  • Resilient foams and uses thereof
    Patent number: 10800905
    Abstract: Disclosed is a resilient foam and methods of making the foam. The resilient foam includes a derivatized polyanionic polysaccharide and has an open-cell structure. When the resilient foam is contacted with water, the foam forms a thixotropic hydrogel.
    Type: Grant
    Filed: January 4, 2019
    Date of Patent: October 13, 2020
    Assignee: SMITH & NEPHEW, INC.
    Inventors: George T. Delli-Santi, Helawe Betre

  • DIRECT DRUG DELIVERY SYSTEM BASED ON THERMALLY RESPONSIVE BIOPOLYMERS
    Publication number: 20140364371
    Abstract: A method for delivering a drug depot of a compound of interest to a selected region in a subject. The method comprises administering a composition directly to said region of interest, the composition comprising the compound of interest to be delivered (such as an antiinflammatory agent or a chemotherapeutic agent) and a polymer (such as an elastin-like peptide or ELP) that undergoes an inverse temperature phase transition, so that a sustained release of the compound of interest at the selected region is provided. Compositions useful for carrying out the invention are also described.
