摘要： An indwelling catheter for insertion into a patient's urinary tract is provided that includes first and second tubular members that enable drainage of physiological fluids. An inflatable balloon is attached to the second tubular member. The first and second tubular members are interconnected by a connecting tube forming a gap between the first and second tubular members. The connecting tube is in fluid communication with the balloon to enable the balloon to be inflated via the connecting tube. When the balloon is anchored within the urinary bladder the second tubular member is located within the prostatic urethra with one end in close proximity to the sphincter and the other end protruding into the urinary bladder. The first tubular member is located within the penile urethra with one end in close proximity to the sphincter so that the connecting tube traverses the sphincter permitting voluntary control of the sphincter.

摘要： Thermal treatment apparatus for thermally treating selected tissues of a subject located in or near a body cavity, includes a catheter insertable into the subject's body cavity and having a proximal end formed with an inflatable anchoring section for anchoring the catheter in the body cavity, a distal end to be located externally of the body cavity, and an inflatable heating section adjacent the proximal end to be located near the tissue to be heated. The catheter is formed with passageways extending from the distal end to the inflatable heating section for circulating heated fluid through the inflatable heating section but not through the inflatable anchoring section, and a further passageway from the distal end to the inflatable anchoring section for inflating the inflatable anchoring section with a non-heated fluid. The inflatable heating section and the tissue in its proximity may thus be heated to a desired high temperature without correspondingly heating the inflatable anchoring section and the tissue in its proximity.
