Devices for performing thermal ablation having movable ultrasound transducers
First Claim
1. A device for performing thermal ablation therapy, comprisinga handle element sized and shaped to be held by a user;
- at least one transducer assembly which, when activated, emits ultrasound energy capable of heating tissue, said at least one transducer assembly being movably mounted relative to said handle element;
moving means for moving said at least one transducer assembly, while activated, to any one of a plurality of positions relative to said handle element and relative to tissue to be ablated, whereby ultrasound energy is efficiently delivered to the tissue;
a carrying element for carrying said moving means and said at least one transducer assembly, said carrying element being connected at one end to said handle element and having an opposite end located remote from said handle element, said carrying element and said moving means being sized and shaped for at least partial insertion into a patient'"'"'s cavity or luminal structure; and
actuating means for actuating said moving means, said actuating means engaging said moving means and being positioned proximate to said handle element such that said actuating means is manually accessible by a user, said actuating means including a rotatable knob.

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.
