1. An inflatable penile prosthesis comprising:
- a body implantable cylinder that is reversibly movable between an inflated state and a deflated state, the body implantable cylinder having opposed first and second ends disposed on a central longitudinal axis, the body implantable cylinder comprising;
in cross section, when deflated, a plurality of protrusions and a plurality of intermediate portions disposed about the central longitudinal axis, the protrusions disposed a first distance away from the central longitudinal axis and the intermediate portions disposed a second distance away from the central longitudinal axis, the second distance less than the first distance; and
in cross section, when inflated, the plurality of intermediate portions expand to a distance of approximately the first distance away from the central longitudinal axis;
wherein the plurality of protrusions and the plurality of intermediate portions combine to form a plurality of leafs disposed around the central longitudinal axis configured to resist outward bending of a wall of the body implantable cylinder.

Abstract
An implantable fluid device comprises a flexible fluid chamber capable of being in an inflated state and a deflated state. The chamber has a first end, a second end, and a central longitudinal axis from the first end to the second end. The chamber also has, in cross section when deflated, a plurality of alternating protrusions and intermediate portions about the central longitudinal axis. When deflated, the protrusions have a selected height and the intermediate portions have a selected depth. When inflated, the protrusions have the selected height and the intermediate portions have a selected height.

4. An implantable fluid device, comprising:
-
a body implantable fluid reservoir reversibly movable between an inflated state and a deflated state, said fluid reservoir comprising a wall that defines a closed first end and a second end having an opening configured to provide fluid communication between an implantable penile prosthesis and said fluid reservoir, and a central longitudinal axis extending from said first end to said second end, said fluid reservoir further comprising; in cross section, when deflated, a plurality of alternating protrusions and intermediate portions that terminate at said closed first end and are disposed about said central longitudinal axis, with said protrusions disposed a first distance away from said central longitudinal axis and said intermediate portions disposed a second distance away from said central longitudinal axis, said second distance less than said first distance; and in cross section, when inflated, said plurality of intermediate portions expand to a distance of approximately said first distance away from said central longitudinal axis. - View Dependent Claims (5, 6)
