Abstract
A mechanical device for treatment of impotence based on the concept of entrapment of blood in the penis following vacuum-assisted tumescence is described and more than 15,000 units have been marketed. A total of 1,517 users who acquired the device between 1974 and 1987 completed a questionnaire concerning the system. Of these patients 92 per cent either achieved an erection or an erection-like state that was satisfactory for intercourse and 77 per cent had intercourse at least every 2 weeks. No serious ill effect from use of the device has been reported and it is particularly effective in the management of partial impotence. In selected patients the device is an alternative to either surgical placement of a penile prosthesis, intracavernous injection of vasoactive drugs or sexual abstinence.
