A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet, and an impeller arranged in said pump casing and rotatably supported in the pump casing by a bearing so as to be rotatable about an axis of rotation. The impeller has blades for conveying blood from the blood flow inlet to the blood flow outlet. The bearing comprises at least one stationary bearing portion coupled to the pump casing and having a stationary bearing surface that faces radially outwards. The bearing further comprises a rotating bearing surface interacting with the stationary bearing surface to form the bearing, wherein the rotating bearing surface faces radially inwards and is formed on an exposed radially inner edge of the blades. The blades are designed to draw blood deposit on the stationary bearing surface in a radially outward direction.

Blood pump

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.

An implantable connector assembly () for communicating an element to an implantable device () within a patient () comprises a plug (), a receptacle (), and a pair of communication structures (). The plug () includes a plunger body (). The receptacle () includes a sleeve () and a stopper (). The sleeve () defines an opening (), and the stopper () is resiliently mounted within the sleeve () to cover and fluidly seal the opening (). The pair of communication structures () is positioned respectively on the plunger body () and the sleeve (). One of the communication structures () connects to a source and the other communication structure () connects to the implantable device (). The plunger body () inserts into the sleeve () to displace the stopper () and couple the pair of communication structures () for communication of the element therebetween.
