Problems solved by technology

Although all covered stents avoid the plaque and thrombus shedding caused by bare metal stents, they are easy to cover the main branches of the lesion, resulting in the interruption of the blood supply of the main branches around it, which will cause severe ischemic complications in distal tissues and organs.

Embodiment 1

[0025] Such as Figure 1 to Figure 4 As shown, the peripheral vascular stent in this embodiment includes a tapered network tube 1 and a coating 2, and the tapered network tube 1 is partially provided with a coating 2; forming a structure in which part is a bare stent and part is a coating. The covering film 2 is coated on the outside of the conical network tube 1; the peripheral vascular stent is a hollow conical tube; the small end of the conical network tube 1 is provided with a bare part 11 not covered with a film. A bare part 11 not coated with a film may be provided at the large end of the tapered network pipe 1; the bare part 11 may be ring-shaped, fan-shaped or other shapes; the bare part 11 extends to the end. The covered part can better isolate the plaque or thrombus in the diseased blood vessel, and the exposed part 11 can ensure the blood supply of the normal branch blood vessels around the diseased part. Set a developing mark on the film for identification, distin...

Abstract

The invention discloses a peripheral vascular stent. The peripheral vascular stent comprises a bare stent part and a membrane-coated stent part; and the bracket is integrally conical, thick at one endand thin at the other end. The membrane-coated part can be arranged at a thick section or a small section or can be a fan-shaped membrane. The peripheral vascular stent disclosed by the invention isset as a hollow conical tube in appearance; the hollow conical tube is matched with the diameter and shape of the blood vessel of each part of the peripheral blood vessel; and thus the peripheral vascular stent is convenient to place. According to the lesion position, an exposed part is arranged at the thick end or the thin end, so that the membrane-coated part can better isolate plaques or thrombus at the lesion blood vessel position, and meanwhile, blood supply of normal branch blood vessels around the lesion can be guaranteed as well.

Description

technical field [0001] The invention relates to a blood vessel support, in particular to a peripheral blood vessel support for treating peripheral blood vessels. Background technique [0002] Peripheral blood vessels mainly include all blood vessels except intracranial vessels and the coronary arteries of the heart, as well as the aorta and vena cava. Thrombosis and plaque on the peripheral blood vessel wall are the main causes of cerebrovascular disease or peripheral vascular disease. Peripheral vascular stents are used to support the blood vessels at the diseased part, so that the blood vessels will not elastically retract, and at the same time, it can also fix the plaque or thrombus in the blood vessel, so as to prevent the plaque or thrombus from accidentally falling off and causing vascular embolism in the target organ and other diseases. [0003] Due to the large gap of the traditional bare metal stent, it is easy to cause the plaque on the blood vessel wall or the th...
