  • Patent number: 11338057
    Abstract: Implantable scaffolds made from biopolymer fibers. Biopolymer is dissolved in acid in a closed container made of materials inert to the acid and to the collagen to form a biopolymer solution. The solution is stirred, then centrifuged to degas it. The degassed solution is put into syringes on a holder. The number of syringes equals the number of fibers in the bundle. The syringes are mounted in a rotatable holder. Essentially equal quantities of degassed solution are extruded from the syringes to produce fibers, which are gathered and fed into a formation buffer bath. The fibers are kept taught after extrusion and dehydrated in a dehydrating solution in a dehydrating bath. The fibers are wound a collector to collect the bundle. Scaffolds then are made.

  • Patent number: 11020509
    Abstract: A biopolymer fiber containing collagen. The biopolymer fiber has excellent ultimate tensile strength, modulus of elasticity, and strain at break comparable to native human tendons and ligaments. The fiber may substantially circular, ovoid, square, rectangular, ribbon-like, triangular, or irregularly shaped. The fiber exhibits an ordered, longitudinally-oriented structure, and the fiber allows infiltration of cellular growth. Implantable biopolymer scaffolds and sutures containing the fibers are provided as well as microfluidic and extrusion methods for producing the biopolymer fibers.
