Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In this application, "shock wave" is a general term for various forms of waves (such as pressure waves, etc.) that can be generated by the electrode assembly during discharge, and is not used to limit specific wave forms.

[0038] In this application, the "distal end" or "end" of a component such as a shock wave device or electrode assembly refers to the end toward the tip of the lead that enters the subject during surgery, while the "proxim...

Abstract

The present invention provides an electrode assembly for a shock wave device, the electrode assembly being provided inside a balloon of the shock wave device, the electrode assembly comprising: a first insulating layer having an elongated hollow structure; an inner electrode; the inner electrode is positioned in the first insulating layer; a first conductor provided on at least a portion of an outer peripheral surface of a tip of the first insulating layer; and an external electrode disposed on at least a portion of an outer peripheral surface of a base end of the first insulating layer such that an insulating gap is formed between the external electrode and the first conductor. According to the electrode assembly, attenuation of shock waves in the conduction process can be effectively reduced, the service life of the electrode assembly can be effectively prolonged, and therefore the satisfactory treatment effect can be safely and reliably achieved.

Description

technical field [0001] The invention belongs to the field of medical technology, and particularly relates to an electrode for a shock wave device for treating heart valve or blood vessel calcification, a shock wave device using the electrode, and a method for treating animal heart valve or blood vessel calcification. Background technique [0002] Heart valve calcification is the main pathological manifestation of heart valve stenosis and regurgitation, which usually occurs in the elderly; vascular calcification is a common common cause of atherosclerosis, hypertension, diabetic vascular disease, vascular damage, chronic kidney disease and aging. pathological manifestations. [0003] At present, shock wave balloon technology has been used to treat heart valve or vascular calcification due to its advantages of easy operation and balloon pre-dilation. like figure 1 As shown, the prior art shock wave device 900 for treating heart valve calcification includes a shock wave trans...
