ABSTRACT:
Urethral damming device for preventing uncontrolled discharge of urinary fluid in incontinent patients includes an elongate body formed of a flexible, resilient biocompatible material adapted to being inserted within a patient's urethra. The elongate body has a closed anterior end, an open posterior end, and an annular wall joining the anterior and posterior ends. The annular wall defines an interior recessed cavity which extends axially from the open posterior end of the elongate body toward the anterior end thereof. In use, the cavity receives urinary fluid passing through the patient's urethra which causes a pressure to be exerted upon the interior surface of the annular wall. This outward pressure responsively causes the annular wall to be flexed outwardly into sealing relationship with the patient's urethra. As a result, uncontrolled discharge of the urinary fluid is prevented.
