  • Device for maintaining an erection
    Patent number: 5921914
    Abstract: A device for maintaining an erection of a penis has a flexible cuff around the penis. A line extends around the cuff. The line tightens or loosens the cuff around the penis. A bead, through which the line extends, locks the line so that cuff maintains the line and cuff in the tightened position. The cuff has multiple circumferentially ridges, and the line extend between two adjacent ridges. A bead also locks the line in the tightened position. The cuff provides a seal between the hose of a vacuum device and the penis so that the vacuum can cause an erection. While the vacuum is still applied, the line is tightened to constrict the penis so that the erection is maintained. Once the line is tightened, the vacuum hose can be removed. The user then can engage in sexual intercourse.
