Method for valving body fluids
First Claim
1. A method for achieving urinary continence, comprising the steps of:
- inserting a collapsible valving member into a first position in the urethra proximate the bladder, the valving member including means for directing urine flow from the bladder through an expanding valve;
expanding said valve outwardly when said valving member is in said first position so as to substantially halt the flow of urine from the bladder; and
selectively contracting said valve to allow urination.

Abstract
A method and apparatus for valving body fluids involving a flexible tubular body with a drainage canal therethrough, including collapsible means for blocking the passageway and thereby preventing the flow of urine. The length of the device is such that one end protrudes into the bladder and the other end terminates interior of the meatus. The device includes a means for anchoring to secure it in place and a plug device for deflating and releasing the anchoring means and for collapsing the blocking means to facilitate removal of the device from the body. The device is manually actuable to an open position and means are provided to delay the closing of the device for a sufficient period of time to allow voiding of the bladder. The collapsible and expandable nature of the device facilitates its insertion and removal, particularly while passing through areas of restricted diameter.

8. A method for achieving urinary continence, comprising the steps of:
-
collapsing a valve member from its normal shape for insertion through areas of restricted diameter, the valve member being coupled to a longitudinal body having a flow passage; inserting said valve member and said body into a position in the urethra proximate the bladder, the body protruding into the bladder; allowing an outer portion of said valve member to automatically expand to its normal shape to increase the flow area therethrough; expanding an inner portion of said valve member against the outer portion so as to substantially halt the flow of urine through the flow passage; and selectively compressing said inner portion of said valve member to allow the flow of urine from the bladder through the flow passage. - View Dependent Claims (9, 10, 11)
