Abstract:
Provided are devices, systems and methods for evaluation of hemostasis. In some embodiments, an apparatus is disclosed comprising a housing; a plurality of test chambers located in the housing, the plurality of test chambers including chambers configured for measurements via a system that interrogates one or more viscoelastic properties of test samples in the test chambers, wherein the one or more viscoelastic properties is used to characterize dynamics of coagulation and/or fibrinolysis.

Claim (Index 93):
A device comprising:\n a housing; a plurality of test chambers, wherein the plurality of test chambers includes at least a first test chamber and a second test chamber that are each at least partially defined by the housing, wherein the first test chamber and the second test chamber are each designed to receive a test sample of blood and a reagent or combination of reagents, wherein a first reagent or combination of reagents in the first test chamber is different than a second reagent or combination of reagents in the second test chamber; and a fluid pathway comprising a plurality of channels, each defined at least in part by the housing, wherein the fluid pathway includes an inlet, defined at least in part by the housing, through which the test sample is introduced into the device, wherein at least one channel of the plurality of channels is in communication with the inlet and with the first test chamber and the second test chamber to deliver a portion of the test sample to each of the first test chamber and the second test chamber, and wherein the fluid pathway includes an element having a surface defined at least in part by the housing, wherein the element is in communication with a channel of the fluid pathway and from which a pressure gradient when applied from a source external to the device draws the test sample through the fluid pathway and into at least one of the test chambers, wherein the at least one channel of the fluid pathway includes an inlet channel, a first channel, and a second channel, wherein the inlet channel is in communication with the inlet, and wherein the first channel is in communication with the inlet channel and at least with the first test chamber, and wherein the second channel is in communication with the inlet channel and at least with the second test chamber; wherein the housing includes a thermally conductive wall configured to allow the test sample to be heated, the thermally conductive wall having an outer surface area and an inner surface area; wherein the fluid pathway includes a portion at least partially defined by the inner surface area of the thermally conductive wall and the outer surface area of the thermally conductive wall is shaped to be held in at least partially conforming contact with or in close proximity to a heater to allow adjustment of a temperature of the test sample flowing through the portion at least partially defined by the inner surface area of the thermally conductive wall; wherein the first reagent or combination of reagents includes reptilase; and wherein the second reagent or combination of reagents includes one or both of adenosine diphosphate and arachidonic acid.
