Embodiment Construction

[0026] The present invention describes devices and systems for treating disease of atherosclerotic vessels with accumulation of highly calcified platelets. The device is a shock wave generating angioplasty catheter system comprising a plurality of electrodes forming a shock wave source disposed along a distal end thereof. figure 1 One such example of a catheter system generating shock waves is shown. It is an enhancement of traditional balloon angioplasty catheters used to treat atherosclerotic arteries in humans. Whereas traditional balloon angioplasty uses an inflated balloon to mechanically compress calcified platelets and dilate the vessel lumen, the catheter of the present invention features the addition of high-coverage, low-profile electrode assemblies that generate shock waves to rupture calcifications. These electrodes are located within an inflatable balloon 101 in the area treated by the catheter and can be connected to an extracorporeal high voltage source by mean...

Abstract

The invention discloses a shock wave generating system for an angioplasty catheter. The system includes an elongate member, wire electrodes, a non-conductive gap, each wire electrode attached to an electrical output terminal of a high voltage power source by an electrical wire extending from a terminal on an outer surface of the elongate member to the wire electrode. The system is an electrode assembly of a shock wave generating angioplasty catheter for treating calcified arteries. Shock waves are impact in nature and can impact and decompose hard calcified platelets deposited on the inner wall of the artery. Once these deposits are fragmented, the space of the arterial lumen expands, thereby improving blood flow.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a high-coverage and low-profile electrode assembly used for an angioplasty shock waveguide. Background technique [0002] Atherosclerosis is the constriction and hardening of arteries due to the accumulation of platelets. This platelet is composed of fibrotic tissue, fat and, as the disease progresses, calcium. This buildup of calcified platelets blocks the normal flow of blood, reducing the supply of oxygen and nutrients to the body. Of particular concern is disease of the arteries that supply blood to key parts of the body, including the brain, heart and extremities. [0003] Angioplasty is a technique that uses an expandable balloon mounted on a catheter to open constricted arteries plagued by platelet buildup. The catheter is inserted percutaneously into the vasculature and the balloon is pressurized to radially compress the calcified platelets. The resulting artery is then...
