Estimating the term…
A device for thermal ablation therapy having emitting means for emitting ultrasound energy capable of heating tissue and moving means for moving the emitting means between an undeployed position, in which the emitting means is in a first orientation which facilitates insertion of the device, and a deployed position, in which the emitting means is in a different second orientation that is selected to efficiently deliver ultrasound energy to the tissue to be ablated. The moving means includes one or more movable carriers and the emitting means is one or more piezoelectric transducers that are securely mounted on the carriers for conjoint movement therewith. A method for thermal ablation therapy using ultrasound energy involves positioning an ultrasound device in an undeployed position proximate to tissue to be heated; moving the ultrasound device from its undeployed position to a deployed position; and activating the ultrasound device to emit ultrasound energy for a predetermined period of time.
A device for thermal ablation therapy, comprising emitting means for emitting ultrasound energy capable of heating tissue, said emitting means being movable between an undeployed position, in which said emitting means is in a first orientation which facilitates insertion of said device, and a deployed position, in which said emitting means is in a second orientation, which is different from said first position, said second orientation being selected to efficiently deliver ultrasound energy to tissue to be ablated;
A method for thermal ablation therapy using ultrasound energy, comprising the steps of:
