Embodiment Construction
[0069] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. For ease of description, in the present invention, the end of the device or component that is close to the user (or handle) or away from the nerve site that needs to be adjusted is called "proximal end", and the end of the device or component that is far away from the user (or handle) or close to The end of the neural site that needs to be modulated is called the "distal end".
[0070] Nerve regulation in the present invention refers to removing or reducing the activation of said nerves by means of injury or non-injury. Figure 1-Figure 4 A preferred embodiment of the device for regulating nerves provided by the present invention and its use method is shown. This specific embodiment takes a device for regulating human renal nerves as an example.
[0071] Figure 1-Figure 2 The relevant tissues and structures of the human kidney are shown. Suc...

The invention discloses a catheter device used for regulating nerves. The catheter device comprises a regulation assembly used for regulating the nerves, and further comprises a conveying part used for conveying the regulation assembly to a position close to the nerves and a sheath tube used for sleeving the conveying part, wherein the regulation assembly comprises at least two electrodes used for transmitting regulation energy to the nerves and an electrode bearing part used for bearing the electrodes; the electrodes are connected with lead wires used for conveying the regulation energy; the electrode bearing part comprises an axial filament and an insulating sheath; the axial filament is positioned in a cavity of the insulating sheath; the insulating sheath is sleeved with the electrodes. The electrode bearing part has a first shape and a second shape; when the electrode bearing part is in the first shape, the regulation assembly is suitable for moving in blood vessels; when the electrode bearing part is in the second shape, the electrodes on the electrode bearing part is in a position suitable for transmitting the regulation energy to the nerves.
Description
technical field [0001] The present invention relates to electrosurgery, and more particularly to a catheter device for modulating nerves. Background technique [0002] Refractory hypertension, high blood pressure (sBP ≥ 160mmHg) that is difficult to control even after using 3 or more drugs (all of which have used a diuretic), is relatively common in clinical practice, with many pathogenic factors and unclear pathogenesis. The treatment effect is very poor, and the diagnosis and treatment techniques are still immature, which has become one of the major problems in the treatment of hypertension. [0003] The latest animal and clinical experimental data prove that the regulation of renal nerves (such as denervation) can significantly and permanently reduce resistant hypertension, such as the recently developed radiofrequency ablation of renal arteries. Renal artery radiofrequency ablation is an interventional technique that achieves denervation by sending an electrode catheter...
