Guo's Aortic Arch Reconstruction: The First in Man Study of WeFlow-Arch Modular Embedded Branch Stent Graft System

Study Overview
=================
Brief Summary
-----------------
This study is the first in man study of WeFlow-Arch Module Embedded Aorta Arch Stent Graft System

Detailed Description
-----------------
The WeFlow-Arch Moduler Embedded Aorta Arch Stent Graft System first in man study is a prospective, single center, single arm trial, which will enroll a total of 20 patients. The goal of this study is to evaluate the safety and efficacy of WeFlow-Arch Moduler Embedded Aorta Arch Stent Graft System in the treatment of patients with lesions of the aortic arch.

| --- | --- | --- |
| Rate of no major adverse events related to device or surgery | Major adverse events related to device or surgery include: stroke, respiratory failure, pericardial tamponade, dissection or aneurysm rupture, paraplegia, stent occlusion, stent bend, stent displacement, thrombosis or rupture of the approach vessel, switch to open surgery, death, etc. | 30 days after surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Technical success rate | Successful delivery of the stent graft conveyors to their predetermined positions, accurate positioning and successful deployment of the stent, safe removal of the delivery device outside the body. | immediately after the surgery | 
| Immediate surgery success rate | Successful delivery of the stent graft, no major adverse events related to devices or surgery. | immediately after the surgery | 
| The clinical success rate | Clinical success rate：12 months after the operation, there was no displacement of the stent, I and III endoleak requiring treatment, aneurysm enlargement or rupture, and branch stent occlusion. | 12 months after the surgery | 
| The incidence rate of secondary operations within 12 months after surgery | The incidence rate of secondary operations within 12 months after surgery. | 12 months after surgery | 
| Adverse event rate within 12 months after surgery | Adverse event rate within 12 months after surgery. | 12 months after surgery |
