摘要

A renal denervation catheter includes a catheter shaft, at least one ablation member, and a sensor, and is operable to perform a renal denervation procedure. The catheter shaft includes a distal end portion insertable into a renal artery. The at least one ablation member is positioned at the distal end portion of the catheter shaft and operable to ablate renal nerves along a wall of the renal artery. The sensor provides information that correlates to blood flow in the renal artery. A change in blood flow rate in the renal artery resulting from the ablation is indicative of the efficacy of the renal denervation procedure.
