Patent number: 9649579Abstract: A separator that uses centrifugation to fractionate a suspension such as blood comprises a separation container and a buoy. The buoy is carried in the separation container and has a tuned density that is configured to reach an equilibrium position in a suspension. The guide surface is carried on the buoy upper surface and is inclined to an accumulation position near a buoy perimeter. The buoy suspension fractionation system can be used in a method of isolating a fraction from a suspension, and in a method for re-suspending particulates for withdrawal.Type: GrantFiled: December 10, 2012Date of Patent: May 16, 2017Assignees: Hanuman LLC, Biomet Biologics, LLCInventors: Michael D.

Patent number: 8950586Abstract: A platelet collection device comprising a centrifugal spin-separator container with a cavity having a longitudinal inner surface. A float in the cavity has a base, a platelet collection surface above the base, an outer surface. The float density is below the density of erythrocytes and above the density of plasma. The platelet collection surface has a position on the float which places it below the level of platelets when the float is suspended in separated blood. During centrifugation, a layer of platelets or buffy coat collects closely adjacent the platelet collection surface. Movement of a float having a density greater than whole blood through the sedimenting erythrocytes releases entrapped platelets, increasing the platelet yield.Type: GrantFiled: July 1, 2013Date of Patent: February 10, 2015Assignee: Hanuman LLCInventors: Randel Dorian, Richard W. Storrs, Scott R. King

Patent number: 8133389Abstract: The PRP separator-concentrator of this invention is suitable for office use or emergency use for trauma victims. The PRP separator comprises a motorized centrifugal separation assembly, and a concentrator assembly. The centrifugal separator assembly comprises a centrifugal drum separator that includes an erythrocyte capture module and a motor having a drive axis connected to the centrifugal drum separator. The concentrator assembly comprises a water-removal module for preparing PRP concentrate. The centrifugal drum separator has an erythrocyte trap. The water removal module can be a syringe device with water absorbing beads or it can be a pump-hollow fiber cartridge assembly. The hollow fibers are membranes with pores that allow the flow of water through the fiber membrane while excluding flow of clotting factors useful for sealing and adhering tissue and growth factors helpful for healing while avoiding activation of platelets and disruption of any trace erythrocytes present in the PRP.Type: GrantFiled: July 29, 2011Date of Patent: March 13, 2012Assignees: Hanuman, LLC, Biomet Biologics, LLCInventors: Randel Dorian, Michael D.

Patent number: 8105495Abstract: A process for separating platelet rich plasma from a blood sample using a platelet rich plasma separator system is disclosed. The system includes an inner wall having a top edge and a central axis that is surrounded by a depth filter having a capacity to receive all of the erythrocytes in the blood sample, where an inner surface of the inner wall has an angle of about 0.2° from the central axis of the inner wall. The process includes spinning the inner cylinder at its central axis at a speed that separates the erythrocytes from plasma and platelets and causes the erythrocytes to collect against an inner surface of the depth filter. The cylinder is continually spun for a sufficient time to allow substantially all of the erythrocytes to flow up the inner surface and over the top edge into the depth filter, leaving platelet enriched plasma (PRP) in the inner cylinder, such that upon discontinuing the spinning, permits the platelet enriched plasma to flow to the bottom of the inner cylinder.Type: GrantFiled: January 10, 2011Date of Patent: January 31, 2012Assignees: Hanuman, LLC, Biomet Biologics, LLCInventors: Randel Dorian, Michael D.
