Abstract

A renal denervation system includes a renal denervation catheter and a flow determining system. The renal denervation catheter includes a plurality of ablation members positioned at a distal end portion thereof. The renal denervation catheter is insertable into a renal artery. The flow determining system includes a processor and first and second flow determining members spaced apart on the renal denervation catheter. The processor is configured to determine a change in blood flow through the renal artery resulting from a renal denervation procedure using the renal denervation catheter in response to input from the first and second flow determining members.
