Title:
BALLOON CATHETER HAVING PALPITATABLE DISCHARGE VALVE AND RETENTION COLLAR
Document Type and Number:
WIPO Patent Application WO1996026748
Kind Code:
A3
Abstract:
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.
