Abstract:
Acoustophoretic devices are disclosed. The devices include a flow chamber, an ultrasonic transducer, a reflector, an inlet, a filtrate outlet, a concentrate outlet, and optionally a lipid collection trap. The ultrasonic transducer and reflector create a multi-dimensional acoustic standing wave in the flow chamber that traps and separates red blood cells and/or lipids from blood. Concentrated red blood cells can be recovered via the concentrate outlet, the lipids can be recovered via the lipid collection trap, and the remaining blood can be recovered via the filtrate outlet. Methods for separating blood components (e.g., red blood cells, lipids, platelets, white blood cells) from blood are also disclosed. The red blood cells can undergo washing with a solvent to remove undesired admixtures. Cryoprotectants can be added or removed from the blood.
Abstract:
Systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. A fluid is combined with at least one extraction solvent, which causes the lipids to separate from the fluid or from lipid-containing organisms. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to an acceptable concentration enabling the delipidated fluid to be administered to a patient without the patient experiencing undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid, to a different patient, or stored for later use.

Abstract:
An improved separating device for extracting cholesterol from plasma uses a spinner (45) to disperse incoming plasma laterally into an extracting solvent in the form of fine droplets to improve separation efficiency thereby making it suitable for delipidating blood plasma.

Abstract:
This invention is directed to systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. These systems contact a fluid with an extraction solvent, which causes the lipids in the fluid to separate from the fluid or causes lipids in the lipid-containing organisms to separate from the lipid-containingorganism, using at least one hollow fiber contactor. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to a level below a particular threshold enabling the fluid to be administered to a patient without the patient experiencing undesirable consequences. Once the fluid hasbeen processed, the fluid may be administered to a patient who donated the fluid, to a different patient, or be stored.
