C12M47/02
Non-planar and non-symmetrical piezoelectric crystals and reflectors
An acoustophoretic device is disclosed. The acoustophoretic device includes an acoustic chamber, an ultrasonic transducer, and a reflector. The ultrasonic transducer includes a piezoelectric material driven by a voltage signal to create a multi-dimensional acoustic standing wave in the acoustic chamber emanating from a non-planar face of the piezoelectric material. A method for separating a second fluid or a particulate from a host fluid is also disclosed. The method includes flowing the mixture through an acoustophoretic device. A voltage signal is sent to drive the ultrasonic transducer to create the multi-dimensional acoustic standing wave in the acoustic chamber such that the second fluid or particulate is continuously trapped in the standing wave, and then agglomerates, aggregates, clumps, or coalesces together, and subsequently rises or settles out of the host fluid due to buoyancy or gravity forces, and exits the acoustic chamber.
CELL CULTURE DEVICE AND METHOD OF USING THE SAME
The present invention relates to a cell culture device comprising at least a fluidic channel having at least a cell medium inlet and a cell medium outlet, said fluidic channel comprising a lower wall extending between the cell medium inlet and the cell medium outlet, the cell culture device further comprising at least one recess configured to receive a plurality of cells, said recess being formed by the lower wall and defining a bottom surface, and at least a cell trap, said cell trap being configured to capture a cell advected in the fluidic channel and then to make the cell sediment to the bottom surface of the recess.
PARAMETERS FOR CONCENTRATION AND WASHING OF PARTICLES WITH ACOUSTICS
Multi-stage acoustophoretic devices for continuously separating a second fluid or a particulate from a host fluid are disclosed. Methods of operating the multi-stage acoustophoretic devices are also disclosed. The systems may include multiple acoustophoretic devices fluidly connected to one another in series, each acoustophoretic device comprising a flow chamber, an ultrasonic transducer capable of creating a multi-dimensional acoustic standing wave, and a reflector. The systems can further include pumps and flowmeters.
CARTRIDGES FOR CELL PROCESSING
Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.
BIOREACTOR AND METHOD FOR CULTIVATING BIOLOGICAL CELLS ON SUBSTRATE FILAMENTS
The invention relates to a bioreactor (100) which is designed for cultivating biological cells (1), comprising a container (10) configured to receive a cultivation medium (2), and a plurality of substrate filaments (20) which are arranged in the container (10) and are configured for a temporary adherent coupling of the biological cells (1) to the substrate filaments (20). The substrate filaments (20) are provided with a surface layer (21) which is switchable between an adherence state, in which the biological cells (1) can be QI coupled adherently to the surface layer (21), and a release state, in which the adherent coupling of the biological cells (1) to the surface layer (21) is reduced in comparison to the binding state. The invention also relates to a method for processing biological cells (1) in the bioreactor (100).
CLOSED SYSTEM DEVICE AND METHODS FOR GAS PERMEABLE CELL CULTURE PROCESS
Novel methods and apparatus are disclosed for cell culture and cell recovery. The methods and apparatus simplify the process of cell separation from media, minimize potential damage to gas permeable devices during fluid handling, and allow closed system automated cell culture and cell recovery from gas permeable devices.
COLUMN-BASED DEVICE AND METHOD FOR RETRIEVAL OF RARE CELLS BASED ON SIZE, AND USES THEREOF
A device and method for retrieving cells of interest, in particular rare cells, were disclosed. Tumor-derived endothelial cell clusters (TECCs) retrieved using the disclosed device and method can be used for the diagnosis and prognosis of cancer.
CELL THERAPY VESSELS
The present disclosure provides improved cell therapy vessels, cell therapy vessel adapters, kits, and methods of using the same.
Automated system for processing particles
A method and system for processing particles contained in a liquid biological sample is presented. The method uses a rotatable vessel for processing particles contained in a liquid biological sample. The rotatable vessel has a longitudinal axis about which the vessel is rotatable, an upper portion having a top opening for receiving the liquid containing the particles, a lower portion for holding the liquid while the rotatable vessel is resting, the lower portion having a bottom, and an intermediate portion located between the upper portion and the lower portion, the intermediate portion having a lateral collection chamber for holding the liquid while the rotatable vessel is rotating. The method employs dedicated acceleration and deceleration profiles for sedimentation and re-suspension of the particles of interest.
