Abstract
An indwelling urinary catheter having a palpitatable multi-axial dome-type discharge valve with protective shoulders. The protective shoulders are preferably raised above other unprotected portions of an outer surface of the valve. In preferred embodiments, the valve wall is made substantially of a first material and each of the protective shoulders include an elongated thickness of a second material which is more rigid than the first material. The valve has a peripheral trough to maximize drainage. Valve openings traverse an arcuate pathway, and adjacent valve elements are separated by an intermediate rib to ensure a reliable closure.
