Abstract: An elastic band with a tapered bore extending therethrough is positioned on the base of the penis for maintaining a penile erection. Flanges extend radially from the base of the band to stretch it and spread it sufficiently for application. When the stretching force is released the residual elastic force in the band constricts the base of the penis to restrict outflow of blood from the base of the penis. The elongated structure also provides physical support at the base of the penis as an aid in supporting a penis afflicted by Peyronie's disease or the like at the penis base.

Abstract: Gripping cutters have either shearing blades or blade-and-anvil cutting members. Attached to one lateral side of each cutting member is a movable jaw arranged to grip the elements being cut when the cutter is closed and to release the elements when open. Each jaw has a pair of elongate parallel pins extending from its rear face. A pair of supports affixed to each lateral side have an aperture for slidably receiving a pin. A compression spring on the pin forces the jaws together and an adjustable stop on the pin limits the extent of the jaw movement so that the relative position of the blades at the moment of release of the cut elements may be adjusted. Resilient jaw faces may be provided for gripping small and large branches simultaneously.

Abstract: A device for affecting or enhancing erection of the penis comprises an external inflatable cuff which encircles the shaft of the penis at its base and extends distally. The cuff is provided with a plurality of volume expandable annular spaces arranged parallel to one another. The spaces are filled with fluid under pressure from a squeeze bulb to affect a tourniquet action. The spaces are inflated sequentially in a proximal to distal direction. As the spaces become sequentially pressurized, the inner diameter of the cuff is reduced, constricting the penis and trapping blood within the shaft and forcing it distally to thereby increase the rigidity of the penis.
