Stent for peripheral blood vessels

Abstract

The invention relates to the technical field of medical stents, and provides a stent for a peripheral blood vessel. The stent comprises a stent body, wherein the stent body comprises a first end and asecond end which are located at the two ends of the stent body respectively, a plurality of supporting parts are arranged between the first end and the second end, a plurality of bridge rib parts areconnected to the supporting parts, rhombus parts are connected to the bridge rib parts, and transition parts are also connected to the bridge rib parts. By adopting the technical scheme, the supportparts, the bridge rib parts, the rhombus parts and the transition parts jointly form the stent body, on one hand, the structure of the stent body achieves enough support force, on the other hand, theuse quantity of manufacturing materials of the stent body is reduced, and in other words, when the stent body achieves enough support force, the use material coverage rate of the stent body is reduced. The stent body in the embodiment is made of nickel-titanium alloy. Besides, with the increase of the service time of the stent body, wire overlapping does not occur, and the elasticity of the stentbody is improved.

Description

technical field [0001] The invention relates to the technical field of medical stents, in particular to a stent for peripheral blood vessels. Background technique [0002] Peripheral blood vessels refer to blood vessels other than cardiovascular and cerebrovascular, which go to the thoracoabdominal and pelvic organs, as well as the trunk and extremities, including arteries, veins and capillaries. When the peripheral blood vessels are abnormal, the blood vessels in the lesion will collapse and other problems, resulting in the inability of blood to flow normally, which in turn affects the normal blood supply of related organs and causes other diseases. Therefore, clinically, stents are often used to support the collapsed blood vessels in the lesion, so that the blood can flow normally. [0003] The metal coverage on the support in the prior art is relatively large, and when the metal coverage is low, the supporting strength may be insufficient. At the same time, some stents ...

AI Technical Summary

Problems solved by technology

[0003] The metal coverage on the support in the prior art is more, and when the metal coverage is less, the support may not be strong enough

At the same time, there are still some stents that may become folded with the use of time, and the elasticity of the stent is poor
