Abstract
An implant that includes an envelope, a saline based fill material in the envelope, and a single valve. The envelope is formed by a mandrel dipping process and includes an opening formed by a support rod for the mandrel. To remove the envelope from the mandrel, the opening is stretched over the mandrel. This opening, a natural port, is sealed by a single valve structure. The valve structure includes the valve through which the saline based fill material is introduced. The valve is two piece, and the two pieces mechanically interlock to bias and draw a diaphragm tightly against a valve seat, which provides a primary resilient closure for the valve. The valve further includes a secondary resilient closure where two confronting faces form a slit through which a filling tube is inserted and where end portions of the two confronting faces are bonded to each other to minimize the chances of the slit tearing at its ends.
