  • a support tube having a longitudinal central passageway;

    a power lead for providing power and said power lead channeled through said longitudinal central passageway;

    an ultrasound crystal disposed around at least part of said support tube and said ultrasound crystal coupled to said power lead which provides the power to energize said ultrasound crystal and generate ultrasound energy providing thermal therapy to the prostate gland, said ultrasound crystal further including means for inactivating selected portions of said ultrasound crystal for reducing ultrasound energy directed to the rectal wall of the patient; and

    a sealant disposed in contact with said ultrasound crystal allowing vibration necessary for efficient ultrasound energy radiation for the thermal therapy to the prostate gland.
