The Exploration of Design and Consideration Factors of Aortic Stent Graft System Clinical Trial

Aortic disease is a dangerous and critical cardiovascular disease with a high mortality rate. In recent years, aortic stent grafts for endovascular treatment have become widely used, and the development of new aortic stent grafts has been a hot spot for cardiovascular medical devices. How to carry out a reasonable and scientific clinical trial is the key in the design confirmation of aortic stent graft system. The nature, location, segment, applicable population, biomechanics and other factors of aortic disease should be considered. The effectiveness and safety endpoint, trial design type should be carefully and reasonably studied.
