Abstract

The invention provides an ultrasonic wave saccule for cardiovascular system lithotripsy and a saccule duct system. The ultrasonic wave saccule comprises a saccule treatment end and a medicine applyinglayer, wherein the saccule treatment end is provided with an ultrasonic wave receiver and a plurality of monocrystal ultrasonic transducers; the monocrystal ultrasonic transducers are connected withthe ultrasonic generator and can produce ultrasonic waves through energy supplying of the ultrasonic generator; and the medicine applying layer is arranged on the surface of the saccule treatment end.According to the ultrasonic wave saccule disclosed by the invention, the ultrasonic generator is arranged in the saccule; under the impact of the ultrasonic waves, the disintegration of a medicine loading coating can be accelerated, so that the selection range of a carrier of the ultrasonic wave saccule can be wide, and even the carrier which is not liable to disintegrate is selected, the releasing of the medicine can also be completed in a short time.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an ultrasonic balloon and a 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...
