Ultrasonic balloon catheter system for cardiovascular lithotripsy

Abstract

The invention provides an ultrasonic balloon catheter system for cardiovascular lithotripsy. The ultrasonic balloon catheter system comprises an ultrasonic generator, a catheter body and a balloon treatment end, wherein one end of the catheter body is connected with the ultrasonic generator; the balloon treatment end is arranged at the end, away from the ultrasonic generator, of the catheter bodyand internally provided with a plurality of monocrystal ultrasonic transducers and an ultrasonic receiver, and the monocrystal ultrasonic transducers are electrically connected with the ultrasonic generator through the catheter body; and the ultrasonic generator is used for transmitting electric energy to the ultrasonic transducers, the monocrystal ultrasonic transducers are used for converting the electric energy into ultrasonic vibration for lithotripsy, and the ultrasonic wave receiver is used for receiving ultrasonic waves and converting the ultrasonic waves into electric signals. The ultrasonic generator of the ultrasonic balloon catheter system transmits the electric energy to the monocrystal ultrasonic transducers and then emits the ultrasonic waves, and relatively uniform impact force is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ultrasonic balloon catheter system for cardiovascular lithotripsy. Background technique [0002] With the aggravation of population aging and the influence of environment, diet, living habits and other factors, the incidence of vascular calcification and / or valve calcification is increasing year by year. When vascular calcification needs to be opened or a film formed by slight calcification needs to be repaired, the conventional method is to pre-expand with an inflatable balloon. This usually requires a lot of pressure, with the internal pressure of the inflated balloon gradually expanding until the pressure inside the balloon ruptures or bursts the calcified lesion, possibly causing damage to the blood vessel. [0003] The foreign SHOCKWAVE MEDICAL company applies the electrohydraulic lithotripsy technology in angioplasty or valvular calcification. Its basic princip...

AI Technical Summary

Problems solved by technology

[0005] Therefore, in order to overcome the problem of uneven impact and the risk of electric leakage in the field of cardiovascular lithotripsy in the prior art, an ultrasonic balloon catheter system that can use ultrasound to uniformly crush lithotripsy in the cardiovascular system is provided.
