This study aims at developing biodegradable vascular grafts by combining PVA knits and porous polyvinyl alcohol PVA hydrogels. The proposed tubular PVA composites are compared to the commercially available vascular grafts in terms of compliance that best matches the compliance of natural vessels. The warp knits and weft knits are first evaluated for their circumferential properties, while the hydrogels...
This study aims to examine the properties of the small-diameter vascular grafts that are made by incorporating polyester (PET) yarns and spandex fibers. PET and spandex fibers are warp-knitted or weft-knitted into tubular knits. These two tubular knits are combined with polyvinyl alcohol (PVA) by applying a freezing-thawing method in order to create vascular grafts. The physical properties of vascular...
