Abstract: A male impotency aid device for enabling a man to acquire and maintain an erect penis which has a rigid tubular portion having an inner surface that is sized to fit snugly on the penis without strangulation and that has an inner surface with a notch extending the length of the tubular member that is aligned with the penile urinary tract and which has an annular rim that extends outward from the outer surface of the tubular portion. The device is applied over the penis such that an end surface on the tubular portion comes into contact with the crus of the user's penis to stimulate the penis to obtain an erection without strangulation. The inner surface then acts to limit the bloodflow from the penis to help maintain the erection, also without strangulation.
