A thermotherapy device for treatment of diseased biological tissues. The thermotherapy device includes a primary and at least one secondary cooling and/or radiation shielding lumen. The lumens are connected or disposed adjacent one another along their longitudinal exterior walls. An energy source is insertable into one or more of the cooling lumens to carry out a heating protocol to treat the diseased tissue while screening and/or cooling normal tissue. A transrectal ultrasound positioning and temperature sensing device can control the energy source for effective treatment.

Thermotherapy probe

A method of providing thermal therapy to prostate tissue of a patient. The method includes: inserting a mechanical separator or infusing a fluid to separate human tissue to be treated from nontarget tissue, thereby providing thermal insulation and other beneficial effects, and applying the thermal therapy to the target tissue.

Organ separation for thermal therapy

A method for performing thermotherapy treatment of patient prostate tissue, comprising the steps of inserting a thermotherapy probe in a urethral passageway, the probe having a fluid volume containing portion and an energy source inserted therein for generating radiation to heat the patient prostate tissue by the tissue absorbing the radiation; generating a pressurized fluid flow in the probe within the fluid volume containing portion and cooling the energy source by enveloping at least a portion of the energy source to direct the pressurized fluid flow to come into direct contact with and circulate around and over all energy radiating portions of the energy source simultaneously with energy radiation by the energy source, thereby preventing thereby preventing thermal damage to the energy source; and providing an inflatable nondistensible structure as part of the probe inserted into the urethral passageway and inflating the nondistensible structure with the pressurized fluid flow to cool tissue contacting the nondistensible structure simultaneously with energy radiation by the energy source, thereby controlling pain caused by heating localized areas of the tissue contacting the nondistensible structure, and the nondistensible structure upon inflating causing straightening along a longitudinal axis of the treated patient prostate tissue and the straightening enabling greater uniformity and effectiveness of treatment of the prostate tissue.
