Abstract

The invention provides a discharge-controllable shock wave balloon catheter system which comprises a shock wave treatment host, a balloon, a catheter and a plurality of electrode pairs, wherein one end of the catheter penetrates through the balloon; the other end of the catheter is connected with the shock wave treatment host, and the electrode pair is contained in the balloon and installed on the catheter. The shock wave treatment host comprises a plurality of pulse switch modules, the single electrode pairs are electrically connected with the single pulse switch modules in a one-to-one correspondence mode, or the plurality of electrode pairs are independently electrically connected with the same pulse switch module. According to the shock wave balloon catheter system, by arranging the electrode pairs of different sizes, precise treatment of calcified blood vessels can be achieved easily; herein, the multiple electrode pairs are not connected in series, the magnitude and frequency of shock wave energy released by each electrode pair can be independently controlled, synchronous high-voltage pulse discharge can be achieved and asynchronous high-voltage pulse discharge can also be achieved, so that the flexibility of a discharge control mechanism is improved, the discharge efficiency is improved, and the surgical treatment time of vascular calcification is shortened.

Description

technical field [0001] The present application belongs to the technical field of vascular calcification lesion treatment equipment, and more specifically relates to a shock wave balloon catheter system with controllable discharge. 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 un...
