A device that is applied externally to the penis for the management of erectile dysfunction (ED) (commonly known as impotence) to achieve selective penile tumescence and rigidity adequate for vaginal intercourse. It is typically a two-component device consisting of: 1) a manually-operated, vacuum pump/sleeve which is applied over the flaccid penis and used to create a vacuum to achieve tumescence through an up and down movement along a vacuum tube; and 2) a constriction ring used in conjunction with the pump and placed upon the penis to maintain the erection. The ring remains on the penis for a recommended period of time. This is a reusable device.
