  • Publication number: 20250135184
    Abstract: Devices for moving blood within a patient, and methods of doing so. The devices can include a pump portion that includes an impeller and a housing around the impeller, as well as a fluid lumen. The impeller can be activated to cause rotation of the impeller and thereby move fluid within the fluid lumen.

  • Publication number: 20250135183
    Abstract: Catheter blood pumps that include an expandable conduit coupled to at least one hub shaped to promote smooth blood flow. In some examples, the at least one hub includes a body with radially extending arms that are coupled to struts of the conduit. The hub may include channels having curved surfaces for promoting non-turbulent fluid flow around a distal opening and/or a proximal opening of the conduit. The arms may have ridge regions that extend axially along the body of the hub to define at least a portion of the channels.

  • Publication number: 20250114591
    Abstract: Catheter blood pumps that include an expandable conduit coupled to at least one hub shaped to promote smooth blood flow. In some examples, the at least one hub includes non-metallic configuration and the struts comprise a metallic configuration (e.g., nitinol). The hub can include one or more layers, including a combination of Chronoflex and Pebax.

  • Publication number: 20250032771
    Abstract: Catheter blood pumps that include an expandable blood conduit and at least one impeller. Tension members extending from the blood conduit are associated with increasing a stiffness of an impeller region housing the impeller, thereby increasing the impeller region's resistance to deflection, and maintaining clearance for the impeller. In some cases, a tension control element is used to control a degree of tension placed on the tension members. The tension control element may be used to increase or decrease the stiffness of the impeller region and/or modulate the size of a blood inlet or outlet of the blood conduit.
