1. A device for maintaining a passage through a prostate gland said device comprising:
- a catheter adapted to be inserted through an urethra to a prostate gland;
heating means for providing heat treatment of tissue of the prostate gland for accomplishing dead tissue, said heating means being provided in the catheter; and
a sleeve received over the catheter to follow the catheter during insertion of the catheter through the urethra into a desired position within the prostate gland, said sleeve being formed with an outer diameter that is larger than an inner diameter of the urethra to allow the sleeve to remain in said desired position during said heat treatment and 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 within the prostate gland is swollen as a result of said heat treatment.

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.

7. A device for maintaining a passage through a prostate gland said device comprising:
-
a catheter adapted to be inserted through an urethra to a prostate gland; heating means for providing heat treatment of tissue of the prostate gland for accomplishing dead tissue, said heating means being provided in the catheter; and a sleeve received over the catheter to follow the catheter during insertion of the catheter through the urethra into a desired position within the prostate gland, said sleeve being formed with openings to allow passage of dead tissue after said heat treatment and being formed with an outer diameter that is larger than an inner diameter of the urethra to allow the stent to remain in said desired position during said heat treatment and 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 within the prostate gland is swollen as a result of said heat treatment.
