Abstract

A bulking agent is accurately administered into body tissue surrounding the urethra of a patient to support a urinary sphincter muscle and facilitate enhanced control over urination. Preferably, the bulking agent is inserted by use of a catheter which is anchored with a balloon in the bladder. The balloon contacts the bladder neck and locates the position of a needle which is extended from the catheter into the tissue. Consequently, the bulking agent is injected at a position relative to the bladder neck which is very effective in supporting the sphincter muscle. The catheter is rotated in rotational increments to introduce the bulking agent in multiple positions in an annular ring surrounding the urethra.
