Problems solved by technology

[0006] However, when dealing with calcified lesions, there is still a problem with shock wave or pressure wave balloons. For lesions with severe stenosis or complete occlusion, the shock wave or pressure wave balloon may not be able to pass through the lesion, making the operation impossible.

Embodiment 1

[0050] see Figure 4 (The schematic diagram only describes the electrode structure, and does not mark other parts of the balloon catheter, nor does it mark the wires and the control host 9). The pressure wave balloon catheter provided by the application includes a working balloon 1, and the working balloon 1 is equipped There are multiple working electrode units 3 , and each working electrode unit 3 includes a main electrode pair 31 and a secondary electrode pair 32 . In clinical use, the operation control host 9 activates the "normal mode", and the second control device 92 controls all main electrode pairs 31 to release pulse voltages to generate pressure waves, eliminate calcified plaques in blood vessels, and achieve therapeutic purposes. If you encounter stubborn calcified plaque, when the number of pulses of the main electrode pair 31 has reached the upper limit and cannot completely eliminate the calcified plaque, the operation control host 9 starts the "standby mode". I...

Embodiment 2

[0052] see figure 1 (The schematic diagram only describes the electrode structure, and does not mark other parts of the balloon catheter, nor does it mark the wire and the control host 9). The pressure wave balloon catheter provided by the application includes a working balloon 1 and an opening balloon 2. The balloon 2 is arranged at the front end of the balloon catheter, and the tip electrode pair 41 is arranged inside the opening balloon 2; a plurality of working electrode units 3 are arranged inside the working balloon 1, and each working electrode unit 3 includes a main electrode pair 31. In clinical use, in the face of clinical severe stenosis or complete occlusion of blood vessels, the opening balloon 2 is placed close to the stenosis or occlusion site, and the control host 9 is operated to turn on the "through mode", and the first control device 91 activates the head end The pulse voltage of the electrode pair 41 generates a pressure wave, thereby gradually opening the...

Embodiment 3

[0054] see Figure 6 (The schematic diagram only describes the electrode structure, and does not mark other parts of the balloon catheter, nor does it mark the wire and the control host 9).

Abstract

The invention belongs to the technical field of medical instruments, and provides a pressure wave balloon catheter which is provided with a working balloon used for expanding a diseased region and anopening balloon used for opening the diseased region of a blood vessel, and the working balloon and the opening balloon are adjacently arranged. At least one working electrode unit capable of generating pulse pressure waves is arranged in the working balloon; the opening balloon is arranged at the front end of the balloon catheter, at least one opening electrode unit is arranged in the opening balloon, and each opening electrode unit comprises a head end electrode pair and an output mechanism used for limiting the output direction of pulse pressure waves generated by the head end electrode pair. The structure of the pressure wave balloon catheter is improved, the passing ability of the balloon catheter in a blood vessel is ensured, and an operation can be normally carried out.

Description

technical field [0001] The present application belongs to the technical field of medical devices, and more specifically relates to a pressure wave balloon catheter. Background technique [0002] Cardiovascular disease has always been one of the important causes of death in the world, and the development of medical knowledge and technology in the past half century has greatly reduced the mortality rate related to cardiovascular disease. Among them, balloon dilatation angioplasty has played an important role in reducing the morbidity and mortality of obstructive coronary artery disease, and has become the most common way to treat coronary heart disease in all countries in the world; at the same time, balloon dilation angioplasty Surgery is also the main modality of revascularization in patients with peripheral arterial disease. [0003] For traditional catheter-based interventional therapy techniques, percutaneous balloon angioplasty (PTA) is usually used clinically to open c...
