  • CELL RETENTION DEVICE
    Publication number: 20240009625
    Abstract: A cell retention device includes a structured support with a plurality of circumferentially distributed ribs to retain the active filtering surface of a flexible, porous membrane filter medium. The filter medium surrounds the support in contact with the peaks of the ribs, thereby forming axial voids between the rib peaks. This arrangement imparts sufficient structural support over small regions of the filter medium to facilitate its use in a circular (or other rounded) configuration while providing sufficient channel volume to support high throughput of fluid sparse of cells.
    Type: Application
    Filed: September 21, 2023
    Publication date: January 11, 2024
    Applicant: Sunflower Therapeutics, PBC
    Inventors: Andrew BANCHIERI, Flora LIU, Marc Miller GRAHAM

  • Laparoscopic handpiece for waveguides
    Patent number: 10426546
    Abstract: An articulating instrument including a distal assembly having first and second configurations and intermediate configurations between them. At least one of the first and second configurations is substantially stable such that the distal assembly of the instrument has a tendency to remain in the stable configuration when placed in that configuration by a user of the instrument. Preferably, the distal assembly terminates in a distal tip unit defining at least one distal feature that is useful for manipulating tissue.
