A combination seal and constricting device and method of use for the external treatment of impotence is provided. The subject device is made of a pliable elastomeric material and is characterized by a centrally disposed cylindrical collar connected at one end thereof to a radially extending skirt having a forwardly facing, annular, elastomeric seating and sealing surface and a rearwardly facing surface substantially flush with one end of said collar. When used in combination with a conventional vacuum erection device, the combination seal and constricting device is positioned at the open end of the evacuation cylinder of the conventional vacuum erection device with the radially extending skirt flush between the open end of the cylinder and the user's groin. In this position, the subject device aids in establishing and maintaining a substantially airtight seal around the open end of the cylinder and the base of the penis during evacuation pumping.
A combination seal and constricting device adapated for use in the external treatment of erectile dysfunction, comprising a substantially cylindrical elastomeric collar having a diameter expandable to accommodate a penis and a radially extending skirt having a forwardly facing, annular, elastomeric seating and sealing surface, a rearwardly facing surface substantially flush with one end of said collar, and a skirt edge, said skirt having a circumference and a radius extending from said collar to said skirt edge, the radius being substantially greater than the unexpanded collar diameter around the entire circumference.
