Connectors and related methods for fluidly coupling a blood pump with an aorta facilitate implantation of the blood pump. A method of fluidly coupling a blood pump with an aorta includes positioning a connector device defining a passageway extending between a proximal opening and a distal opening. The connector device includes a support member surrounding the distal opening. The support member is interfaced with a wall of the aorta so that the distal opening is at a desired location of an inlet opening in the aorta. The support member is attached to the aorta around the distal opening so as to form a fluid seal and stabilize the connector device. A slit is incised in the wall of the aorta to form the inlet opening in the aorta. A proximal opening of the tubular connector is fluidly coupled with an outflow graft tube of the blood pump.

A controller for an artificial heart enables activity-specific adjustments to the operation of an artificial heart by obtaining sensor data from a plurality of sensors monitoring characteristics of a patient's body, and using the sensor data as input to one or more control parameter models for identifying control parameters to be provided to the artificial heart to adjust the operational parameters of the artificial heart. The controller is in wireless communication with the artificial heart via an application program interface (API)-based communication channel that facilitates communication between the controller and the artificial heart. Moreover, a cloud-based management computing entity may be utilized to train and/or execute one or more models to enable real-time updates to the operational characteristics of the artificial heart to enable the artificial heart to appropriately accommodate activities of the patient.

A magnetic bearing contactlessly supporting a rotor by magnetic force includes: a bearing rotor member made of a magnetic material; and a bearing stator member arranged around bearing rotor member. The bearing stator member includes a core made of a magnetic material and a coil wound around the core. A longitudinal cross-sectional shape of the core has a first part extending in a first direction orthogonal to a direction opposed to the bearing rotor member and wound around with the coil, a pair of second parts extending from both end portions in the first direction of first part to the bearing rotor member side and subsequently extending in a direction approaching each other in the first direction, and a pair of third parts extending from respective distal end portions of the pair of second parts toward the bearing rotor member side. The bearing rotor member also includes a permanent magnet.

Methods and apparatuses for determining operational parameters of a blood pump comprising a rotor which transports the blood are provided. The change in the behaviour of at least one first and one second operational parameter, independently from each other, of the pump, is determined. A determination of the flow through the pump and/or the difference in pressure across the pump and/or the viscosity of the blood takes into account the determined change in behaviour of the at least two operational parameters. A modelling for a dynamic model of the known quantities may be carried out and an estimation method using a Kalman filter may be used.

A blood pumping device is described having at least a first pump and a first pump actuator for inducing a blood flow in a body's circulatory system. The pump has one upper chamber having an inlet channel and one lower chamber having an outlet channel. The upper and lower chambers are separated by a movable valve plane provided with a one-way valve. The pump actuator induces movement of the valve plane in an upward and downward direction between the upper and lower chambers in response to control signals from a control unit. When the valve plane moves in an upward direction, the valve opens allowing a flow of blood from the upper to the lower chamber. The lower chamber is provided with a bag-like portion forcing said flow of blood to make a turn of between 110° to 150° before leaving through the outlet channel.
