Abstract
A dual poppet valve assembly for a pump assembly of an implantable penile prosthesis having a suction poppet engagable by a plurality of fingers allowing free travel of the poppet and to prevent vacuum lockup of the pump assembly. The suction poppet can also include an elongated shaft receivable within a corresponding bore of a cylinder poppet to prevent the suction poppet from becoming misaligned during the operation of the pump assembly.
Claims17
A valve assembly for an implantable penile prosthesis, comprising:
- a valve flow path defined between a reservoir inlet and a cylinder outlet, the valve flow path being fluidly connected to pump bulb opening, the valve flow path extending linearly along a valve chamber axis with a suction poppet and a cylinder poppet positioned within the valve flow path and being movable along the valve chamber axis, the cylinder poppet including an extended cylinder shaft that is slidably received within a cylinder journal integral to the valve flow patch, wherein the interaction of the cylinder journal and extended cylinder shaft retain axial alignment of the cylinder poppet along the valve chamber axis as the cylinder poppet transitions between an engaged position and a disengaged position.
A valve assembly for an implantable penile prosthesis, comprising:
- a valve flow path defined between a reservoir inlet and a cylinder outlet, the valve flow path being fluidly connected to pump bulb opening, the valve flow path extending linearly along a valve chamber axis with a suction poppet and a cylinder poppet positioned within the valve flow path and being movable along the valve chamber axis, wherein the valve flow path defines a suction annulus including a plurality of protruding fingers, the suction poppet positioned through the suction annulus such that the plurality of protruding fingers retain the suction poppet along the valve chamber axis.
A valve assembly for an implantable penile prosthesis, comprising:
- a valve flow path defined between a reservoir inlet and a cylinder outlet, the valve flow path being fluidly connected to pump bulb opening, the valve flow path extending linearly along a valve chamber axis with a suction poppet and a cylinder poppet positioned within the valve flow path and being movable along the valve chamber axis, wherein the suction poppet is actuatable with a release button, the release button contacting an elongated head on the suction popped to direct the suction poppet along the valve chamber axis.
