  • Patent number: 11986299
    Abstract: Methods and systems are provided for point-of-care nucleic acid amplification and detection. One embodiment of the point-of-care molecular diagnostic system includes a cartridge and an instrument. The cartridge can accept a biological sample, such as a urine or blood sample. The cartridge, which can comprise one or more of a loading module, lysis module, purification module and amplification module, is inserted into the instrument which acts upon the cartridge to facilitate various sample processing steps that occur in order to perform a molecular diagnostic test.
    Type: Grant
    Filed: November 2, 2020
    Date of Patent: May 21, 2024
    Assignee: Talis Biomedical Corporation
    Inventors: Sayeed Andeshmand, Thomas H. Cauley, III, John Dixon, David Glade, Hédia Maamar, Michael John McAdams, Dzam-Si Jesse Ng, David Alexander Rolfe

  • Patent number: 10898895
    Abstract: This disclosure relates to an assembly for loading a sample liquid. The assembly comprises an entry port comprising an inlet and a gas vent, and a reservoir. The reservoir comprises a distal wall, a fin, and a continuous fluidic pathway. The fin comprises first and second surfaces and extends from the inlet towards the distal wall. The continuous fluidic pathway comprises a converging channel that is in fluidic communication with the inlet and is defined by the second surface of the fin, and a diverging channel that is defined by the first surface of the fin and is in fluidic communication with the gas vent. At a distal end of the fin, a width of the converging channel at most equals a width of the diverging channel, and the width of the converging channel at most equals a distance between the distal end of the fin and the distal wall.
