Abstract
A device for maintaining a passage through the prostate gland (13) after treatment of a catheter (10) inserted through the urethra into the prostate gland, the catheter (10) being provided with means (11) for heating the prostate gland. A sleeve (12) is received over the catheter (10) so as to follow the catheter (10) during insertion into a desired position within the prostate gland, and the sleeve (12) is formed to remain in the desired position when the catheter is removed from the prostate gland, thereby maintaining a passage having a predetermined lower inner diameter through the prostate gland when tissue in the prostate gland swells.
