Abstract
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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
63 words
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.
Claim 2
Dependent Claim
63 words
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.
Claim 3
Dependent Claim
25 words
The device of claim 1 wherein the valving portion includes at least one biased check ball that is unseated when the valving portion is deformed.
Claim 4
Dependent Claim
23 words
The device of claim 2 wherein the valving portion includes two biased check balls that are unseated when the valving portion is deformed.
Claim 5
Dependent Claim
18 words
The device of claim 1 wherein the cushioning means includes a silicone gel enclosed by a silicone elastomer.
Claim 6
Dependent Claim
18 words
The device of claim 1 wherein the cushioning means includes a silicone gel enclosed by a polyurethane elastomer.
Claim 7
Dependent Claim
20 words
The device of claim 1 wherein the cushioning means includes a generally cylindrically configured cushioning material surrounding the valving portion.
Claim 8
Dependent Claim
14 words
The device of claim 6 wherein the cushioning means has an elliptical cross section.
Claim 9
Dependent Claim
16 words
The device of claim 1 wherein the means for pumping fluid is disposed within the cylinder.
Claim 10
Dependent Claim
96 words
The device of claim 1 wherein the valving portion includes 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.
