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.

[ What is claimed is:] [1.] An implant for the body, comprising, in combination:a) a resilient envelope;b) fill material in the envelope to provide a volume to the envelope; andc) a valve, with the valve being adapted to receive a tube for introducing fill material into the envelope, with the valve comprising:i) a resilient primary closure for sealing the fill material in the envelope, with the primary closure being opened and closed when the tube is inserted into and withdrawn from the valve; andii) a resilient secondary closure, with the secondary closure being opened and closed when the tube is inserted into and withdrawn from the valve, with the resilient secondary closure being disposed outwardly relative to the primary closure such that when the tube is inserted into the valve the tube first opens the secondary closure and then opens the primary closure and such that when the tube is withdrawn from the valve the primary closure closes first automatically and the secondary closure closes second automatically.
