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.
