Balloon catheter with balloons with two asymmetric ends

Abstract

The invention discloses a balloon catheter with balloons with two asymmetric ends. The balloon catheter comprises a fixed catheter, wherein one end of the fixed catheter is fixedly connected with a catheter end; a clamping groove is formed in one end of the catheter end; a puncture needle is clamped in the clamping groove; one side of the outer surface of the fixed catheter is fixedly connected with first balloons and the other side of the outer surface of the fixed catheter is fixedly connected with first drug layers; a movable catheter sleeves the outer surface of the fixed catheter; and oneside of the outer surface of the movable catheter is fixedly connected with second balloons. According to the balloon catheter with the balloons with two asymmetric ends, through the arrangement of the clamping groove and the puncture needle, the target that the puncture needle can be properly disposed after use to reduce the risk is achieved; and through the arrangement of a first ventilation pipe, a second ventilation pipe, a third ventilation pipe and a fourth ventilation pipe, the target that the size of each balloon can be conveniently adjusted to reduce the pain of a patient is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon catheter with asymmetric balloons at both ends. Background technique [0002] Balloon catheter, also known as balloon catheter or balloon catheter, is a soft catheter with an inflatable balloon on the top. It is often used to open narrow areas or create passages in blood vessels during cardiac catheterization. When in use, the uninflated balloon is first placed in place, and then inflated according to different surgical purposes. After an outlet or passage is created in the lumen, the balloon is deflated and the catheter is removed. [0003] In the existing balloon catheters, the balloon is generally expanded synchronously, and the most suitable adjustment cannot be made according to the condition inside the blood vessel. The puncture needle is generally fixed and cannot be removed after use, which is prone to danger and cannot be used for multiple patients. Po...

Problems solved by technology

[0003] In the existing balloon catheters, the balloon is generally expanded synchronously, and the most suitable adjustment cannot be made according to the condition inside the blood vessel. The puncture needle is generally fixed and cannot be removed after use, which is prone to danger and cannot be used for multiple patients. Points to be treated at the same time, increase the treatment time, and prolong the disadvantages of the patient's suffering
