Abstract

The invention provides a blood vessel shunt frame. The blood vessel shunt frame comprises a main body tube and at least one branch tube axially inserted into an inner cavity of the main body tube, wherein the main body tube comprises a tubular main body covering film; the at least one branch tube comprises a tubular branch covering film; the branch covering film is accommodated in an inner cavity of the main body covering film; a first sealing film is arranged between the far end of the main body covering film and the far end of the branch covering film so as to divide the inner cavity of the main body covering film into a main cavity opening and at least one sub-cavity opening; a near-end sub-cavity opening is formed in the near end of the branch covering film; and a leakage-proof part is arranged at least between the periphery of the near-end sub-cavity opening of the branch covering film and the inner surface of the main body covering film. The invention further provides a blood vessel stent provided with the blood vessel shunt frame.

Description

technical field [0001] The invention relates to the technical field of implantable blood vessels, in particular to a blood vessel shunt frame and a blood vessel stent provided with the blood vessel shunt frame. Background technique [0002] Aortic aneurysm refers to the local or diffuse abnormal expansion of the aortic wall, which compresses the surrounding organs and causes symptoms, and tumor-like rupture is its main risk. It often occurs in the ascending aorta, aortic arch, descending thoracic aorta, thoracoabdominal aorta, and abdominal aorta. According to the structure, aortic aneurysm can be divided into true aortic aneurysm and false aortic aneurysm. The aortic aneurysm causes an increase in the inner pressure of the blood vessel, so it is progressively enlarged. If it develops for a long time, it will eventually rupture. The larger the aneurysm, the greater the possibility of rupture. According to statistics, without surgical treatment, 90% of thoracic aortic aneur...
