Abstract:
1. A device for the drainage of urine from a bladder to a position in a urethra past an obstruction of the urethra and then on through the urethra to an outside opening of the urethra at the outside of the human body, comprising: an elongated drainage body having a slit extending in a longitudinal direction along the drainage body, the slit having a length in the longitudinal direction of the drainage body exceeding the distance between the bladder and the obstruction of the urethra; the drainage body assuming a first contracted position taken up within the bladder and assuming a second partially extended position extending from within the bladder into the urethra and past the obstruction; a thread having a length sufficient to extend between at least the bladder and the outside opening, the thread connected to a first end of the drainage body to extend the drainage body from the first position to the second position upon exerting a pulling force on the thread to move the drainage body from the contracted position to the partially extended position; the slit of the drainage body in the second partially extended position extending from within the bladder into the urethra and downstream past the obstruction; and the drainage body returning to the first position upon the release of the pulling force on the thread.
