Urinary flow control device and method
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.
1. An endourethral device comprising an elongate body having proximal and distal end portions and a lumen therethrough for urine passage, said proximal end portion including an anchoring element for engagement with a portion of a bladder neck and a fluid filled plug, said fluid filled plug having first and second portions wherein said first portion sectionally traverses a segment of said lumen so as to form a seal with a lumen defining wall of said elongate body, said first portion of said fluid filled plug being responsive to increasing bladder pressure such that said seal is deformed so as to thereby permit urine passage between said wall and said first portion of said fluid filled plug.
2. The device of claim 1 wherein portions of said first and second portions of said fluid filled plug comprise compartments.
3. The device of claim 2 wherein said compartments are operatively linked for fluid transfer therebetween.
4. The device of claim 3 wherein fluid is transferred between compartments as a function of increasing bladder pressure.
5. The device of claim 3 wherein fluid transfer between said compartments is regulated by a flow regulating mechanism.
6. The device of claim 5 wherein said flow regulating mechanism is actuatable.
7. The device of claim 6 wherein said fluid transfer between said compartments is facilitated by actuation of said flow regulating mechanism.
8. The device of claim 5 wherein said flow regulating mechanism is remotely actuatable.
9. The device of claim 1 wherein said first and second portions of said fluid filled plug are operatively linked by a fluid flow regulator.
10. The device of claim 9 wherein actuation of said fluid flow regulator enhances the responsiveness of said first portion of said fluid filled plug to increasing bladder pressure.
11. The device of claim 1 wherein said anchor element is reversibly expandible.
12. The device of claim 11 in combination with an insertion tool, said anchor adapted to receive fluid via said insertion tool.
13. The device of claim 1 wherein said anchor element circumscribes at least a portion of said proximal end portion.
14. The device of claim 1 wherein said anchor element is adapted for selective receipt of fluid in furtherance of engagement with the bladder neck.
15. The device of claim 14 wherein said distal anchor element is adapted for selective receipt of fluid in furtherance of engagement with a portion of the bulbous urethra.
16. The device of claim 14 in combination with an insertion tool, said anchors adapted to receive fluid via said insertion tool.
17. The device of claim 1 wherein said distal end portion includes a distal anchor element for engagement with a portion of a bulbous urethra.
18. The device of claim 17 wherein said distal anchor element is reversibly expandible.
19. The device of claim 17 wherein said distal anchor element circumscribes at least a portion of said distal end portion.
