Patent number: 7354415Abstract: Methods and apparatus particularly involving the separation of blood into blood components and the collection of such components are disclosed. In one aspect, an extra-corporeal method for the collection of plasma and red blood cells is provided, wherein the collection of plasma and red blood cells may occur simultaneously or subsequently utilizing the same dual stage blood processing vessel. The flow of blood to the blood processing vessel and return of uncollected blood components may be provided via a single needle, wherein blood is removed from and returned to a donor/patient during alternating blood removal and blood return submodes. Platelet separation and collection options are also described. In either case, prior to red blood cell collection, a set-up phase may be carried out to set a predetermined hematocrit and AC ratio. Replacement fluid delivery may optionally also be provided either substantially continuously during any collection phase(s) and/or in a bolus mode.Type: GrantFiled: April 20, 2004Date of Patent: April 8, 2008Assignee: Gambro BCT, Inc.Inventors: Marlene Bainbridge, Muriel Keller, Timothy M. Gordon, Michael J. McAteer, Scott D. Butzke

Patent number: 6773413Abstract: An extracorporeal blood processing method includes a set-up phase establishing certain conditions in blood being processed prior to separation of the blood into components. Also, a blood processing method contemporaneously extracts selected multiple blood components from a blood processing vessel. Blood is separated into components in the blood processing vessel in a centrifugal field. Further, an extracorporeal blood processing method establishes a packing factor in the blood processing vessel prior to collecting red blood cells.Type: GrantFiled: December 4, 2000Date of Patent: August 10, 2004Assignee: Gamero IncInventors: Muriel Keller, Marlene Bainbridge

Publication number: 20010000185Abstract: Improved extracorporeal blood processing methods and apparatus are disclosed. In one aspect of the invention, an extracorporeal method for the collection of platelets and red blood cells, and if desired plasma, is provided, wherein the collection of platelets and red blood cells may occur in differing time periods utilizing the same blood processing vessel. The flow of blood to the blood processing vessel and return of uncollected blood components may be provided via a single needle, wherein blood is removed and returned to a donor/patient during alternating blood removal and blood return submodes. Prior to red blood cell collection, a set-up phase may be carried out during which a predetermined hematocrit and AC ratio is established.Type: ApplicationFiled: December 4, 2000Publication date: April 5, 2001Inventors: Muriel Keller, Marlene Bainbridge
