Multi-pole synchronous pulmonary artery radiofrequency ablation catheter
First Claim
1. A device for ablating a target tissue of a patient, the device comprising:
- a catheter body comprising a proximal end and a terminal distal end;
an elliptical ring coupled to the terminal distal end of the catheter body, the elliptical ring having a major axis and a minor axis, wherein the minor axis divides the elliptical ring into a first portion and a second portion, the first portion encompassing an apex of the major axis; and
a plurality of electrodes supported by the elliptical ring,wherein a number of the plurality of electrodes supported by the first portion of the elliptical ring exceeds a number of the plurality of electrodes supported by the second portion of the elliptical ring, andwherein at least one electrode of the plurality of electrodes is disposed over the apex of the major axis.

Abstract
A multi-pole synchronous pulmonary artery radiofrequency ablation catheter may comprise a control handle, a catheter body and an annular ring. One end of the catheter body may be flexible, and the flexible end of the catheter body may be connected to the annular ring. The other end of the catheter body may be connected to the control handle. A shape memory wire may be arranged in the annular ring. One end of the shape memory wire may extend to an end of the annular ring and the other end of the shape memory wire may pass through a root of the annular ring and be fixed on the flexible end of the catheter body. The annular ring may be provided with an electrode group. The device possesses advantages of simple operation, short operation time and controllable precise ablation. The device can be used to treat pulmonary hypertension with pulmonary denervation.
