Abstract: A blood pump including a housing defining a proximal end, a distal end, and a first axis extending from the proximal end to the distal end. A ferromagnetic rotor is disposed within the housing and configured pump blood in a direction along the first axis. A stator is disposed within housing and around the ferromagnetic rotor, the stator is configured to apply a magnetic force causing rotation of the ferromagnetic rotor, the stator being eccentric to the rotor.

Abstract: Methods, systems, and devices for an adaptable blood pump are disclosed herein. The blood pump can be part of a mechanical circulatory support system that can include a system controller and the blood pump. The blood pump can include a rotary motor and a control unit that can communicate with the system controller. The blood pump can determine when communication with the system controller is established or has been lost. The blood pump can retrieve one or several back-up parameters when communication with the system controller has been lost, and can operate according to these back-up parameters.

Abstract: A heart assist device comprising a rotary pump housing having a cylindrical bore, a pumping chamber and a motor stator including an electrically conductive coil located within the housing and surrounding a portion of the cylindrical bore. A rotor has a cylindrical shaft, at least one impeller appended to one end of the shaft, and a plurality of magnets located within the shaft. The rotor shaft is positioned within the housing bore with the magnets opposite the motor stator, and the impeller is positioned within the pumping chamber. The housing bore is closely fitted to the outer surface of the shaft forming a hydrodynamic journal bearing, with the pumping chamber and journal bearing connected by a leak path of blood flow between the pumping chamber and the journal bearing. A backiron of the motor stator attracts the rotor magnets to resist longitudinal displacement of the rotor within the housing during operation. The relative orientation of positions of the inflow, outflow, and leakage flow paths may be varied within the pump, such as to accommodate different intended methods for implantation and/or use.

Abstract: A ventricular assist device includes a pump such as an axial flow pump, an outflow cannula connected to the outlet of the pump, and an anchor element. The anchor element is physically connected to the pump, as by an elongated element. The pump is implanted within the left ventricle with the outflow cannula projecting through the aortic valve but desirably terminating short of the aortic arch. The anchor element is fixed to the wall of the heart near the apex of the heart so that the anchor element holds the pump and outflow cannula in position.

The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate. The motor assembly can also comprise a stator assembly disposed about the rotor. The motor assembly can also include a heat exchanger disposed about the stator assembly, the heat exchanger may be configured to direct heat radially outward away from the stator assembly, the rotor, and the chamber.

Abstract: The present invention relates to a rotary blood pump with a double pivot contact bearing system with an operating range between about 50 mL/min and about 1500 mL/min. The rotary blood pump is part of a blood pump system that includes blood conduit(s), a control system with optional sensors, and a power source. Embodiments of the present invention may include elements such as wear resistant bearing materials, a rotor back plate for magnetic attraction of the rotor to reduce bearing pivot bearing forces and wear, a rotor size and shape and a bearing gap that combine to create a hydrodynamic bearing effect and reduce bearing pivot bearing forces and wear, improved intravascular conduits with increased resistance to thrombosis, conduit insertion site cuffs to resist infection, and conduit side ports amenable to the easy insertion of guidewire and catheter-based medical devices.
