Patent number: 7651474Abstract: A method and apparatus for red blood collection and filtration is provided wherein a red blood cell collection assembly provides for leukoreduction filtration concurrent with or soon after the red blood cell collection procedure. The procedure preferably involves filtering the separated red blood cells in a high hematocrit (high-crit) state prior to addition of storage solution thereto. Preferably, a storage solution is passed through the leukoreduction filter after the RBCs have been filtered therethrough. The red blood cell collection filtration and storage assembly is preferably preconnected to a blood component separation disposable assembly, including, for example, a centrifuge vessel and a blood removal/return assembly for removing blood from a donor, passing the blood to the centrifuge vessel for separation of the blood into components for collection and providing for filtration of the separated red blood cell component, as described.Type: GrantFiled: June 3, 2004Date of Patent: January 26, 2010Assignee: CaridianBCT, Inc.Inventors: Geert Van Waeg, Bruce W. Gibbs, Marc Antoon, Laura Goodrich

Patent number: 7648639Abstract: A method for separating a volume of a composite liquid into at least a first component and a second component is performed in a centrifuge cooperating with a separation bag containing the volume of composite liquid. The separation bag is connected to at least a first component bag and a second component bag. The separation bag is spun so as to centrifuge the volume of composite liquid and cause the sedimentation of the at least first and second components. When the at least first and second components have sedimented, the first component is transferred at least one first transfer flow rate into the first component bag. When the first component has been transferred into the first component bag, the second component is transferred into the intermediate component bag at least one second transfer flow rate that is different from the at least one first transfer flow rate.Type: GrantFiled: December 14, 2007Date of Patent: January 19, 2010Assignee: CaridianBCT, IncInventors: Brian M.

Patent number: 7497944Abstract: A system and method are used in connection with processing of blood components. The processing of blood components may involve centrifugal separation and/or filtering of the blood components. In some examples, at least some blood components are centrifugally separated in a chamber and then filtered via a filter rotating along with a centrifuge rotor, wherein the filter is located closer than the chamber to an axis of rotation of the rotor. The filter may include a porous filtration medium configured to filter leukocytes, platelets, and/or red blood cells. Some examples include a pressure sensor sensing pressure of pumped blood components. The sensed pressure may be used in connection with controlling the pumping of the blood products and/or in connection with determining the location of an interface associated with the blood products. Other uses of the sensed pressure are also possible.Type: GrantFiled: March 27, 2007Date of Patent: March 3, 2009Assignee: CaridianBCT, Inc.Inventors: Niclas Högberg, Emanuel Hällgren, Peter Pihlstedt, Brian M.
