The invention discloses a recyclable venous valve specially manufactured by a support and a method thereof, wherein the recyclable venous valve comprises a valve area, a valve body part and a valve leaf, the valve body part is positioned at the bottom end of the valve area, the valve leaf is positioned at the bottom end of the valve body part, the top end of the valve area is provided with a frame, a valve support body is arranged inside the valve area, the frame is composed of a connecting rod, a recycling hook, a short rod, a connecting ring, a long rod and a barb, and the valve support body is composed of a long rod of the valve area, a valve framework and a valve middle shaft section. Has the advantages that: the venous stent solves two key problems of instability of an inflow channel of the existing venous stent and insufficient support range of a pure venous valve type stent, and meets three requirements of radial support force, flexibility and vein reconstruction for stabilizing blood flow of the inflow channel; and the system is matched with the existing venous stent system, and meets the requirements of the iliac-femoral vein stenosis occlusion lesion patients under various anatomical and pathological conditions. |
