Abstract:
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the fill material in the envelope, with the primary closure being opened and closed when the tube is inserted into and withdrawn from the valve; andii) a resilient secondary closure, with the secondary closure being opened and closed when the tube is inserted into and withdrawn from the valve, with the resilient secondary closure being disposed outwardly relative to the primary closure such that when the tube is inserted into the valve the tube first opens the secondary closure and then opens the primary closure and such that when the tube is withdrawn from the valve the primary closure closes first automatically and the secondary closure closes second automatically.
