<p>A mechanical penile prosthesis (1) includes a sleeve (4) that encapsulates a linear assembly (50) of cups (7), an actuating means (8) and a cable (11). The linear assembly (50) of cups (7) allows the prosthesis (1) to be bent from an erect position to a flaccid position. The actuating mechanism (8) includes a biasing member (19), a poppet (21) with first and second shoulders (22, 23), one or more sliding rings (25), and a flexible tine (24). Bending the prosthesis (1) from its erect position to its flaccid position causes the poppet (21) to move toward the distal end (3) of the prosthesis (1), allowing the tines (24) to lock behind the second shoulder (23). To return the prosthesis (1) to its erect state the prosthesis (1) is bent further until the sliding ring (25) separates the tines (24), allowing the biasing member (19) to force the second shoulder (23) past the tines (24); the tines (24) snapping back into a position on the proximal side (2) of the first shoulder (22). A second poppet (83)positioned at the distal end (3) of the prosthesis (1) or a second sliding ring (29) that envelopes the first sliding ring (60) may be included to allow the prosthesis (1) to be bent into a super flaccid position, allowing easier surgical implantation of the prosthesis (1).</p> |
