Figure 1. The unpopularity of older cuff and clamp designs can be seen here with Adult Diapers being the main solution and clamps not even making the list. The users preference for treatment options have generally avoided the devices because of pain and circulation issues.
The prototyping period of Pacey Cuff™ development produced a great many devices that had variable success with control of the Urethral urine flow but all of the devices used the fenestrated hood design and the exceptionally effective hood covering the blood vessels of the dorsal area. The devices were applied to a degree necessary to control urine and then each was tested with the handheld Doppler device to locate an arterial signal on the right side and the left side. All of the prototypes passed this test confirming that the blood supply was unaffected. This testing does not however prove that every penis will have adequate circulation because the presence of extensive atherosclerotic vascular disease, previous trauma, or disease like Diabetes Mellitus can have unpredictable local effects.
