  • Soft tissue mimetics and thermoplastic elastomer hydrogels
    Patent number: 10532130
    Abstract: Provided herein is a soft tissue mimetic formed from a block copolymer hydrogel and methods of making such. The hydrogel comprises a glass formed from a dry blend of polystyrene-poly(ethylene oxide) diblock copolymer (SO) and polystyrene-poly(ethylene oxide)-polystyrene triblock copolymer (SOS) in a molar ratio from between 95:5 and 1:99 SO/SOS and a liquid medium at a concentration between about 32:1 and about 2:1 liquid medium/SO-SOS by weight. The soft tissue mimetic has a fatigue resistance to at least 500,000 compression cycles.
    Type: Grant
    Filed: December 5, 2016
    Date of Patent: January 14, 2020
    Assignee: Colorado State University Research Foundation
    Inventors: Travis S. Bailey, Kristine Fischenich, Jackson T. Lewis, Tammy Haut Donahue, Chen Guo
