  • Polymer compositions of dihydroxyacetone and uses thereof
    Patent number: 9629870
    Abstract: The present disclosure provides injectable synthetic and biodegradable polymeric biomaterials that effectively prevent seroma, a common postoperative complication following ablative and reconstructive surgeries. Provided biomaterials include physically crosslinked hydrogels that are thixotropic, display rapid chain relaxation, are easily extruded through narrow gauge needles, biodegrade into inert products, are well tolerated by soft tissues, and effectively prevent seroma in a radical breast mastectomy animal model.
    Type: Grant
    Filed: November 20, 2014
    Date of Patent: April 25, 2017
    Assignee: CORNELL UNIVERSITY
    Inventors: David Putnam, Peter Zaweneh, Jason Spector
