Patent ID: 8556794

Claim:
A centrifuge device comprising a centrifuge and a scaffold material, said centrifuge being arranged for selectively concentrating and collecting constituents of a biologic liquid mixture and applying a portion of said constituents to said scaffold material, said constituents having differing specific gravities and being stratifiable in a centrifugal field produced by said centrifuge, said centrifuge comprising a chamber arranged to contain the biologic liquid mixture and having a central longitudinal axis about which said chamber is arranged to be rotated to produce said centrifugal field, a first port in fluid communication with said chamber and located a first radial distance from said central longitudinal axis, a second port in fluid communication with said chamber, a motor to rotate said chamber about said central longitudinal axis to produce said centrifugal field, whereupon said constituents of said biologic liquid mixture in said chamber stratify into at least two concentric stratified constituent layers as a function of the differing specific gravities of said constituents, said first port being selectively openable to enable at least a portion of at least one of said at least two concentric stratified constituent layers to be discharged from said chamber through said first port thereby leaving a residual of said biologic liquid mixture in said chamber, said second port being selectively openable to enable at least a portion of said residual of said biologic liquid mixture in said chamber after the opening of said first port to be discharged out of said chamber through said second port, said scaffold material being located in said centrifuge and arranged to be encountered by either at least a portion of one of said at least two concentric stratified constituent layers discharged from said chamber through said first port or at least a portion of said residual of said biologic liquid discharged out of said chamber through said second port.
