<p>This invention is an indwelling urinary catheter (10) having a palpitatable multi-axial dome-type valve (38), and an inflatable anchoring balloon (18). The valve (36) has a peripheral trough (75) to maximize drainage. The catheter body (12) and balloon (18) 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 (76) traverse an arcuate pathway, and adjacent valve elements are separated by an intermediate rib (78) to ensure a reliable closure. Valve elements are readily displaced by a drainage tube connector that engages the valve body. A collar (20) on the catheter body (12) moves axially along helical threads to adjust tension on the balloon.</p> |
