AI Technical Summary

Technical Problem

Existing stent devices require additional procedures, such as a second balloon catheter, during deployment, increasing surgical costs and time, and lacking a low-complexity design.

Method used

A support device is designed, comprising a radially expandable main body and an outwardly opening portion. The opening connector automatically opens radially outward when the main body expands radially, forming an opening crown, thus avoiding additional manipulation steps.

Benefits of technology

This simplified the deployment process of the stent device, reduced surgical costs and time, provided a clear post-deployment access, and enhanced fixation with the vessel wall.

Abstract

本申请提供了一种支架装置。所述支架装置包括：至少一个可径向扩张主体部分，其沿着所述支架装置的纵向轴线延伸、限定管腔；以及至少一个可向外张开部分，其连接到所述主体部分。所述可向外张开部分包括：至少一个可径向扩张环，其连接到所述主体部分；以及至少一个张开连接件，其连接到所述至少一个环、被构造成在所述主体部分径向扩张时使所述至少一个环的冠部相对于所述环的其他部分而自动径向向外张开，从而形成张开冠部。在径向扩张之后，向外张开部分可以通过减弱其坍缩能力的支撑支柱保持就位。
