The present disclosure provides an improved ablation catheter. In particular, the present disclosure provides an improved renal denervation ablation catheter and system including a catheter handle and a means for tracking, monitoring, and/or recording the circumferential angular history of the renal denervation ablation catheter handle. The renal denervation ablation catheters in accordance with the present disclosure are well-suited for use with a renal denervation ablation system that can record the circumferential angular history of the renal denervation catheter handle, and hence the circumferential angular ablation history of the catheter electrode within a vessel, and use this data in combination with other known information to estimate the percent circumferential denervation of the vessel.
An ablation catheter system comprising a catheter handle, an elongate catheter body, an electrode, and a means for tracking a circumferential rotational history of the catheter handle.
A method for tracking the circumferential ablation history of a renal artery, the method comprising ablating at least two areas on the renal artery using an ablation system comprising an ablation catheter comprising a catheter handle, an elongate catheter body, an electrode, and a means for tracking a circumferential rotational history of the catheter handle, and recording the circumferential rotational history of the catheter handle for each ablation.
A method for estimating the circumferential percent renal denervation for a renal artery, the method comprising performing at least two ablations on the renal artery using an ablation system comprising an ablation catheter comprising a catheter handle, an elongate catheter body, an electrode, and a means for recording a circumferential rotational history of the catheter handle, recording a circumferential angle for each ablation, and using an average ablation spot size, a diameter of the artery, and circumferential angle for each ablation to estimate the circumferential percent renal denervation for the artery.
