  • Publication number: 20160193396
    Abstract: An implantable blood pump includes an impeller rotatable about a rotational axis, having a body with a bottom surface at a downstream end and a central opening centered about the axis extending at least partially through the body from the bottom surface. A projecting element, e.g., a shaft, extends from below the bottom surface into or through the opening to support the impeller. The body can be configured to drive a primary downstream blood flow along an exterior of the body to beyond a peripheral edge of the bottom surface, and to provide a secondary downstream blood flow through the opening and along the bottom surface to beyond the peripheral edge, the secondary flow improving washing of a bearing surface.

  • Publication number: 20150250933
    Abstract: An implantable connector assembly (14) for communicating an element to an implantable device (12) within a patient (20) comprises a plug (16), a receptacle (18), and a pair of communication structures (72, 108). The plug (16) includes a plunger body (64). The receptacle (18) includes a sleeve (98) and a stopper (114). The sleeve (98) defines an opening (104), and the stopper (114) is resiliently mounted within the sleeve (98) to cover and fluidly seal the opening (104). The pair of communication structures (72, 108) is positioned respectively on the plunger body (64) and the sleeve (98). One of the communication structures (72, 108) connects to a source and the other communication structure (108, 72) connects to the implantable device (12). The plunger body (64) inserts into the sleeve (98) to displace the stopper (114) and couple the pair of communication structures (72, 108) for communication of the element therebetween.

  • Publication number: 20140303427
    Abstract: A system for pumping blood in a patient comprises multiple components including a rotational drive assembly; a fluid drive element; a housing, an inflow cannula assembly and an outflow graft assembly. The inflow cannula assembly comprises an inflow conduit and an inflow connector. The outlet graft assembly comprises an outflow conduit and an outflow connector. The housing surrounds the fluid drive element and comprises an inflow port and an outflow port. The inflow conduit comprises a first end operably attachable to the inflow port and a second end fluidly connectable to a source of oxygenated blood. The outflow conduit comprises a first end operably attachable to the outflow port and a second end fluidly connectable to a blood vessel. The inflow connector operably connects the inflow conduit to the inflow port. The outflow connector operably connects the outflow conduit to the outflow port.
