  • Patent number: 9421096
    Abstract: An expandable venous valve having a support structure that is configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame sections or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure.

  • Publication number: 20160184835
    Abstract: Fluid separation chambers are provided for rotation about an axis in a fluid processing system. The fluid separation chamber may be provided with first and second stages, with the first and second stages being positioned at different axial locations. In another embodiment, at least one of the stages may be provided with a non-uniform outer diameter about the rotational axis, which may define a generally spiral-shaped profile or a different profile for fractionating a fluid or fluid component. One or more of the stages may also have a varying outer diameter along the axis. The profile of the chamber may be provided by the chamber itself (in the case of rigid chambers) or by an associated fixture or centrifuge apparatus (in the case of flexible chambers).

  • Publication number: 20140357465
    Abstract: Systems and methods are provided for processing blood or a fluid containing blood plasma and platelets. The blood or fluid is continuously added into a fluid separation chamber, which is used to isolate platelet-rich plasma therein. At least a portion of the platelet-rich plasma is automatically transferred from the fluid separation chamber into an injection device, with the fluid separation chamber and the injection device comprising components of a disposable flow circuit, which may be a closed system. One or more injection devices may be connected to a collection container or a pump device of the disposable flow circuit.

  • Publication number: 20140350450
    Abstract: Systems and methods are provided for performing a medical procedure with respect to a subject. A data storage location of the system is pre-programmed with a plurality of subject data entries, each having subject-specific information associated with it. A user interface receives an identity input from a subject, which corresponds to the identity of the subject. A controller is associated with the database and the user interface, and is programmed to compare the identity input to the subject data entries. If the identity input corresponds to the subject-specific information of a subject data entry, the controller commands a treatment device to perform a medical procedure with respect to the subject. Otherwise, if the identity input does not correspond to the subject-specific information of any of the subject data entries, the controller generates an error signal which prevents the performance of the medical procedure with respect to the subject.

  • Patent number: 8852140
    Abstract: Systems and methods are provided for automatically adjusting the operational parameters of a blood separation procedure. A blood separation device has an inlet for passing fluid thereinto and an outlet for removing fluid therefrom. A pump system is provided for moving fluid into and out of the device. In use, blood is conveyed into the device, where platelets are separated from at least a portion of the blood. A controller determines the amount of platelets in the device. Based at least in part on the amount of platelets in the device, corrective action is taken to avoid platelet aggregation in the device. The corrective action may be conveying an elevated amount of anticoagulant into the blood and/or the device and may be initiated when the determined amount of platelets approaches, meets, or exceeds a threshold predicted likelihood of platelet aggregation.

  • Publication number: 20140291248
    Abstract: Blood treatment systems and methods are provided for combining a blood separation system and an adsorption device. The blood separation system is configured to separate a blood component from blood, while the adsorption device is configured to receive at least a portion of the separated blood component and process it. The blood separation system includes a fluid flow element and a controller. The fluid flow element is configured for flowing the separated blood component into the adsorption device. The controller controls the fluid flow element based at least in part on one or more processing parameters. The processing parameters include a maximum flow rate of the separated blood component flowed into the adsorption device, a maximum pressure of the separated blood component flowed into the adsorption device, and/or the volume of fluid in a location of the system.

  • Patent number: 8676600
    Abstract: Certain examples provide systems, methods, and apparatus to provide information regarding blood donation. Certain examples include a method for providing blood collection information to a donor. The method includes displaying a graphical representation of a donor's donation progress toward a goal for blood component collection to a donor via an executable application icon on a mobile device. The graphical representation is to provide a visual indication of the donor's donation progress toward a goal. The donor's donation progress toward the goal is based on data from a donation facility provided to the mobile device and is displayed via the graphical representation without the donor executing the application. The method includes facilitating access to additional blood donation information for the donor by executing the application via the graphical representation on the mobile device. The method includes facilitating donor action with respect to the blood donation information via the mobile device.

  • Publication number: 20140057771
    Abstract: An optical monitoring system is provided for use with a blood processing system. The system includes a light source configured to illuminate a disposable flow circuit received in a centrifuge and a light detector configured to receive an image of the disposable flow circuit. A controller combines two or more of the images received by the light detector to generate a two-dimensional output. The output is used to control the separation of blood within the disposable flow circuit. The monitoring system may also be used to verify that the disposable flow circuit is suitable for use with the centrifuge or that the disposable flow circuit is properly aligned within the centrifuge. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge.
