Abstract
Transurethral systems and methods for delivering electrical energy and controlled, mild heating to a prostate tissue of a patient for destruction of cancerous and/or hyperplastic tissue. A method includes positioning an elongate urethral probe having an expandable member with electrode elements at a target location in the patient's urethra, and inflating or expanding at the target location. Secondary electrodes are positioned within or adjacent to the prostate tissue and spaced from the electrode elements of the expandable member, and an alternating electrical current flow is established between the electrode elements of the expandable member and the one or more secondary electrodes. Current delivery can be selected so as to destroy or ablate cancerous cells of the prostate tissue.
