Abstract
A renal denervation system includes an ablation catheter and an inflation balloon. The renal denervation catheter is insertable into a renal artery to perform a renal denervation procedure. The inflation balloon is inflatable within the renal artery, wherein one of a blood pressure condition in the renal artery resulting from operation of the inflation balloon and a performance characteristic of the inflation balloon indicates efficacy of the renal denervation procedure.
Claims10
A renal denervation system, comprising:
- an ablation catheter insertable into a renal artery to perform a renal denervation procedure including ablating a renal artery;
- an inflation balloon inflatable within the renal artery, wherein one of a decay of a blood pressure condition in the renal artery resulting from operation of the inflation balloon and a performance characteristic of the inflation balloon indicates efficacy of the renal denervation procedure, wherein the decay of the blood pressure condition is measured before and after ablating the renal artery to detect a change in the decay of the blood pressure condition.
An inflation balloon configured to be inflated within a renal artery as part of a renal denervation procedure including ablating the renal artery, wherein one of a decay of a blood pressure condition in the renal artery resulting from operation of the inflation balloon and a performance characteristic of the inflation balloon indicates efficacy of the renal denervation procedure, and wherein the decay of the blood pressure condition is measured before and after ablating the renal artery to detect a change in the decay of the blood pressure condition.
