Hollow balloon catheter not blocking blood/air flow

Abstract

The invention provides a balloon catheter not blocking a blood / air flow, which comprises a hollow balloon and a catheter and is characterized in that a through hole area is formed on the balloon of the balloon catheter, one or more through holes are formed in the through hole area, and therefore the hollow balloon catheter not blocking the blood / air flow is formed; the inner part of a balloon wall is in a hollow structure, and can be filled with gas or liquid; the catheter can be arranged on one side or in the center of a balloon main body and is provided with a liquid injection chamber; and the liquid injection chamber is communicated with the inner part of the balloon wall. When the hollow balloon main body expands, the balloon catheter can play a role in dilating blood vessels, while the hollow part can ensure the smooth blood / air flow, and the ischemia or necrosis of the distal blood vessels or tissues are not caused. In addition, the balloon catheter can be placed in the blood vessels and a narrow place for a longer time, and has functions of a temporary blood stent.

Description

technical field [0001] The invention relates to an interventional medical device, in particular to a medical hollow / hollow balloon catheter that is applied to systemic arteries or venous vessels without blocking blood / air flow. Background technique [0002] With the development of interventional radiology technology, the application of balloons in interventional therapy is becoming more and more extensive. When it is placed in the stenosis of the human body cavity, the cavity can be expanded within a certain period of time, so as to facilitate the treatment. At present, balloons have been successfully used for dilation of stenotic or occlusive lesions or adjuvant therapy for intracranial aneurysms. With the wide and effective therapeutic effect of the balloon interventional therapy, the used balloon has also been continuously developed and improved, which makes it more convenient in application and achieves a better therapeutic effect. [0003] For example, Chinese patent C...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a hollow / hollow balloon catheter that does not block blood / airflow. The present invention includes a balloon as a main body, and one or more through holes through the balloon are opened in the middle of the balloon, When the balloon is inflated, it plays the role of dilating blood vessels, and the hollow part with the through hole on the balloon can ensure the smooth passage of blood / airflow, avoiding ischemia or necrosis of distal blood vessels or tissues, forming energy Through the hollow / hollow balloon of blood flow, it overcomes the shortcomings of existing balloons that block blood flow and cannot be placed for a long time
