  • Method for assaying coagulation in fluid samples
    Patent number: 7977106
    Abstract: This invention is a disposable cartridge for use at the patient side to perform traditional coagulation assays on fresh whole blood or blood derivative samples. The cartridge, in use with an electronic analyzer allows a fluid sample to be metered and quantitatively mixed with reagents which activate the coagulation cascade. An artificial substrate for thrombin, the enzyme whose action results in clot formation is also provided. Clot formation is subsequently detected using a microfabricated sensor also housed within the cartridge which detects electrochemically the product of the thrombin reaction upon the synthetic substrate.
    Type: Grant
    Filed: May 21, 2010
    Date of Patent: July 12, 2011
    Assignee: Abbott Point of Care Inc.
    Inventors: Cindra A. Widrig Opalsky, David Opalsky, Andrzej Maczuszenko, Imants R. Lauks, Rhonda J. Cheadle
