20120220915SYSTEMS AND METHODS FOR SINGLE NEEDLE CONTINUOUS PLASMA PROCESSING - Certain examples describe systems and methods for increasing plasma extracted from donor blood. An example method includes receiving blood extracted from a donor connected to a blood collection machine. The example method includes filtering the blood using a filtration device to remove at least a portion of plasma included in the blood to separate the plasma removed from remaining blood. The example method includes routing the plasma removed for collection. The example method includes re-filtering the remaining blood using a or the filtration device to remove additional plasma from the remaining blood. The example method includes routing the additional plasma removed for collection.08-30-2012
20130012860METHODS AND COMPOSITIONS TO PREDICT AND DETECT ACUTE REJECTION - In some embodiments, a method to detect acute rejection in allograft from is described. In some embodiments, a method to anticipate an episode of acute rejection in allografts is also described. In some embodiments, a kit for detecting or predicting acute transplant rejection of a transplanted organ is described.01-10-2013
20130066252METHOD FOR DIAGNOSIS FOR MULTIPLE SCLEROSIS INVOLVING ANTI1-RECEPTOR ANTIBODY - The invention relates to a method for diagnosis of multiple sclerosis (MS) wherein, presence or absence of an anti-AT03-14-2013
20130131573SELECTIVE ANTI-HLA ANTIBODY REMOVAL DEVICE AND METHODS OF PRODUCTION AND USE THEREOF - An anti-MHC removal device includes a serologically active, soluble MHC moiety covalently coupled to a solid support. Methods of production include covalently coupling the serologically active, soluble MHC moiety to the solid support. Methods of use of the anti-MHC removal device include contacting a biological sample with the device so that antibodies specific for the MHC moiety are removed from the biological sample. The biological sample is then recovered.05-23-2013

20140100506Three-Line Apheresis System and Method - A blood processing system for collecting and exchanging blood components includes a venous-access device for drawing whole blood from a subject and returning blood components to the subject. The system may include three lines connecting the venous access device to a blood component separation device and an anticoagulant source. A blood draw line fluidly connects to the venous-access device to the blood component separation device. An anticoagulant line introduces anticoagulant into the drawn whole blood. A return line, fluidly connected to the venous-access device and the blood component separation device, returns uncollected blood component to the subject. Each line may have a pump that controls flow through the line. The blood component separation device separates the drawn blood into a first blood component and a second blood component, and may be configured to send the first blood component to a first blood component bag.04-10-2014
20140100507PRIMING ANTICOAGULANT LINE FOR BLOOD EXTRACTION - Methods and devices are described for reducing anticoagulant dilution of collected blood components during blood collection.04-10-2014
20150073327Tip Configurations for Multi-Lumen Catheter - Multi-lumen catheters with improved tip configurations, including a triple-lumen catheter which may be useful for apheresis. In one variation, the catheter has three lumens with distal openings angularly spaced apart and staggered axially with respect to one another. In another variation, the catheter has two lumens exiting distally and one centrally positioned lumen exiting proximally. A third variation is a catheter with a single distal opening and two proximal openings. The staggered lumen openings along the axial length of the catheter may decrease recirculation while maximizing flow rates.03-12-2015
