Penile prosthesis
First Claim
1. A penile implant device in fluid communication with an implantable reservoir, the device comprising:
- a pressurizable cylinder adaptable for implantation, the cylinder including a pressurizable chamber and a means for pumping fluid from the reservoir to the pressurizable chamber, a deformable valving portion disposed within the cylinder, and cushioning means surrounding the valving portion whereby accidental deformation of the valving portion is minimized.

Abstract
A penile implant includes an elongated member for implantation in the penis that is in fluid communication with a reservoir. The member includes an enclosure having a pressurizable chamber section such that the member is transformable between a flaccid and an erect state and a pump for transferring fluid from the reservoir to the pressurizable chamber. The pump has a valve portion made of a deformable material such that when the valve portion is deformed, fluid flows from the pressurizable chamber to the reservoir making the member flaccid. The valve portion is surrounded by a cushioning material to protect the valve portion from being accidentally deformed, permitting fluid to flow from the pressurizable chamber back to the reservoir.

18. A penile implant device in fluid communication with an implantable reservoir, the device comprising:
a pressurizable cylinder adapted for implantation, the cylinder including a pressurizable chamber and a means for pumping fluid from the reservoir to the pressurizable chamber, a deformable valving portion disposed within the cylinder, the valving portion including two biased check balls, one check ball restricting flow between the chamber to the means for pumping fluid and the other check ball restricting flow between the reservoir to the means for pumping fluid, and a valve seat against which each check ball is biased, the valve seats being disposed on opposite sides of a plane perpendicular to a longitudinal axis of the cylinder such that the check balls are unseated primarily due to deformation of the valve portion along the longitudinal axis of the cylinder. - View Dependent Claims (19)
