Abstract: A hemostasis analyzer, such as the Thrombelastograph® (TEG®) hemostasis analyzer is utilized to measure continuously in real time, the hemostasis process from the initial fibrin formation, through platelet-fibrin interaction and lysis to generate blood hemostasis parameters. The measured blood hemostasis parameters permit determination of heparin-induced thrombocytopenia II complex (HiT II).

Abstract: A method and device for blood hemostasis analysis is disclosed. A blood sample is displaced to reach a resonant state. The resonant frequency of the blood sample is determined before, during and after a hemostasis process. The changes in the resonant frequency of the blood sample are indicative of the hemostasis characteristics of the blood sample.

Abstract: Apparatus for measuring hemostasis includes a container for holding a sample to be tested and a bobber configured to be buoyantly suspended on the sample. A magnet is secured to the bobber. A drive assembly is coupled to the container for driving the container in an oscillating motion. A magnetic field generator is disposed adjacent the container and configured to generate a magnetic field in the vicinity of the magnet. A magnetic field strength detector is disposed adjacent the container, and the magnetic field strength detector is configured to sense changes in the magnetic field as a result of movement of the bobber and magnet responsive to the oscillating motion of the container and clotting of the sample.

Abstract: A sample retention apparatus for use in a device for measuring hemostasis. The device for measuring hemostasis may include a sample articulation apparatus including a guide shaft coupled for articulating motion to a drive motor, a sample carrier secured to and axially moveable along the guide shaft between a sample ready position, a sample testing position and a sample ejection position. The sample carrier therefore articulates in unison with the articulating motion of the guide shaft. A measuring apparatus may include a sensing column. The sample retention apparatus may include a sample cup defining a volume within which a sample may be disposed. The sample cup may be adapted to be operably positioned within an aperture formed within the sample carrier. The sample testing apparatus may also include a sample pin that is engageable with the sensing column. The sample pin may include a tip portion for extending into the sample cup.

Abstract: A method and apparatus for monitoring hemostasis in a connection with a recipient of an artificial surface device provide a multi-phase monitoring protocol. In a first, pre- and intra-operative phase, hemostasis of the recipient is monitored relative to preventing clot formation to achieve artificial surface patency. In a second, post operative phase hemostasis of the recipient is monitored relative to bringing about clot formation to achieve vascular recovery. In a third, stabilizing intensive care phase hemostasis of the recipient is monitored relative to balancing hemostasis toward an anti-coagulation bias. In a fourth, maintenance phase hemostasis is monitored relative to maintaining balanced hemostasis.

Abstract: A system and method for diagnosing hemostasis utilizing a communication network. A blood hemostasis analyzer tests a blood sample and provides a parameter indicative of hemostasis. The blood hemostasis analyzer is communicatively coupled via the communication network to an analysis tool. The analysis tool includes an algorithm operable on the parameter to provide a result. The diagnostic result may indicate normal hemostasis, a coagulopathy or other condition, and may provide a recommended course of treatment.

Abstract: A procedure for hemostasis and blood management, particularly for cardiovascular procedures, provides: sampling instructions, i.e., when to draw blood samples and how to pre-treat the blood samples, a decision tree to assist the interpretation of hemostasis analysis results allowing for the identification of various coagulopathies, and treatment suggestions related to the hemostasis analysis results. The analysis, interpretation and identification may be conducted by a suitably programmed computer.

Abstract: A blood coagulation analyzer, such as the Thrombelastograph® (TEG®) blood coagulation analyzer is utilized to measure continuously in real time, the clotting process from the initial fibrin formation, through platelet-fibrin interaction and lysis to generate blood coagulation parameters. The measured blood coagulation parameters permit confirmation of the attainment of therapeutic level of GPIIb/IIIa receptor blockade; individualized dosing assessment to evaluate attainment of adequate GPIIb/IIIa receptor blockade; individualized dosing assessment required to reach adequate GPIIb/IIIa receptor blockade; illustration of the rate of diminishment of platelet inhibition or inhibition recovery after treatment with platelet-inhibition drugs; evaluation of the interaction effect of a combination of thrombolytic or any other agents or conditions effecting hemostasis and platelet-inhibiting agents on patient hemostasis.

Abstract: A method and apparatus are provided for measuring hemostasis. The apparatus includes a torque sensing column having a torque sensing element and a drive ring disposed around a body of the column and in registration with the column so as to allow rotation of the drive ring around a longitudinal axis of the column. The apparatus further includes a first guide shaft rigidly secured to the drive ring, the guide shaft extending parallel to the longitudinal axis of the column and a cup holder movably attached to the guide shaft, allowing the cup holder to move parallel to the longitudinal axis of the column. The apparatus also includes a sample cup adapted to engage the cup holder on a outer surface and the torque sensing element of the torque sensing column on an inner surface.

Abstract: An instrument for measuring the coagulation characteristics of whole blood samples is provided with disposable parts for contacting the blood. The pin has a blood-compatible plastic sleeve surrounding a metal stem which weights the pin assembly so it sinks into the blood sample. The metal stem also engages into the pin suspension apparatus of the instrument. A blood-compatible plastic cup receives the blood sample to be tested, and is surrounded by a metal collar to transfer heat to the cup for the time required for a test. The plastic surfaces which contact the blood sample are slightly roughened, to a matte finish, to improve adhesion so as to approximate the results obtained with stainless steel pins and cups.
