Cell capture system and method of use
A cell capture system including an array, an inlet manifold, and an outlet manifold. The array includes a plurality of parallel pores, each pore including a chamber and a pore channel, an inlet channel fluidly connected to the chambers of the pores; an outlet channel fluidly connected to the pore channels of the pores. The inlet manifold is fluidly connected to the inlet channel, and the outlet channel is fluidly connected to the outlet channel. A cell removal tool is also disclosed, wherein the cell removal tool is configured to remove a captured cell from a pore chamber.
FLUIDIC MODULE, DEVICE AND METHOD FOR HANDLING LIQUID
A fluidic module rotatable about a center of rotation includes a first compression chamber having a fluid inlet and a fluid outlet, a second compression chamber having a fluid inlet, a first fluid channel connected to the first chamber via the fluid inlet of the first chamber, and a second fluid channel connecting the fluid outlet of the first chamber to the fluid inlet of the second chamber. Due to rotation of the fluidic module a liquid may be centrifugally driven into the first chamber and the second fluid channel through the first fluid channel, and thereby a compressible medium may be entrapped and compressed within the second chamber. By lowering the rotary frequency and due to the resultant expansion of the compressible medium, liquid may be driven out of the second fluid channel into the first chamber, out of the first chamber into and through an outlet channel.
Anchored-liquid stationary phase for separation and filtration systems
Various embodiments comprise systems, methods, architectures, mechanisms or apparatus configured to separate particles of varying size within a fluid flow, or filter particles from a fluid flow, via an array of anchored-liquid drops or anchored-gas drops.
AIR CAPILLARY VENT FOR A LATERAL FLOW ASSAY DEVICE
A lateral flow diagnostic assay device is defined by a substrate having a top surface that further includes a sample addition zone for receiving a sample, a transport and reaction zone, and a wicking zone. Each of the sample addition zone, reaction and transport zone and wicking zone are disposed on the top surface of the substrate and fluidically interconnected by means that permit lateral capillary flow along at least one fluid flow path from the sample addition zone to the wicking zone. The assay device further includes a capillary vent disposed in relation to the wicking zone, the capillary vent having an overall length and cross sectional area that creates a backpressure so as to control the flow rate of a sample applied to the assay device.
Point of care test cartridge
A test cartridge for evaluating biological fluids can have a sensor flow cell defining a flow path for selectively passing a test fluid or biological fluid across a sensor to evaluate the sensor or the biological fluid. The test cartridge can include a sample port and at least one deformable reservoir, both formed as part of the test cartridge and fluidly connected to the flow path upstream of the sensor. A biological fluid can be manually fed into the flow path through the sample port for evaluation by the sensor. Before the biological fluid is fed through the sample port, the deformable reservoir can be manually ruptured to pass the test fluid contained within the reservoir across the sensor to first evaluate the sensor. In an example, the deformable reservoir can include a first reservoir containing a liquid quality control (LQC) fluid and a second reservoir containing a calibration fluid.
Apparatus for and methods of processing liquids or liquid-based substances
Apparatus for processing liquids or liquid-based substances includes a plurality of volumes at least two of which are defined at least in part by one or more phaseguides inside the volume and/or in a conduit connected thereto for controlling aliquoting of one or more liquids or liquid-based substances inside the volume. Each volume has an upstream and downstream side with respect to meniscus advancement direction via which it may be filled with or emptied of one or more liquids or liquid-based substances. The apparatus also includes at least one common upstream-side conduit connected to supply a liquid or liquid-based substance via a plurality of the inlet or extraction conduits, a plurality of the phaseguides exhibiting a predetermined level of stability and one or more of the phaseguides exhibiting a predetermined different stability compared with the stability of at least one of the other phaseguides whereby to control the preference order in which the volumes fill and/or empty. The stability is determined by the value and radius of an acute angle along a said phaseguide at the downstream side of the phaseguide.
Apparatus and methods for accessing and dilating bone structures using a narrow gauge cannula
Systems, apparatus and methods are disclosed for medical treatment comprising bone access and dilatation and/or cavity creation or enlargement using a narrow gauge, preferably 11-gauge or smaller, cannula wherein a catheter/expandable element assembly meeting medical protocols is designed, adapted and fabricated to fit through the interior of the associated 11-gauge or smaller cannula.
Device and methods using porous media in fluidic devices
A system that incorporates teachings of the subject disclosure may include, for example, a process that includes obtaining a porous medium comprising a porous material having a first shape and an initial porosity profile. The porous medium is engaged with a cavity in a fluidic device, wherein the cavity is in fluid communication with a channel of the fluidic device. The first shape of the porous material can be adjusted to a second shape resulting in the initial porosity profile being adjusted to a target porosity profile. Such adjustment can be accomplished by the engaging of the porous medium with the cavity, by pre-adjusting a shape of the porous media before insertion into the cavity, or by some combination thereof. Other embodiments are disclosed.
MICRO LIQUID TRANSFER STRUCTURE AND ANALYSIS DEVICE
A micro liquid transfer structure includes a plurality of micro projections arranged at intervals causing a capillary action, wherein the plurality of micro projections form periodically arranged unit rows, wherein each of the unit rows comprises the micro projections arranged in one row; and liquid transfer paths that are gaps between the micro projections, wherein at least one of the liquid transfer paths is a low flow resistance liquid transfer path having a flow resistance lower than flow resistances of the other liquid transfer paths, and wherein the low flow resistance liquid transfer path is disposed along a predetermined liquid transfer direction.
System and method for integrated multiplexed photometry module
Microfluidic cuvettes and a network of multiplexed channels including such cuvettes. The channels operationally share a main output channel defining an output of the network. A microfluidic channel includes an inlet, a cuvette, and an outlet that is coupled into the main output channel. The network is configured to provide a difference in resistances, to the fluid, by the main output channel and by an individual outlet is sufficient to prevent cross-contamination of different cuvettes, thereby operably isolating individual channels from one another. An individual cuvette is adapted to substantially prevent the formation of air-bubbles as part of the fluid flow through the cuvette and, therefore, to be fully filled and fully emptied. A system and method for photometric measurements of multiple fluid samples employing such network of channels.
