AI Technical Summary

Technical Problem

Existing technologies involve interruption of blood flow during balloon dilation, cumbersome procedures, and high risks associated with multiple instrument operations, resulting in low surgical efficiency and poor safety.

Method used

Design a hollow-structured integrated balloon and protective umbrella device. The balloon has a through hollow cavity, and the protective umbrella and balloon are integrated. The protective umbrella is synchronously delivered and positioned through a push tube, the support frame ensures the deployment of the protective umbrella, and the support rod and shape control components optimize the expansion and contraction.

Benefits of technology

Maintaining smooth blood flow reduces the risk of thrombosis, decreases surgical steps, shortens surgical time, reduces operational difficulty and the risk of vascular damage, and improves treatment safety and efficiency.

Abstract

This invention provides a hollow balloon and protective umbrella integrated device, belonging to the field of medical device technology. The device includes a delivery tube, a cylindrical balloon, and a protective umbrella. The cylindrical balloon is located at the distal end of the delivery tube and has a coaxially arranged hollow cavity at both ends for blood flow. The sidewall of the cylindrical balloon has a receiving chamber for holding the filling medium. The protective umbrella is integrated at a predetermined distance from the distal end of the cylindrical balloon to intercept emboli that may fall during balloon support. During operation, the cylindrical balloon and protective umbrella are delivered synchronously with the delivery tube to reduce operational steps. This invention primarily addresses the technical problems in existing technologies, such as interrupted blood flow during balloon expansion, cumbersome operational steps leading to low surgical efficiency, and high risks associated with multiple instrument operations.
