Problems solved by technology

[0004] However, while the shock wave balloon catheter based on the electrohydraulic effect exhibits excellent therapeutic effects, the disadvantages of the device itself are also revealed. The main problem is the poor passability. When treating stenotic lesions, pre-expanded balloons are required. Or use the atherectomy catheter to assist the opening of stenotic lesions. The operation is very cumbersome, the operation efficiency is low, and the ability to fit the lesion is poor, and the applicable blood vessel size is limited, and the scope of use is limited.

Embodiment 1

[0043] Please refer to figure 1 , this embodiment provides a medical device, which includes a catheter body, a balloon 12 and an energy generating component. The end of the catheter body is accommodated in the balloon 12, the balloon 12 is sheathed on the end of the catheter body, and the proximal end and the distal end of the balloon 12 are respectively fixedly connected with the catheter body. The interior of the balloon 12 is used to store the conductive medium. The energy generating component includes at least one electrode pair, the electrode pair includes a first electrode 15 and a second electrode 16, one of the first electrode 15 and the second electrode 16 is a positive electrode, and the other is a negative electrode. At least one electrode pair is arranged at the end of the catheter body and inside the balloon 12 to ensure safety in use. At least one of said electrode pairs is used to receive high voltage pulses to generate shock waves. In one embodiment, the cat...

Abstract

The invention relates to a medical device which comprises a catheter body, a balloon and an energy generating component, the energy generating component comprises at least one electrode pair, the at least one electrode pair is arranged at the tail end of the catheter body and located in the balloon, the interior of the balloon is used for storing a conducting medium, and the balloon is made of a high-elasticity material; and the balloon in the contracted state is sleeved at the tail end of the catheter body in an unfolded manner. Through the configuration, the passing outer diameter of the medical device based on the liquid-electric effect can be reduced, so that the treatment of narrow lesions can be realized, and the treatment difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical device. Background technique [0002] The shock wave balloon catheter based on the electrohydraulic effect is an emerging medical device for angioplasty, which has attracted extensive attention from the medical circles at home and abroad. own damage. [0003] Prior to this, for severe calcified lesions, it often happened that conventional dilation balloons could not achieve lesion expansion. At this time, special instruments, such as rotational atherectomy catheters, cutting balloons, spinous process balloons, etc., were needed to prevent calcified areas. deal with. The shock wave balloon catheter uses the electro-hydraulic effect to directly apply the sound pressure to the hard calcified layer to destroy the calcified structure and achieve rapid destruction and expansion of the calcified lesion. At the same time, due to the selectivity of the electrohydrauli...
