Abstract
Abstract A thermotherapy device for treatment of diseased biological tissues such as prostatic tissues. The thermotherapy device includes a primary and at least one secondary cooling and/or radiation shielding lumen. The primary lumen contains an energy source and also carries a cooling fluid. The primary lumen and at least a portion of the the secondary lumen are in fluid communication. An energy shielding fluid can be used in the thermotherapy device to effectively screen energy from normal tissue. <IMAGE>
