, using a simple office procedure to adjust the volume of fluid in the bag.
