Abstract
The invention discloses a bifurcated stent with a membrane for involving a superficial femoral artery opening lesion, and relates to the technical field of medical instruments. The bifurcated stent with the membrane for involving the superficial femoral artery opening lesion comprises a main stent and a side stent; the main stent and the side stent are both of a barrel-shaped structure; one end ofthe side stent is connected with the main stent, and an included angle is formed between the side stent and the main stent, so that an inner cavity of the main stent is communicated with an inner cavity of the side stent; the length of the side stent is 2 cm, and the length of the main stent is selected according to the length of the femoral superficial artery lesion. According to the bifurcatedstent for involving the opening lesion of the superficial femoral artery, the main stent is arranged in the common femoral artery and the superficial femoral artery, and the side stent is implanted into the deep femoral artery, so that acute occlusion of the deep femoral artery caused by implantation of the stent into the opening lesion of the superficial femoral artery is prevented.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a bifurcation-grained stent for lesions involving the ostium of the superficial femoral artery. Background technique [0002] Arteriosclerotic occlusive disease of the lower extremities is a chronic disease in which atherosclerosis involves the arteries of the lower extremities, leading to arterial stenosis or occlusion, resulting in limb ischemia symptoms. It is the manifestation of systemic arteriosclerotic diseases in the lower extremities. The rate can reach 0.6% to 9.2%, which has become a common disease in vascular surgery. Isolated common femoral artery stenosis or occlusion is uncommon and often accompanied by other vessels, especially the superficial femoral artery. Lesions involving the ostium of the superficial femoral artery are difficult to treat. Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon ...
