Abstract

An implantable pump with a plurality of protrusions and grooves is described.

Claims

1. An implantable penile prosthesis comprising:

a reservoir, wherein said reservoir stores fluid;

a pump assembly, wherein said pump assembly is in fluid communication with the reservoir;

a cylinder in fluid communication with the pump assembly;

wherein said pump assembly includes a compressible bulb and a valve, wherein said valve includes a movable element that is positionable between a first position in a first flow path and a second position in a second flow path, the valve being changeable from a first configuration with the movable element in the first position with the second flow path open by compression of said compressible bulb so that a fluid pressure is generated within said pump assembly to act on said movable element to change the movable element from the first position to the second position and thus the valve from the first configuration to a second configuration with the first flow path open and the second flow path closed so as to permit valve operation to inflate said cylinder.

2. The implantable penile prosthesis of claim 1 further comprising a flexible housing within which the first and second flow paths are provided along with the first and second positions of the movable element, the housing also comprising an auto-deflate protrusion so that by compression of the housing at the auto-deflate protrusion, the movable element of the valve can be caused to move from the second position to the first position to open the second flow path and close the first flow path so as to permit valve operation to deflate said cylinder.

3. The implantable prosthesis of claim 1, wherein said movable element is moved between the first and second positions by way of a deformable portion of said pump assembly.
