Abstract: A vacuum erection control system for erectile dysfunction treatment. The vacuum erection control system includes a vacuum erection device, including a vacuum chamber and a thin elastic seal element. The vacuum chamber has a distal end for operable connection to a vacuum generating means, an open proximal end, an inside surface and an outside surface. The thin elastic seal element is formed of a stretchable material having a first seal end and a second seal end. The first seal end is stretched for removable sealing placement on the proximal end of the vacuum chamber. The second seal end has a central orifice forming a penile seal for the sealable introduction of a penis. The stretchable material is substantially non-permeable to air and expandable to at least twice its original area without losing this non-permeable characteristic.
