ABSTRACT:
A device for thermal ablation therapy having a handle sized and shaped to be held by a user, one or more transducer assembly which, when activated, emits ultrasound energy capable of heating tissue and which is movably mounted relative to said handle element, and moving means, such as one or more rods, for moving the transducer assembly or assemblies, while activated, to any one of a plurality of positions relative to the handle element and relative to tissue to be ablated, whereby ultrasound energy is efficiently delivered to the tissue. The device also includes carrying means, such as a shaft attached at one end to the handle element, which carries the rod or rods and the transducer assembly or assemblies. The rod or rods are engaged with a knob positioned in the handle and when the knob is rotated, the rod or rods are rotated, thereby causing the transducer assembly or assemblies to move relative to the handle, the shaft and the tissue to be ablated.
