Vascular Stents and Stent Components

Abstract

A vascular stent and a stent assembly, belonging to the field of medical devices, the vascular stent includes a first stent unit, a second stent unit, and a first connecting piece, the first stent unit and the second stent unit are connected through the first connecting piece, and the second stent The unit can be accommodated in the first bracket unit through elastic deformation of the first connecting piece. The stent assembly includes the above-mentioned vascular stent. The vascular stent can not only expand radially, but also expand axially. Even if the diseased blood vessel is long, it does not need to be implanted in multiple segments, thereby shortening the operation time, reducing the operation risk, improving the simplicity of the operation, and reducing postoperative restenosis. The incidence of disease, improve the treatment effect of the disease. The stent component can efficiently and concisely implant a vascular stent into a long diseased blood vessel without multiple segmental implantation, and has the characteristics of short operation time, low risk and good effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a vascular stent and a stent assembly. Background technique [0002] Medical stents are one of the commonly used medical devices, which can be implanted into diseased blood vessels to open the diseased blood vessels to make blood flow unobstructed. They are often used to treat vascular stenosis, repair and rebuild blood vessels. [0003] However, the existing vascular stents can only be expanded radially, but cannot be lengthened axially. When the diseased blood vessel is relatively long, it must be implanted multiple times and in sections, which will not only increase the risk of surgery, but also increase the incidence of postoperative restenosis, thereby affecting the simplicity of surgery and the therapeutic effect of the disease. Contents of the invention [0004] The object of the present invention is to provide a vascular stent, which can not only expand radially, but als...
