Patent ID: 8518016

Claim:
A method of draining urine from a bladder to a position distal of a urinary sphincter muscle in a urinary tract which also includes a urinary canal extending from the sphincter muscle to an exterior opening, comprising: positioning an indwelling catheter having an inflatable balloon in the urinary tract in a use position in which the indwelling catheter extends from the bladder to a position distally adjacent to the sphincter muscle; extending an inflation tube having a coiled section within the urinary tract from the indwelling catheter through the portion of the urinary canal surrounded by the sphincter muscle and out of the exterior opening; inflating the balloon within the bladder by delivering fluid though the inflation tube and into the balloon; retaining the indwelling catheter against proximal movement from the use position by contacting the inflated balloon with the bladder; retaining the indwelling catheter against distal movement from the use position by contacting the coiled section with a constriction of the urinary tract caused by the sphincter muscle at a location proximally adjacent to the constriction; and draining urine through the indwelling catheter from the bladder to a position in the urinary tract distally adjacent to the sphincter muscle.
