Abstract

The invention provides an electrode component and an electrode balloon catheter. The electrode component comprises a first electrode, a second electrode and an accommodating structure, the accommodating structure is arranged on the first electrode, at least part of the second electrode is arranged in the accommodating structure, and the first electrode and the second electrode are arranged at an interval; one of the first electrode and the second electrode is a positive electrode, and the other one is a negative electrode; the first electrode and the second electrode are used for being electrically connected with a high-voltage generating and processing device. By means of the arrangement, the electrode components are arranged in a single layer, the passing size of the electrode balloon catheter is reduced, the passing size of the electrode balloon catheter is thinner and closer to the size of a pre-expanded balloon, and the phenomenon that the electrode balloon catheter is difficult to pass or even broken during intervention is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrode component and an electrode balloon catheter. Background technique [0002] Angioplasty is a surgical method that uses mechanical methods to restore the narrowed vessel cavity to its original size. Traditional angioplasty often uses a balloon catheter to physically dilate the narrowed lesion to re-open the vessel. However, when the balloon is expanded, it is easy to cause tearing of the adventitia of the vessel. The method of indirectly crushing calcified deposits or "stones" in the urinary tract or biliary tract by using the electrohydraulic effect can be used to destroy the calcification structure attached to the diseased blood vessel wall, that is, the electrohydraulic lithotripsy technology can be applied in angioplasty. The principle of electrohydraulic lithotripsy technology is that the liquid rapidly vaporizes under the high-pressure electric field to ...
