Problems solved by technology

However, the thickness of blood vessels in different positions on the same blood vessel in the human body is not the same, and if the shock wave generated by the pulse is too large, it will cause a certain degree of damage to the blood vessel. It has not been used clinically, and at present, how to safely and effectively remove calcified plaques in blood vessels is still a major technical problem

Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0031] see Figure 1 to Figure 5 As shown, an ultrasonic balloon catheter assembly includes a catheter 1 and an inflatable balloon 2 arranged on the catheter 1. The catheter 1 passes through the lumen of the balloon 2 in the axial direction and is used to inject Fluid is passed into the cavity, and the circumference of the balloon 2 is sealed with the catheter 1, and the balloon 2 is inflated after being filled with fluid. During the specific setting, micropores are densely arranged on the tube section located in the inner cavity of the balloon 2 on the catheter 1, so that when the fluid is passed into the catheter 1, the fluid will enter the interior of the balloon 2 through the above micropores. cavity, so that the balloon 2 is inflated after being filled with fluid.

[0032] The catheter assembly also ...

Abstract

The invention discloses an ultrasound balloon catheter assembly and catheter system, and a usage method. The ultrasound balloon catheter assembly includes a catheter and a balloon that can expand andis disposed on the catheter, the catheter passes through an inner cavity of the balloon in the axial direction and is used for introducing fluid into the inner cavity of the balloon, sealing is arranged between a peripheral portion of the balloon and the catheter, the catheter assembly further comprises an ultrasonic generation element that can emit ultrasonic waves, and the ultrasonic generationelement is disposed on the catheter and located in the inner cavity of the balloon. When the ultrasound balloon catheter assembly is applied to remove intravascular calcified plaque, it is only necessary to introduce the fluid to make the balloon full and then the ultrasonic generation element is started, so that the ultrasonic waves can be emitted and directly pass through the fluid and the balloon to directly act on the intravascular calcified plaque, thereby achieving the purpose of removing the intravascular calcified plaque. The transmittance is good, removal of calcified plaque is more direct, and safety is good.

Description

technical field [0001] The invention relates to an ultrasonic balloon catheter assembly, a catheter system and a use method, in particular to an ultrasonic balloon catheter assembly, a catheter system and a use method for removing calcified substances in blood vessels. Background technique [0002] Vascular calcification refers to the deposition of calcium salts in the walls of arteries and veins, that is, calcified plaques on the inner walls of arteries and veins, which seriously threaten the health of patients. [0003] In recent years, for calcium deposition in blood vessels, a catheter with a balloon is usually inserted into the blood vessel by means of minor surgery, and the balloon is inflated when the balloon reaches the calcium deposit, and the catheter placed in the balloon is used. The electrodes work to release high-voltage pulses, creating shock waves that travel through the fluid and hit the balloon wall and calcified areas to destroy calcium deposits with repea...
