Abstract

A focused ultrasound ablation device includes an ultrasound emitting member and a handle shaft having a distal end at which the ultrasound emitting member is disposed. The handle shaft is malleable to permit selective, manual shaping of the handle shaft to access a selected anatomical operative site from a remote location and/or to orient the ultrasound emitting member for contact with anatomical tissue at the selected operative site. A method of thermally ablating anatomical tissue includes the steps of manually shaping a malleable handle shaft to orient an active face of an ultrasound emitting member at a distal end of the shaft to contact anatomical tissue at a selected operative site, positioning the active face against the anatomical tissue at the operative site while a proximal end of the handle shaft is disposed at a remote location; emitting ultrasound energy from the ultrasound emitting member; focusing the ultrasound energy at one or more focusing zones within a target area in the tissue and located a predetermined distance in front of the active face and heating the tissue at the target area with the focused ultrasound energy to create a lesion.
