Multi-objective design optimization of stent-grafts for the aortic arch
Materials & Design, 2023 Complications of thoracic endovascular aortic repair are closely related to the mechanical properties of implanted stent-grafts. Compared with straight vessels, the complex morphology of aortic arch imposes strict requirements on stent-graft properties ...
