Problems solved by technology

While discharging the adherent tissue, the ring electrode will also heat the blood in contact with the other side. The flow of blood will not only take away the ablation heat and reduce the ablation effect, but also easily form scabs and thrombus after the blood is heated, resulting in related complications

Embodiment Construction

[0023] Combine below figure 1 Specific embodiments of the present invention will be described in detail. For ease of description, the end close to the control handle, that is, the operator or away from the kidney is called "proximal end", and the end far away from the control handle, that is, the operator, or near the kidney is called "distal end".

[0024] According to the present invention, the multi-pole electrode catheter for thermally induced renal neuromodulation comprises: a control handle (not shown in the figure); The control handle, the other end (distal end) of the catheter tube body 1 is closed; and a plurality of point-shaped electrodes 3 arranged in a staggered manner fixed on the other end (distal end) of the catheter tube body 1 , each point electrode 3 can be used to extract electrical signals and ablate, each electrode 3 is connected with a wire (not shown in the figure), and the wire extends through the cavity of the catheter tube body 1 to the Connect the...

Abstract

A multi-pole electrode catheter for heat-induced renal nerve regulation, comprising: a control handle; a catheter body, one end of the catheter body is fixed to the control handle, and the other end of the catheter body is closed; it is fixed on the catheter body On the other end of the catheter, multiple point-like electrodes are arranged in a staggered manner, each electrode can be used to extract electrical signals and ablate, each electrode is connected with a wire, and the wire extends through the cavity of the catheter tube body to the control handle , so as to be electrically connected with the control handle. The multi-pole point-shaped electrode catheter only heats the adherent tissue with radiofrequency and does not heat the blood.

Description

technical field [0001] The invention relates to an electrode guide, in particular to an electrode guide for heat-induced renal nerve regulation. Background technique [0002] The latest research shows that hypertension is related to the high excitability of renal sympathetic nerves in patients. Blocking renal sympathetic nerves can effectively treat intractable hypertension that is ineffective in drug treatment. Catheter radiofrequency ablation of renal sympathetic nerve heating is an ideal method to weaken its activity or even lose its conduction function, and this method has the characteristics of minimally invasive intervention, no side effects, few complications, and rapid recovery. [0003] Simple, safe and reliable catheter devices dedicated to radiofrequency ablation of renal sympathetic nerves are not yet mature. It has been reported in related literature or patents that it is used for renal artery sympathetic nerve radiofrequency heating devices, but there is still...
