Abstract

The invention provides a pressure wave balloon catheter. The pressure wave balloon catheter comprises a catheter, a balloon, a first conductor, a second conductor and a wire. The balloon is arranged at the front end of the catheter, a closed space is formed by the balloon and the peripheral wall of the catheter, and the balloon is driven by the catheter to extend into vascular tissue; the peripheral wall, located in the balloon, of the catheter sinks inwards to form a mounting groove; or the first conductor wraps the peripheral wall of the catheter, the first conductor and the second conductor are connected to the pulse circuit in series through a wire, the first conductor wraps the bottom wall of the mounting groove, the second conductor is located on one side of the first conductor, a communication channel is formed between the first conductor and the second conductor, the communication channel is used for communicating the first conductor and the second conductor to form an electrode; the electrode is used for generating pressure waves in the balloon under the pulse voltage. According to the pressure wave balloon catheter provided by the invention, the section size of the balloon catheter can be reduced, and the trafficability of the balloon in vascular tissues can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a pressure wave balloon catheter. Background technique [0002] Cardiovascular disease has always been one of the important factors of death in the world. In the past half century, with the development of medical knowledge and medical technology, the mortality rate of cardiovascular disease has been greatly reduced. Among these, balloon dilation angioplasty has played an important role in reducing morbidity and mortality from obstructive tubular artery disease. Traditional catheter-based interventional therapy usually uses percutaneous balloon angioplasty (Percutaneous transluminal angioplasty, PTA) to open calcified lesions in arterial and venous vessels. When the balloon is inflated to dilate the calcified lesion in the vessel wall, the balloon gradually releases the pressure until the calcified lesion ruptures; but at the same time, the pressure built up i...
