A system for intra-operative blood salvage autotransfusion is provided. The system comprises at least one inlet configured to receive whole blood of a patient; at least one curvilinear microchannel in fluid flow connection with the at least one inlet, the at least one curvilinear microchannel being adapted to isolate circulating tumor cells in the whole blood, based on cell size, along at least one portion of a cross-section of the at least one curvilinear microchannel; and at least two outlets in fluid flow connection with the at least one curvilinear microchannel, at least one outlet of the at least two outlets being configured to flow the circulating tumor cells isolated from the whole blood, and at least one other outlet of the at least two outlets being configured to flow at least a portion of a remainder of the whole blood, cleansed of the isolated circulating tumor cells, for return to the patient.
System for washing red blood cells to reduce hemolysis
A system for washing red blood cells, comprising a separator configured to separate a quantity of blood into concentrated red blood cells having a hematocrit of at least 60% and a volume of 150-250 mL, and a supernatant component. The system comprises a flow controller configured to remove the supernatant component to provide an initial red blood cell concentrate; combine 50-500 mL of an additive solution with the red blood cell concentrate to provide an intermediate red blood cell product intended for storage for 42 days or less, wherein the intermediate red blood cell product at the end of storage has an osmolarity value between 202-479 mOsm/L; and wash the intermediate red blood cell product comprising the osmolarity value between 202-479 mOsm/L with a washing solution having an osmolarity value higher than that of the intermediate red blood cell product comprising the osmolarity value between 202-479 mOsm/L.
System and method for the re-anticoagulation of platelet rich plasma
A method for the re-anticoagulation of platelet rich plasma in a blood apheresis system includes priming the blood apheresis system with anticoagulant, such that a volume of anticoagulant is transferred to a PRP container. The method may then transfer the anticoagulant within the PRP container to a red blood cell container, and collect a volume of platelet rich plasma within the PRP container. The platelet rich plasma may be collected in a plurality of cycles. Between collection cycles, the method may transfer a portion of the volume of anticoagulant from the red blood cell container to the PRP container.
Equipment and procedure for culturing, separating, and genetically modifying donor cells for reinfusion into a patient
The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.
Biological fluid filters having flexible walls and methods for making such filters
Flexible housing filters for filtration of fluids and methods of making such filters are disclosed. The filters may include one or more peripheral seals in the flexible housing.
SEQUENTIAL PROCESSING OF BIOLOGICAL FLUIDS
A process for the sequential processing of opaque and transparent biological fluids such as whole blood, apheresis blood, bone marrow blood, umbilical cord blood, buffy coat or cultured cells by processing steps in a hollow cylindrical centrifugal processing chamber (300) which is part of a disposable set. At least three different procedures selected from washing, incubation, transduction, separation, density gradient separation, dilution and volume adjustment are each carried out once or repeated a number of times according to a given processing profile in the processing chamber. Each procedure involves an input into the processing chamber, an operation in the processing chamber and an output from the processing chamber by displacement of a piston (310). The at least three different procedures are sequentially chained one after the other to constitute an overall sequential operation in the processing chamber and its disposable set. A first application is incubation for binding magnetic beads with human blood cells or stem cells. A second application is transduction by which foreign genetic material is inserted into human blood cells or stem cells by a virus. A third application is reconditioning biological fluids to achieve reproducible concentration and volumes of blood cells or stem cells.
SYSTEM AND KIT FOR THE COLLECTION AND PROCESSING OF AMNIOTIC FLUID AND PLACENTAL ASPIRATE
Disclosed is a system for the collection, processing and reuse of amniotic fluid and placental aspirate at a C-section site. The system includes a canister positioned along the vacuum line through which the amniotic fluid and placental aspirate is suctioned. The canister has a coil whereby the heavier cellular components, including stem cells, platelets and growth factors, are separated coincident with the surgical procedure. The canister has a port whereby the heavier cellular material can be removed from the canister. The heavier cellular material can be then applied to the wound site of the cesarean section patient. The system disclosed allows for the processing of the amniotic fluid and placental aspirate to take place in the same room as the surgical procedure. A kit and method are also provided.
Disposable fluid circuits and methods for cell washing with on-line dilution of cell feed
Systems and methods for the washing and processsing of biological fluid/biological cells are disclosed. The systems and methods prevent inadvertent target cell loss by monitoring pressure and providing for the dilution of the cell feed.
Smart Bag Used in Sensing Physiological and/or Physical Parameters of Bags Containing Biological Substance
The present technology discloses a cost-effective, single use bag or container for storing biological substances that incorporates on its inner wall an electronic device that is configured to measure physiological and/or physical parameters of the enclosed biological substances, such as source history, identification, demographics, time stamping, temperature, pH, conductivity, glucose, O.sub.2, CO.sub.2 levels etc. The electronic device of the disclosed bag comprises a sensor configured to measure physiological and/or physical parameters of the biological substances enclosed within the bag, and a radio-frequency (RF) device communicably coupled to the sensor and configured to: (a) acquire from the sensor data associated with the measured parameters, (b) store the acquired sensor data in nonvolatile memory, and (c) communicate the stored data wirelessly to a RF reader.
SYSTEM AND METHOD FOR IMPROVED FLUID FLOW CONTROL WITHIN A FLUID CIRCUIT CASSETTE
A fluid processing system for controlling fluid flow comprises a cassette having a defined passageway on a first side. The first side includes flexible sheeting disposed over the passageway. The system comprises a durable processing device configured to engage the first side of the cassette, the durable processing device comprising a valve actuator configured to engage the flexible sheeting at a valve location along the passageway. The system comprises a first pump configured to draw fluid away from the valve location along the passageway. The first pump is disposed downstream of the valve location. The system comprises a second pump configured to pump fluid towards the valve location along the defined passageway. The second pump is disposed upstream of the valve location. The first and second pumps are configured to operate in concert and configured to provide pressure to prevent collapsing of the flexible sheeting against the passageway during operation.
