Abstract

The present invention discloses an aortic-arch-with-branch covered stent blood vessel combined device. The aortic-arch-with-branch covered stent blood vessel combined device comprises three artificialblood vessel components: (1) a segment of a U-shaped artificial aortic blood vessel with three branches, wherein the main blood vessel at a left part of the branch is internally provided with a stent; (2) small covered stent blood vessels; and (3) a straight cylindrical stent blood vessel with a segment of a bare stent and a segment of a covered stent. The blood vessel components can isolate aortic lesions involving aortic arch and ascending aorta, at the same time rebuild branch arterial blood flow, and can preserve normal blood vessel morphology to a greatest extent. The aortic-arch-with-branch covered stent blood vessel combined device is suitable for various common branch-shaped blood vessels and wide in application ranges, avoids custom stents, can be subjected to mass production, effectively reduces surgical trauma, and is easy in surgery operations.

Description

technical field [0001] The invention relates to the field of implantable blood vessels, and relates to a covered stent assembly with three branches in the aortic arch. Background technique [0002] Thoracic aortic aneurysm and aortic dissection are serious lesions that seriously threaten the lives of the general public. Without active treatment, the natural disability rate and mortality rate are high. In recent years, with the increase in the incidence of hypertension, hyperlipidemia, hyperglycemia, and trauma, the incidence of thoracic aortic aneurysm and aortic dissection has increased significantly. At present, the use of aortic endovascular stent repair has good curative effect, less trauma and easy operation. However, aortic arch aneurysms and aortic dissection involving the innominate artery, left common carotid artery, and left subclavian artery ostium have always been difficult points in this treatment technique. In order to ensure the firm fixation of the stent in...
