Branch Artery Reconstruction Assist Device and S-C Branch-First Aortic Reconstruction System

Abstract

The present disclosure provides a branch artery reconstruction assist device and an S-C branch-first aortic reconstruction system. The branch artery reconstruction assist device comprises a first stent body; the first stent body comprises a bare stent segment, and a proximal-side stent graft segment and a distal-side stent graft segment connected to two ends of the bare stent segment; wherein each of the proximal-side stent graft segment and the distal-side stent graft segment is provided with an occlusion membrane and at least one first stent graft channel; the occlusion membrane comprises a first opening, and the first opening is correspondingly connected to a first end of the first stent graft channel, and a second end of the first stent graft channel is connected to a corresponding branch artery stent graft to form a branch channel so as to pass through the bare stent. According to the present disclosure, the second stent body and the first stent body achieve sealing cooperation to isolate lesions, thereby ensuring that endoleak does not occur in the stents and ensuring the patency of various arteries, and normal supply of cerebral blood flow and/or organ blood flow during surgery, thereby avoiding vascular exclusion, and further reducing complications caused by ischemia.
