Flexible electrospun fiber rods and methods of manufacture

Abstract

The instant disclosure is directed to flexible electrospun fiber rods and methods of manufacturing such rods. A scaffold may comprise a flexible rod having a spiral cross-section, the flexible rod comprising electrospun polymer fibers. The electrospun polymer fibers may be substantially aligned or randomly oriented with respect to one another. The flexible rod may further comprise substantially uniformly distributed pores. The flexible rod may have a length and a diameter of a native mammalian tendon or ligament. A method of manufacturing such a scaffold may comprise forming a layer of polymer fibers on a mandrel by electrospinning, rolling the layer from a first end of the mandrel to a second end of the mandrel to form a toroid at the second end of the mandrel, and cutting the toroid off the mandrel to form a flexible rod having a spiral cross-section.
