Embodiment Construction
[0023] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0024] figure 1 Shown is a schematic structural view of the balloon-expandable renal artery sympathetic nerve ablation catheter of the present invention. The balloon-expandable renal artery sympathetic nerve ablation catheter includes a helical electrode 2, a balloon 1, an outer tube 6 and a functional handle 7. The helical electrodes 2 are a pair of parallel electrodes, which are continuous but not on a circle and axially projected as Closed ring, during ablation, the electrode pair releases ablation energy to ablate the vascular tissue between the electrode pairs. Because the ablation area is continuous, it can completely isolate the sympathetic nerve ...
