Abstract: The construction of an integral cincture band of elastic material may include a pair of semi-ellipsoidal handles and an enlarged region to be aligned with the urethra of the user's male sex organ so as to relatively reduce the urethral constriction for improved seminal fluid discharge. Radially inwardly projecting regions of predetermined radius of curvature which is relatively large to the overall ring may be provided in predetermined circumferential locations on each lateral side of the dorsal centerline. By such arrangement, effective pressure is applied to the subcutaneous lateral veins and generally to the dorsal venous process of the penis without direct application of constrictive force to the center of the penis dorsal area, thereby minimizing user pressure discomfort or loss of sensation.

Abstract: An improved apparatus for augmenting male potency generally includes a cylindrical vacuum chamber adapted to cover a male sex organ. The vacuum chamber has an open proximal end and a closed distal end. The distal end is tapered to provide an integral ramp for expanding a resilient cincture band onto the outside diameter of the vacuum chamber. A vacuum connector fitting is formed at the base of such ramp for evacuation of the vacuum chamber. Guard flanges help protect the fitting. The proximal end includes a cincture band groove defined about the outside diameter of the vacuum chamber, with a plurality of vent holes formed in the groove and pneumatically interconnecting the exterior of the vacuum chamber with its interior. A cincture band which has been expanded onto the outside diameter of the vacuum chamber and advanced to its proximal end initially resides in the cincture band groove, where it covers and seals the plurality of vent holes.
