Disclosed are systems, devices, and methods that employ a pump to assist or support blood flow. An apparatus for pumping blood may include a pump housing having an outer wall disposed about a longitudinal pump axis, and having an upstream end and a downstream end; a blood flow straightener having a plurality of fins and positioned in the upstream end of the pump housing and secured to the pump housing by the plurality of fins; a diffuser having a plurality of diffuser fins and positioned in the downstream end of the pump housing and secured to the pump housing by the plurality of diffuser fins; and an impeller positioned between the blood flow straightener and the diffuser, and including a plurality of impeller blades. The apparatus may further include a pump drive configured to impart a rotational motion to the impeller by applying a magnetic field.

Systems and methods for pump-assisted blood circulation

A system for cleaning an implanted blood pump, comprising: an inflow catheter having an expandable inflow member positioned about the periphery thereof; an inflow tube coupled with the inflow catheter; a valve assembly coupled to the inflow tube; an outflow tube coupled to the valve assembly; and an outflow catheter having an expandable outflow member positioned about the periphery thereof, the outflow catheter being coupled to the outflow tube. In use, the inflow tube and outflow tube extend through the skin of a human body, the inflow catheter and outflow catheter are positioned within the human body, and the valve assembly is positioned outside the human body.

Pump clean-out system

A blood pump having a rotor and a stator, in which the rotor has a filled core channel and a plurality of filled radial channels configured to maximize the communication of magnetic flux.

Implantable blood pump

A blood flow calibration systemincluding a computeroperable to determine and store calibration data for a flow meter, a test systemoperable to simulate blood flow for the flow meter, thereby allowing the computerto determine the calibration data, and a programmeroperable to transfer the calibration data from the computerto the flow meter. The flow meterpreferably includes a power management circuitoperable to detect whether the flow meteris powered. In the event that the flow meteris unpowered, the power management circuitis preferably able to supply power to a portion of the flow meterin order to transfer the calibration data thereto.

A controller module for an implantable pump system which has a pump motor includes a processor, a motor controller electrically coupled to the processor and adapted to power the pump motor such that the pump motor operates at a desired speed. The motor controller outputs digital representations of the pump motor operating parameters to the processor. A first memory device is coupled to the processor for storing the digital signals representing the pump motor operating parameters. The controller module further includes a user interface. The controller module may be coupled to a data acquisition system, which provides power and exchanges data with the controller module. The controller module may alternately be coupled to a home support system which provides power for the controller module and storage for system components.

Implantable pump system

The present invention relates to a pulsatile flow system and method. The pulsatile flow system includes a reservoir, a pressure riser and a first fluid passage connected between the reservoir and the pressure riser. The system further includes a device adapted to expel fluid from the reservoir through the first fluid passage to the pressure riser. A second fluid passage is connected between the pressure riser and the reservoir, and is adapted to allow fluid to flow unidirectionally therethrough, from the pressure riser to the reservoir. The pulsatile flow system may be adapted to provide pulsatile fluid flow through a medical device, such as a ventricle assist device or mechanical heart valve, to replicate a heart's pumping action for testing the device.
