Urinary flow control device and method
First Claim
1. A urinary flow control device comprising:
- a. an elongate member having proximal and distal ends, and a lumen capable of discharging urine therethrough; and
, b. a sealed flow control assembly comprising first and second fluid containing compartments adapted to be in fluid communication, said sealed flow control assembly operatively joined to said elongate member such that urine entering said elongate member impinges upon said first fluid containing compartment, said flow control assembly being responsive to increased bladder pressure such that fluid is displaced from said first fluid containing compartment to said second fluid containing compartment to thereby permit select passage of the urine entering said elongate member to said lumen thereof for discharge therethrough.

Abstract
A urinary flow control device having a bladder responsive flow control assembly operatively engaged with an elongate member having proximal and distal ends, and a lumen capable of discharging urine therethrough is provided. The flow control assembly includes first and second fluid containing compartments adapted to be in fluid communication. The flow control assembly is adapted to receive and contain urine from a bladder so as to impinge upon the first fluid containing compartment. The flow control assembly is responsive to increased bladder pressure such that fluid is displaced from the first fluid containing compartment to the second fluid containing compartment to thereby permit select passage of received urine to the lumen of the elongate member for discharge therethrough. A method of controlling urinary flow is likewise provided.

7. A urinary flow control device comprising:
-
a. an elongate member having proximal and distal ends, and a lumen capable of discharging urine therethrough; and
,b. a flow control assembly comprising first and second fluid containing compartments joined by primary and secondary fluid passages, said flow control assembly operatively joined to said elongate member and adapted to receive and contain urine from a bladder so as to impinge upon said first fluid containing compartment, said flow control assembly being responsive to increased bladder pressure such that fluid is displaced from said first fluid containing compartment to said second fluid containing compartment via said primary fluid passage to thereby permit select passage of received urine to said lumen for discharge therethrough, said a secondary fluid passage permitting fluid communication between said first fluid containing compartment with said second fluid containing compartment so as to provide automatic pressure relief to the bladder by displacement of fluid from said first fluid containing compartment to said second fluid containing compartment. - View Dependent Claims (8, 9, 10)

18. An indwelling urinary flow controller comprising:
-
a. a controller body for engaging a portion of a bladder, said controller body adapted to receive urine from the bladder;
b. a fluid reservoir; and
,c. a fluid containing capsule adapted to be in fluid communication with said fluid reservoir so as to define a sealed fluid assembly, said fluid containing capsule having a deformable membrane responsive to urine received by said controller body such that fluid passes between said fluid containing capsule and said reservoir with changes in bladder pressure, said sealed fluid assembly positioned within said controller body such that said deformable membrane sealingly engages an interior portion thereof to block discharge of urine received by said controller body from said flow controller, said deformable membrane being responsive to increased bladder pressure such that fluid passes from said fluid capsule to said fluid reservoir so as to disengage at least a portion of said deformable membrane from said interior portion of said controller body to permit drainage of urine from said controller body.

- 19. In a urethral catheter adapted to receive urine from a bladder, a flow control device for regulating egress of urine from the bladder, said device subject to bladder pressure and comprising a sealed fluid element having a first fluid region, a second fluid region, and a hydraulic linkage therebetween, said sealed fluid element being hydraulically responsive to a range of preselected bladder pressure such that fluid within said sealed fluid element shuttles from one of said fluid regions to another of said fluid regions, thereby permitting selective urine discharge via the urethral catheter.
