Embodiment 1

[0042] see Figure 1-Figure 4 As shown, the present embodiment provides a vascular stent; Figure 1-Figure 4 The first structural schematic diagram to the fourth schematic structural schematic diagram of the vascular stent provided in this embodiment.

[0043] see Figure 1-Figure 4 As shown, the vascular stent provided in this embodiment is suitable for bifurcated diseased blood vessels, especially suitable for bifurcated blood vessels of the common femoral artery, deep femoral artery, and superficial femoral artery.

[0044] The vascular stent includes a main stent part 110 , a first sub-stent part 120 and a second sub-stent part 130 .

[0045] The first end of the first sub-support part 120 and the first end of the second sub-support part 130 communicate with the same end of the main support part 110 respectively.

[0046] The corresponding second end of the first sub-support part 120 is wedge-shaped or inclined, and / or the corresponding second end of the second sub-supp...

Abstract

The invention relates to the technical field of medical appliances, in particular to a vascular stent and a vascular coating stent. The vascular stent comprises a main stent portion, a first secondarystent portion and a second secondary stent portion; a first end of the first secondary stent portion and a first end of the second secondary stent portion separately communicate with the same end ofthe main stent portion; and the corresponding second end of the first secondary stent portion is wedge-shaped or is an inclined plane, and / or the corresponding second end of the second secondary stentportion is wedge-shaped or is an inclined plane. The vascular coating stent comprises the vascular stent; and a drug coating coats the outside of the vascular stent. The invention aims to provide thevascular stent and the vascular coating stent to solve the technical problems that in the prior art, two stents are required to be fed into a bifurcation lesion blood vessel, and surgical operationsare complicated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood vessel stent and a blood vessel coating stent. Background technique [0002] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon expansion to support the stenotic and occluded segment of the vessel, reduce elastic recoil and reshaping of the vessel, and maintain smooth blood flow in the lumen. Some internal stents can also prevent restenosis. [0003] In actual clinical practice, the stenosis of blood vessels in many patients is not limited to one place, but is located in multiple places of the blood vessels. A common form of multiple arterial narrowing is bifurcation diseased vessels. At present, two stents are sent into the main vessel and the branch vessel respectively by Crash technology; for example, the main stent sent into the main vessel and the branch stent sent into the branch vessel are in pl...
