  • Publication number: 20210262462
    Abstract: A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.

  • Patent number: 11096644
    Abstract: A method and system for producing tomosynthetic images of a patient's breast. An x-ray source that delivers x-rays through a breast immobilized and compressed between a compression paddle and a breast platform and form an image at a digital x-ray receptor panel. Multiple x-ray images are taken as the x-ray source and the receptor move relative to the immobilized breast. In one preferred embodiment, the x-ray source travels from ?15° to +15°. The source can travel in an arc around the breast while the receptor travels linearly while remaining parallel and at the same distance from the breast platform. The sets of x-ray image data taken at different angles are combined to form tomosynthetic images that can be viewed in different formats, alone or as an adjunct to conventional mammograms.

  • Patent number: 11076820
    Abstract: A tomosynthesis system has an x-ray source with an addressable array of electron emitting sections on the cathode. The x-ray source moves rotationally about an imaging target, such as a breast. During the rotation, x-rays are emitting from the x-ray source while the x-ray source continues to move. During the emission of x-rays, different subsets of electron-emitting sections of the addressable array are activated to compensate for movement of the x-ray source. By activating the different subsets of electron-emitting sections, an effective focal spot of the x-ray position appears to retain the same shape, size, and position from the perspective of the imaging target, despite movement of the x-ray source itself.

  • Publication number: 20210220522
    Abstract: Methods and devices for facilitating post-resection tissue formation to accelerate healing are provided. A hydrogel scaffold with encapsulated cells may be prepared. The encapsulated cells may be cells of the patient undergoing the resection that correspond to a type of the tissue resected. The hydrogel scaffold may be integrated with a frame to form an implantable device for insertion into a cavity created by the resection. The hydrogel scaffold and the frame may be bioabsorbable, and the frame may include non-bioabsorbable, radiopaque markers spaced along the frame. Upon insertion of the implantable device into the cavity, the encapsulated cells may interact with native cells to facilitate new tissue formation within the hydrogel scaffold and other areas of the cavity, the frame may provide temporary structural support for the cavity to reduce deformations as new tissue is being formed, and the markers may enable identification of the resection site.
