Bio-inspired Metamaterial Structure Small-Diameter Vascular Grafts for Emulation of Native Arterial Mechanics

Key Points

• The aim is to develop small-diameter vascular grafts that better mimic the mechanical properties of native arteries.
• Designed bio-inspired metamaterial structures for vascular grafts.
• Analyzed mechanical strength and compliance compared to traditional grafts.
• Evaluated thrombosis rates post-transplantation.
• The new grafts exhibited significantly improved mechanical strength and compliance.
• Thrombosis incidence was notably lower in grafts using the metamaterial design.
• Transplantation outcomes showed enhanced performance compared to traditional vessels.
