  • Method and Apparatus for Assaying Blood Clotting
    Publication number: 20090104637
    Abstract: This invention provides an apparatus for assaying clotting activity. The apparatus includes an inlet for a blood fluid and two or more patches of material in the vessel. The material is capable of initiating a clotting pathway in a blood fluid. This invention also provides an apparatus for measuring clot propagation, which includes a region with material capable of initiating a clotting pathway, and a region where the clot propagation is monitored. Also provided are methods for assaying clotting activity, assaying the integrity of a blood clotting pathway, assaying the effect of a substance on the integrity of a blood clotting pathway, monitoring clot propagation, and preventing clot propagation from one vessel to another.
