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.

Urinary catheter having palpitatable discharge valve with protective

An indwelling urinary catheter having a palpitatable multiaxial dome-type valve and an inflatable anchoring balloon. The valve has a peripheral trough to maximize drainage. The catheter body and balloon are integrally molded from silicone to produce a uniform and symmetrical balloon shape. The balloon shape may be selectively altered by varying bonding patterns or wall thicknesses. Valve openings traverse an arcuate pathway, and adjacent valve elements are separated by an intermediate rib to ensure a reliable closure. Valve elements are readily displaced by a drainage tube connector that engages the valve body. A collar on the catheter body moves axially along helical threads to adjust tension on the balloon.
