  • Patent number: 10603665
    Abstract: A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a container defining a cavity for receiving the fluid. The container has a top, a sidewall extending from the top, and a bottom disposed opposite the top and in sealing engagement with the sidewall. An insert is slidably disposed in the cavity of the container and defines a lumen through the insert. The lumen, which includes a hole and a funnel-shaped upper portion in fluid communication with the hole, forms an open fluid path between opposite ends of the insert. The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container.

  • Patent number: 10383622
    Abstract: A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a needle driver at a distal end of the drive arm, wherein the needle driver is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the needle driver, thereby rotating the suturing needle about the rotational axis.

  • Publication number: 20190038445
    Abstract: The present invention relates to methods and articles for anchoring within a natural bodily lumen. An anchor is adapted to provide differing radially-outward forces along its length, a securing force and a transitional force. Production of these forces can be controlled by varying a physical property of the anchor, such as its stiffness, thickness, or shape. For example, the stiffness of an elongated anchor can be varied from a relatively soft value at its proximal and distal ends to a relatively stiff value at its center by varying the diameter of wire forming the anchor, thereby tailoring it to an intended application. Such force tailoring can be combined with external barbs and used to reliably anchor other instruments, such as feeding tubes and intestinal sleeves.
