Abstract
The present invention provides a bioactive, small-diameter (typically less than 6 mm in internal diameter) vascular graft prosthesis, and is a textile conduit preferably manufactured using a novel electrospinning perfusion methodology. One preferred embodiment is a nanofibrous biocomposite textile conduit which comprises a prepared liquid admixture of polyester (Dacron), a biodurable implantable synthetic polymer, and Type IV collagen, an extracellular matrix protein. This prepared admixture and blending of diverse fibrous matter is utilized in a novel electrospinning perfusion process to form a small-diameter (less than 6 mm) fabricated textile conduit, a discrete article of manufacture, which then serves as an antecedent tangible workpiece for a subsequently-made prosthetic vascular graft construct.
