Remodeling of structurally reinforced (TPU+PCL/PCL)-Hep electrospun small-diameter bilayer vascular grafts interposed in rat abdominal aortas

Structurally reinforced and surface-heparinized (TPU+PCL/PCL)-Hep electrospun small-diameter bilayer vascular grafts improve the mechanical properties, completely inhibit aneurysm and promote vascular remodeling with more elastin deposition in vivo .
