    摘要： A catheter apparatus comprises an elongated catheter body having a distal end, a proximal end, and at least one fluid lumen extending longitudinally therein; and a plurality of flexible electrode segments on a distal portion of the catheter body adjacent the distal end, each pair of neighboring flexible electrode segments being spaced from each other longitudinally by a corresponding electrically nonconductive segment. Each flexible electrode segment comprises a sidewall provided with one or more elongated stiffness reductions extending through the sidewall, the one or more elongated stiffness reductions providing flexibility in the sidewall for bending movement relative to a longitudinal axis of the catheter body. The electrically nonconductive segment is substantially smaller in length than each of the corresponding pair of neighboring flexible electrode segments.

    摘要： A method for denervation comprises introducing a distal portion of a catheter through an interior of a vessel of a patient to a location at or proximate one of a renal pelvis or a calyx. The catheter includes an elongated catheter body extending longitudinally between a proximal end and a distal end. The catheter body includes the distal portion at the distal end and a catheter lumen from the proximal end to the distal end. Energy is delivered from the distal portion to cause renal denervation, for example, by denervating at least some tissue proximate at least one of the renal pelvis or a renal vessel from a location at or proximate the renal pelvis or the calyx from a location at or proximate the calyx.

    摘要： In one embodiment, an irrigated catheter ablation apparatus comprises an elongated body having a distal end, a proximal end, and at least one fluid lumen extending longitudinally therein; and a plurality of segmented ablation electrodes on a distal portion of the elongated body. The electrodes are spaced from the proximal end and from the distal end of the elongated body by electrically nonconductive segments. The electrodes are spaced from each other longitudinally by electrically nonconductive segments. For each electrode that is longitudinally disposed next to one of the nonconductive segments, an edge is formed between an electrode end of the electrode and a nonconductive segment end of the nonconductive segment. A plurality of elution holes are disposed adjacent to the edges. A plurality of ducts establish fluid communication between the elution holes and the fluid lumen.

    摘要： An ablation apparatus comprises an ultrasonic transducer which includes a piezoelectric element having a cylindrical shape; a plurality of external electrodes disposed on the outer surface of the piezoelectric element; and at least one internal electrode disposed on the inner surface of the piezoelectric element. The at least one internal electrode provides corresponding internal electrode portions that are disposed opposite the external electrodes with respect to the piezoelectric element, the external electrodes and the at least one internal electrode to be energized to apply an electric field across the piezoelectric element. The ultrasonic ablation zones of the external electrodes are distributed in a staggered configuration so as to span one or more open arc segments around the longitudinal axis, and the ultrasound ablation zones of all external electrodes projected longitudinally onto any lateral plane which is perpendicular to the longitudinal axis span a substantially closed loop around the longitudinal axis.
