Abstract:
1. A valve assembly positionable within a housing for an implantable penile prosthesis for moving fluid between a cylinder outlet in fluid communication with at least one cylinder and a reservoir inlet in fluid communication with a reservoir along a valve flow path, the valve assembly comprising: a cylinder poppet comprising a cylinder poppet bore, a cylinder poppet sealing surface, a cylinder annulus, and a cylinder poppet spring that biases the cylinder poppet toward the cylinder annulus; a suction poppet comprising an elongated suction poppet shaft that is slideably engaged within the cylinder poppet bore to retain axial alignment of the suction poppet and cylinder poppet along a central axis, a suction poppet sealing surface, a suction annulus, and a suction poppet spring that biases the suction poppet toward the suction annulus; wherein the valve flow path is defined between the reservoir inlet and the cylinder outlet, the valve flow path being fluidly connected to a pump bulb opening, the valve flow path extending linearly along the central axis with the suction poppet and the cylinder poppet positioned within the valve flow path and being movable along the central axis, the cylinder poppet further including an extended cylinder shaft that is slidably received within a cylinder journal positioned within the housing and integral to the valve flow path, wherein the engagement between the cylinder journal and extended cylinder shaft retain axial alignment of the cylinder poppet along the central axis as the cylinder poppet transitions between an engaged position and a disengaged position.
