  • Self-aggregating protein compositions and use as sealants
    Patent number: 8231930
    Abstract: An implantable member for use in the body is provided herein. This implantable member includes a porous biocompatible substrate; the substrate having at least one surface sealed fluid-tight with self-aggregating protein particles of substantially the same diameter range. The self-aggregated protein particles are formed from a deposited aqueous slurry of the protein particles.
    Type: Grant
    Filed: August 4, 2009
    Date of Patent: July 31, 2012
    Assignee: Maquet Cardiovascular, LLC
    Inventors: Dan Castro, Al Kuehn, Moon Hae Sunwoo

  • Self-aggregating protein compositions and use as sealants
    Patent number: 7241309
    Abstract: There is described a bio-compatible aqueous slurry for forming a fluid-tight barrier on a surface of a porous implantable article. This aqueous slurry includes a self-aggregating protein comminutate having a substantially uniform particle size, a bio-compatible plasticizer and water. This aqueous slurry is further characterized by having a viscosity of about 8,000 centipoise to about 60,000 centipoise at 25° C. and a pH sufficient to maintain the protein suspended in the slurry.
