  • Patent number: 11187710
    Abstract: In some embodiments, the invention provides an in vitro method for identifying a patient as likely as likely to require a transfusion of at least six units of blood in six hours or less. The method comprise, consists essentially of, or consists of (a) analyzing a sample of blood from a patient with a viscoelastic analysis assay to obtain a coagulation characteristic value that is independent of time of the patient; and (b) comparing the coagulation characteristic value of the patient to a coagulation characteristic value that is independent of time of a control, wherein the coagulation characteristic value of the patient that is lower than the coagulation characteristic value of the control identifies the patient as likely to require a transfusion of at least six units of blood in six hours or less.

  • Patent number: 11169142
    Abstract: In some embodiments, the invention provides a method for identifying a patient suffering from or suspected of suffering in from a disease associated with the cardiovascular system that is having a subnormal response to the treatment for the disease comprising: subjecting a blood sample from a patient being treated for a disease to a viscoelastic analysis in the presence of a known amount of a thrombolytic agent, to obtain a coagulation characteristic value of the patient; and comparing the coagulation characteristic value of the patient to a coagulation characteristic value of a healthy individual, wherein a difference in the coagulation characteristic value of the patient as compared to the coagulation characteristic value of the healthy individual identifies the patient as a patient having a subnormal response to treatment.

  • Patent number: 11137409
    Abstract: In some embodiments, the invention provides methods for detecting an aberrant fibrinolysis condition in a patient. The method includes subjecting a blood sample from the patient to a viscoelastic analysis in the presence of a known amount of a thrombolytic agent, to obtain a coagulation characteristic value of the patient; and comparing the coagulation characteristic value of the patient to a coagulation characteristic value of a healthy individual, the coagulation characteristic value of the healthy individual obtained by subjecting a blood sample from a healthy individual to the viscoelastic analysis in the presence of the known amount of the thrombolytic agent, wherein a difference in the coagulation characteristic value of the patient as compared to the coagulation characteristic value of the healthy individual identifies the patent as having aberrant fibrinolysis.

  • Publication number: 20200129448
    Abstract: The current disclosure provides compositions and methods for wound closure. The disclosure provides an device comprising: a) a material with a surface comprising a modified fibrinogen or a modified fibrin, wherein the modified fibrinogen or modified fibrin is more resistant to fibrinolysis than an unmodified fibrinogen or an unmodified fibrin, respectively; and b) one or more dispersible fibrinolysis inhibitors in contact with the surface comprising a plasmin inhibitor; and c) optionally, a thrombin agent or platelets.

  • Patent number: 9354243
    Abstract: In some embodiments, the invention provides methods for detecting fibrinolysis or hyperfibrinolysis in a blood sample from a patient. The method includes subjecting a first portion of a blood sample comprising reduced platelet function to viscoelastic analysis in the absence of an inhibitor of fibrinolysis to obtain a coagulation characteristic of the first portion at a time point; and subjecting a second portion of the blood sample comprising reduced platelet function to viscoelastic analysis in the presence of an inhibitor of fibrinolysis to obtain a coagulation characteristic of the second portion at the time point; wherein a difference between the coagulation characteristic of the first portion and the coagulation characteristic of the second portion indicates fibrinolysis or hyperfibrinolysis in the blood sample.
