Abstract

The invention discloses a novel bracket type blood vessel, which comprises a trunk and a branch part, wherein the trunk comprises at least one embedded branch which extends towards the inner wall of the trunk and is communicated with the trunk; the port of the embedded branch is trumpet-shaped; and after a bracket is released, the released trunk can be prevented from damaging a branch blood vessel, and the introducing joint stability of a split module is enhanced simultaneously. The novel bracket type blood vessel further comprises at least one epitaxial branch which extends outwards.

Description

Technical field

[0001] The invention relates to the field of implantable blood vessels, in particular to an intervenable stent-type blood vessel. Background technique

[0002] Aortic aneurysm and dissection are clinically very dangerous vascular diseases, and should be treated accordingly as soon as they are discovered. At present, the minimally invasive interventional therapy technology using the principle of intracavitary isolation has been widely used. It uses a delivery system with a small diameter to deliver the compressed stent-graft with support to the position of the vascular lesion. After accurate positioning, it is released to cover the diseased blood vessel, isolate the vascular lesion and form a new blood flow channels.

[0003] The currently produced vascular stents can be divided into straight type, branch / fork type, etc. Among them, the branch / fork vascular stent includes an integrated structure and a split structure. The split structure is generally compose...
