  • Swellable fiber and microfiber forming polyether-esters and applications thereof
    Patent number: 9446165
    Abstract: Biomedical and tissue engineering devices, such as surgical sutures and microporous scaffolds, respectively, which undergo swelling and increase in dimensions when placed in aqueous environments such as living tissues, are produced by the melt-spinning or electrostatic spinning into strong monofilament and multifilament yarns or microfibrous fabrics, respectively. Such devices are formed from especially high molecular weight crystalline polyether-esters having a minimum inherent viscosity of 0.8 dL/g and heat of fusion of at least 5 J/g, wherein the polyether-esters are made by grafting to a polyester component a polyether glycol component having a minimum molecular weight of about 11 kDa with at least one cyclic monomer.
    Type: Grant
    Filed: July 21, 2014
    Date of Patent: September 20, 2016
    Assignee: Poly-Med, Inc.
    Inventors: Shalaby W. Shalaby, James M. Lindsey, Scott Taylor, David E. Linden, David R. Ingram
