Patent ID: 7662145

Claim:
A method of draining urine in a urethra of a male human from the bladder through the prostate gland and through the orifice in the external urinary sphincter muscle and into the urinary canal which ends at an exterior opening, the urine flowing from a distal location at the bladder to a proximal location at the exterior opening, the method comprising: positioning a partial-length indwelling catheter in a normal position in which a distal end of the catheter is located within the bladder and a proximal end of the catheter is located within the prostatic urethra at position distal of the external urinary sphincter muscle; anchoring the catheter to resist proximal movement of the catheter from the normal position by inflating an inflatable balloon on the distal end of the catheter within the bladder and contacting the inflated balloon with the bladder neck adjacent to the opening from the bladder into the prostatic urethra; extending an inflation tube from the catheter through the orifice of the external urinary sphincter muscle and through the urinary canal and out the exterior opening while the catheter is in the normal position; inflating the balloon by delivering fluid through the inflation tube into the balloon; anchoring the catheter to resist distal movement from the normal position with the inflation tube extending within the urinary canal; selectively displacing the proximal end of the catheter in a proximal direction from the normal position through the orifice of the external urinary sphincter muscle to initiate conducting urine from the bladder through an interior passageway of the catheter which extends between the distal end and the proximal end and into the urinary canal to drain urine from the bladder; and selectively displacing the proximal end of the catheter in the distal direction to remove the proximal end of the catheter from within the orifice of the external urinary sphincter muscle to the normal position to conclude conducting urine from the bladder through the interior passageway into the urinary canal.
