  • Patent number: 11976316
    Abstract: Phenotyping of cells involves loading a biological sample into a microfluidic device (1, 100) comprising cell compartments (20, 120) to capture biological material, including target cells, in the sample in the cell compartments (20, 120). A subset (20A) of the cell compartments (20, 120) is identified as comprising target cells exhibiting target phenotype characteristic(s) as determined based on monitoring biological material in the cell compartments (20, 120) prior to addition of a test agent. The biological material is exposed to a test agent and a phenotypic response of the target cells to the test agent is determined based on monitoring target cells in the identified subset (20A) of the cell compartments (20, 120). The phenotyping of the target cells is thereby not overshadowed by the response of other cells and non-cell material present in the biological sample.

  • Patent number: 11958049
    Abstract: A sample loading cartridge (1) for a microfluidic device comprises a cartridge body (10) with a sample reservoir (20) configured to house a volume of a liquid sample (3) and a sample port (30) in connection with the sample reservoir (20). The cartridge (1) also comprises an output channel (40) extending from the sample reservoir (20) and a feedback channel (50) connected to the sample reservoir (20) and to the sample port (30). The cartridge body (10) comprises a detection portion (60) aligned with the feedback channel (50) to enable detection of any sample (3) in the feedback channel (50). The flow resistance of the feedback channel (50) is lower than the flow resistance of the output channel (40) to cause liquid sample (3) received in the sample port (30) to enter the feedback channel (50) with substantially no liquid sample (3) entering the output channel (40).

  • Patent number: 11414552
    Abstract: An antibacterial device is disclosed that includes a substrate and an antibacterial coating or antibacterial surface being provided on at least a part of the substrate's surface. The antibacterial coating or surface includes Angstrom scale flakes, where the Angstrom scale flakes are arranged in a standing position on the substrate surface and are attached to the substrate surface via edge sides thereof. The Angstrom scale flakes can, for example, be graphene flakes, or graphite flakes having a thickness of a few atom layers. It has been found that such standing flakes are efficient in killing prokaryotic cells but do not harm eukaryotic cells.

  • Publication number: 20210260333
    Abstract: Improved urinary catheters are described. One example urinary catheter includes a catheter shaft with an internal lumen, extending between a distal discharge opening and a proximal drainage opening, arranged at a proximal tip of the catheter shaft. An overcoat layer encircles a portion of the catheter shaft, forming a closed deformable fluid filled cavity intermediate the overcoat layer and the outer surface of the shaft. The overcoat layer is elastically deformable to allow for movement of the fluid within the cavity during deployment. At least a portion at the proximal end is arranged to be compressed to a smaller diameter during insertion, and upon continued insertion of the catheter shaft through the urethra into at least the bladder neck, arranged to expand back toward a greater diameter, as the fluid is caused to flow toward the proximal end of the fluid filled cavity.

    Abstract: A urinary catheter and a method of its manufacture are disclosed. The urinary catheter comprises a tubular shaft extending between an insertion end and a discharge end, the tubular shaft being formed of at least two materials having different properties. The materials are arranged substantially separated from each other in distinct zones, wherein at least one of the width and thickness of said zones varies over the length of the tubular shaft, to form two or more uniform sections of the tubular shaft having various relative amounts of said materials, and wherein at least one transition between two such uniform sections is formed by at least one transition section providing a gradual transition between the uniform sections. The catheter can e.g. be produced by intermittent extrusion.

  • Publication number: 20210008554
    Abstract: A capturing of target cells from a biological sample is achieved by inducing a flow of the biological sample in a flow channel (30, 60) of an upstream microfluidic device (1). Target cells present in the biological sample are captured in cell channels (20) of the upstream microfluidic device(1). Once at least a minimum number of target cells are captured in the cell channels (20), the flow of the biological sample in the flow channel is reduced and are verse flow is applied at the upstream microfluidic device (1) to release the target cells captured in the cell channels (20) of the upstream microfluidic device (1) and enable transfer the target cells into cell channels (120) of a downstream microfluidic device (100).
