On April 30, the National Medical Products Administration approved Medtronic's innovative product registration applications for the "Single-Use Multi-Pole Renal Artery Radiofrequency Ablation Catheter" and the "Renal Artery Radiofrequency Ablation Generator."

The disposable multi-pole renal artery radiofrequency ablation catheter consists of an electrode array, catheter, catheter handle, catheter connection cable, and straightening tool. The renal artery radiofrequency ablation instrument consists of a generator, remote control, power cord, and DVI-D cable.

The above two products are used together. The radiofrequency ablation instrument can transmit radiofrequency energy through the catheter electrode to the intima of the renal artery. Using the thermal effect of the current, it deactivates the sympathetic nerves around the renal artery, blocks the excitation conduction of the sympathetic nerves, and achieves the purpose of reducing the patient's blood pressure.

This product lowers blood pressure by physically blocking the transmission of sympathetic nerve excitement. Compared with traditional drug treatments, it can effectively avoid the influence of factors such as patient compliance and drug half-life, providing a new auxiliary treatment option for patients with refractory hypertension.
