Stent artificial blood vessel

Abstract

The invention provides a stent artificial blood vessel. The stent artificial blood vessel comprises an inflow section, a fixed side bifurcated outflow section and a movable side bifurcated outflow section; the inflow section comprises a first artificial blood vessel body and a first stent, and the first artificial blood vessel body is provided with a first outlet and a second outlet; the fixed side bifurcated outflow section is connected to the first outlet and comprises a second artificial blood vessel body and a second stent; and the movable side bifurcated outflow section is connected to the second outlet and comprises a third artificial blood vessel body and an annular stent, and the annular stent is arranged on the third artificial blood vessel body, so that at least part of the movable side bifurcated outflow section is adjustably folded in the first artificial blood vessel body. By means of the design, through the design that the movable side bifurcated outflow section is adjustably folded, the length of the outflow section can be adjusted, so that the use requirements of application environments in artery cavities such as abdominal aorta and bilateral iliac arteries are met, the physiological length of the abdominal aorta is kept, and the endoleak risk caused by sleeve connection is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent artificial blood vessel. Background technique [0002] At present, in the treatment of arterial diseases, especially for arterial diseases such as aneurysm and arterial dissection, intravascular intervention is usually used for treatment. Among them, the intervention method usually includes sending a stent artificial blood vessel into the arterial lesion in the arterial lumen, so as to realize the isolation of the arterial lesion by the artificial blood vessel and eliminate the non-physiological arterial blood flow caused by the lesion. Among them, for abdominal aortic aneurysms involving bilateral iliac arteries, bifurcated stent artificial vessels can be used for endovascular treatment. The existing bifurcated stent artificial blood vessels can be divided into two categories: combined type and integral type. The main feature of the combined bifurcated stent ar...

AI Technical Summary

Problems solved by technology

The main feature of the combined bifurcated stent artificial blood vessel is that the side branch stent and the main stent are sleeved in the abdominal aorta. horizontal while risking internal leakage due to sockets

The main feature of the integral bifurcated stent artificial blood vessel is that the bilateral branch stent and the main stent are connected as a whole, which conforms to the physiology in structure, but the disadvantage is that the operation is complicated
