AI Technical Summary

Technical Problem

Thickening of the inner wall of blood vessels leads to narrowing of the blood vessel channel, affecting blood flow. Current technology is difficult to effectively dilate blood vessels and maintain normal blood flow, and the dilation process may cause harm to patients.

Method used

Design a vascular stent graft, comprising an expandable stent and an artificial vascular graft. The expandable stent consists of an inlet section, a main body section, and an outlet section. It supports branch vessels and employs a mesh structure. The artificial vascular graft covers the mesh of the expandable stent to prevent vascular wall proliferation and maintain unobstructed blood flow.

Benefits of technology

It effectively dilates blood vessels, prevents vascular stenosis, maintains normal blood flow, reduces the adverse effects of the dilation process on patients, and prevents blood stasis.

Abstract

The application relates to the technical field of medical devices, and particularly provides a blood vessel covered stent, which comprises an expansion stent and an artificial blood vessel cover. The expansion stent is inserted into a branch blood vessel through a branch opening of a blood vessel. The expansion stent is provided with an entering part, a main body part and an outflow part from the branch opening to the deep part of the branch blood vessel. The artificial blood vessel cover is attached to the expansion stent. The blood vessel is expanded by the expansion stent, the blood vessel channel is prevented from being narrowed, the normal blood circulation in the blood vessel is maintained, the expansion stent and the inner wall of the blood vessel are separated by the artificial blood vessel cover, the inner wall of the blood vessel is prevented from proliferating into the inner cavity of the expansion stent, and the blood channel in the expansion stent is maintained unobstructed.
