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.
