Embodiment Construction

[0026] Described herein is a device and system for shock wave therapy for the treatment of highly calcified body cavity atherosclerotic vessels. The present invention provides a shock wave generating system as described above. figure 1 A style diagram of the shock wave generating system is presented. The angioplasty balloon 101 can be pressurized with a liquid medium (such as physiological saline or contrast agent), and the electrodes inside the balloon will generate shock waves, which will propagate through the above-mentioned medium to the hard and fragile plaque in the atherosclerotic plaque. on calcium. The electrodes can be arranged at adjacent and opposite positions, as shown at 102 . These electrodes are provided on the elongated member 203 and are connected to the high voltage generator 105 by conductive wires. 106 is the PCB board through the wire. The PCB board determines the output voltage of the high voltage generator.

[0027]In order to generate a shock wave...

Abstract

The invention discloses a shock wave generation system applied to angioplasty. The shock wave generation system applied to angioplasty is provided with an axially extending elongated member with an outer surface; a plurality of wired electrodes arranged in series; at least one non-conductive gap; and a non-conductive member arranged on the at least one non-conductive gap, wherein each of the wireelectrodes is connected to an output terminal of a high-voltage source by a wire extending from one terminal on an outer surface of the elongated member to the wire electrode; and each non-conductivemember has a shape, the configuration of which affects the direction and / or intensity of shock waves generated by arc discharge from the first electrode to the second electrode, or affects the direction and / or intensity of shock waves generated by arc discharge from the second electrode to the first electrode. Calcified plaques in arteries can be effectively crushed, vascular tissue is not damaged, further interventional treatment of the calcified arteries is facilitated, and occurrence of interlayers and restenosis can be reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a shock wave generating system applied to angioplasty. [0002] technical background [0003] Atherosclerosis is a narrowing and hardening of the arteries caused by plaque buildup. The plaque is composed of fibrous tissue, fat, and calcium. Accumulated calcified plaque blocks the normal flow of blood, reducing the supply of oxygen and nutrients to the body. Of particular concern is arterial disease in the arteries that supply blood to key parts of the body, including the brain, heart, and extremities. [0004] The use of shockwave-assisted balloon angioplasty is a treatment for highly calcified plaque. Although traditional balloon angioplasty can expand the lumen space through balloon inflation, it cannot improve vascular compliance, and dissection and restenosis are common intraoperative and postoperative complications, respectively. Embedding shockwave-generating electrodes in...
