  • Intravascular blood pumps and pumps with expandable scaffolds
    Patent number: 12678612
    Abstract: Catheter blood pumps that include an expandable pump portion. The pump portions include a collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pump portion also includes one or more impellers. The collapsible scaffold may include portions of differing radial stiffness based on location of the one or more impellers therein.
    Type: Grant
    Filed: March 7, 2022
    Date of Patent: July 14, 2026
    Assignee: Supira Medical, Inc.

  • BLOOD PUMP WITH CANTILEVERED IMPELLER
    Publication number: 20250177725
    Abstract: Intravascular blood pumps systems and methods of use are provided. The blood pump system includes a catheter portion having a distal blood pump with a cantilevered collapsible impeller. The blood pump includes sections of increased stiffness and sections of increased flexibility. The blood pump is designed and configured to bend at a distal tip, a central section, and in a proximal catheter shaft, while maintaining stiffness in the inlet and outlet. Collectively the pump is designed and configured to maintain tip gap between the impeller and the blood conduit without requiring any structures in the blood conduit distal to the impeller assembly.
