Abstract
An expanded elastic ring is supported in an annular groove within a ring outer cylinder for use in vacuum therapy of a dysfunctional penis. The cylinder has an open end for initial placement against a user's body with the penis contained within the cylinder. The cylinder further comprises a cap on a closed end into which a vacuum pump is integrated. The elastic ring expanded around an inner cylinder into an annular groove is remotely released within a vacuum drawn within the cylinder. In a first embodiment, the vacuum effects the release as the inner cylinder is withdrawn into an outer cylinder until the ring falls off of the inner cylinder end. In a second embodiment, push rods extending into the annular groove push the ring past a stationary inner cylinder, effected by rotation of the cap on the cylinder. An inclined face on the cap bottom surface engages the rod, pushing the rod into the annular groove.
