Internal urinary catheter
First Claim
1. An internal urinary catheter, comprising:
- a cannula having a urine passage, a urine inlet and a urine outlet; and
valve means positioned along said urine passage between said inlet and said outlet and comprising a valve passage having at least a portion which is moveably positioned between a substantially blocked position and a flow position, and means for moving said portion, said means for moving being biased toward a blocking position wherein said portion is in said substantially blocked position and flow through said valve means is substantially blocked, and said means for moving being moveable to a released position at least partially moving said portion toward said flow position wherein flow through said valve means is allowed, wherein said portion comprises a compressible tube, and wherein said means for moving comprises means for releasably compressing said tube in said substantially blocked position, said means for releasably compressing being positionable to said released position wherein compression of said tube is at least partially reduced.

25. An internal urinary catheter, comprising:
-
a cannula having a urine passage, a urine inlet and a urine outlet; and valve means positioned along said urine passage between said inlet and said outlet and comprising a valve passage having at least a portion which is moveably positioned between a substantially blocked position and a flow position, and means for moving said portion, said means for moving being biased toward a blocking position wherein said portion is in said substantially blocked position and flow through said valve means is substantially blocked, and said means for moving being moveable to a released position at least partially moving said portion toward said flow position wherein flow through said valve means is allowed, wherein said portion comprises a valve passage member having a valve passage defined therein, said valve passage member being movably mounted in said valve means between said blocked position wherein said valve passage is substantially isolated from said urine passage and flow through said valve means is substantially blocked, and said flow position wherein said valve passage is communicated with said urine passage and flow through said valve passage and said valve means is allowed. - View Dependent Claims (26, 27, 28, 29, 30)

31. A valve for an internal urinary catheter, comprising:
-
a passage for urine flow; a valve passage positioned along said passage and having at least a portion which is moveably positioned between a substantially blocked position and a flow position; and means for moving said portion, said means for moving being biased toward a blocking position wherein said portion is in said substantially blocked position and flow through said valve passage is substantially blocked, and said means for moving being movable to a released position at least partially moving said portion toward said flow position wherein flow through said valve passage is allowed, wherein said portion comprises a compressible tube, and wherein said means for moving comprises means for releasably compressing said tube in said substantially blocked position, said means for releasably compressing being positionable to said released position wherein compression of said tube is at least partially released. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A valve for an internal urinary catheter, comprising:
-
a passage for urine flow; a valve passage positioned along said passage and having at least a portion which is moveably positioned between a substantially blocked position and a flow position; and means for moving said portion, said means for moving being biased toward a blocking position wherein said portion is in said substantially blocked position and flow through said valve passage is substantially blocked, and said means for moving being movable to a released position at least partially moving said portion toward said flow position wherein flow through said valve passage is allowed, wherein said portion comprises a valve passage member having a valve passage defined therein, said valve passage member being movably mounted in said valve means between said blocked position wherein said valve passage is substantially isolated from said urine passage and flow through said valve means is substantially blocked, and said flow position wherein said valve passage is communicated with said urine passage and flow through said valve passage and said valve means is allowed. - View Dependent Claims (45, 46, 47, 48, 49, 51, 52, 53, 54, 55)

50. A method of controlling urine flow in the urethra, comprising the steps of:
-
providing a cannula having a urine passage, an inlet end having a urine inlet, an outlet end having a urine outlet and valve means positioned along said urine passage for limiting flow from said urine inlet to said urine outlet, said valve means comprising a valve passage having at least a portion which is moveably positioned between a substantially blocked position and a flow position, and means for moving said portion, said means for moving being biased toward a blocking position wherein said portion is in said substantially blocked position and flow through said valve means is substantially blocked, and said means for moving being moveable to a released position at least partially moving said portion toward said flow position wherein flow through said valve means is allowed; positioning said cannula in the urethra with said urine inlet in the bladder; and moving said means for moving to said released position so as to allow flow of urine from the bladder through said urine passage and said valve passage to said urine outlet, wherein said portion comprises a compressible tube, and wherein said means for moving comprises means for releasably compressing said tube in said substantially blocked position, said means for releasably compressing being positionable to said released position wherein compression of said tube is at least partially released, whereby said means for releasably compressing is isolated from urine flow through said valve means.
