Abstract
A device for heat treatment of prostate, comprising a treatment catheter with a fluid reservoir and heating means which is arranged within the treatment catheter and emits electromagnetic radiation for heating of the surrounding bodily tissue. The fluid reservoir constitutes an integrated part of the catheter for treatment and is positioned in the catheter so that, when inserted in a patient, it extends to cover the area heated by the heating means between the prostatic apex and bladder neck. The fluid reservoir also constitutes a closed chamber which is connectable via a channel passing through the catheter for treatment. A stop for the heat-absorbing means is embodied distal to said heating means and distal to said heat reservoir.
