Percutaneous implantable nuclear prosthesis

A valve assembly for inflating an implantable prosthetic device comprising an inner inflatable enclosure connected to an outer inflatable enclosure;

• the valve assembly comprising:
• an elastomeric membrane forming a passageway from an interior of the inner inflatable enclosure to an exterior of the outer inflatable enclosure, the elastomeric membrane having an opening into an interior of the outer inflatable enclosure;
• a valve core disposed in the passageway so that the elastomeric membrane surrounds the valve core, the valve core comprising a conduit extending from a first end to a second end;
• a resealable, puncturable membrane at the second end of the conduit of the valve core for providing resealable access to the inner inflatable enclosure;
• and
• an opening in the conduit extending from an interior of the conduit to an exterior of the conduit;
• the opening in the conduit of the valve core being offset from the opening in the elastomeric membrane to form a one way valve allowing material introduced into the interior of the conduit to pass into the interior of the outer inflatable enclosure.

An implantable prosthetic device comprising:

• an inner inflatable enclosure having a first opening and filled with a compressible gas;
• an outer inflatable enclosure having a first opening and filled with a cured silicone material, the outer inflatable enclosure substantially encapsulating the inner inflatable enclosure;
• a valve assembly sealingly coupled to the first opening of the outer inflatable enclosure and the first opening of the inner inflatable enclosure, the valve assembly comprising:
• a valve section disposed between a proximal end of the outer inflatable enclosure and a proximal end of the inner inflatable enclosure, wherein the valve section comprises a conduit having a sidewall with at least one opening extending through the sidewall;
• and, optionally,
• a reinforcement band around the periphery of the outer inflatable enclosure.
