    • Method and Device for thermal treatment of tissue within a living body. Device comprises a housing extending from a distal end to a proximal end. The housing includes a first opening exposing an inner chamber of Device to the fluid. The housing is sized and shaped for insertion to a target location within the body and a piezoelectric element fixed within the housing and generating pulses of ultrasound energy directed substantially along a longitudinal axis of the housing in combination with first and second deflecting elements ("FDE" and "SDE"). FDE is mounted within the housing on a distal side of the piezoelectric element. SDE is mounted within the housing on a proximal side of the piezoelectric element. FDE and SDE deflect a portion of ultrasound energy from the piezoelectric element away from the axis so that the deflected ultrasound energy exits the housing via the first opening.
    • 用于热处理生物体内组织的方法和装置。 装置包括从远端延伸到近端的壳体。 壳体包括将Device的内腔暴露于流体的第一开口。 壳体的尺寸和形状适于插入到主体内的目标位置和固定在壳体内的压电元件,并且产生基本上沿着壳体的纵向轴线指向的第一和第二偏转元件(“FDE” 和“SDE”)。 FDE安装在壳体内的压电元件的远端侧。 SDE安装在壳体内的压电元件的近侧。 FDE和SDE将来自压电元件的超声能量的一部分偏离轴线,使得偏转的超声能量经由第一开口离开壳体。
