A remote controller updating system for an implantable blood pump including an implantable blood pump, an implantable controller coupled to the implantable blood pump, and a pump driveline including a data network connection in communication with the implantable controller. The system may also include a pump connector coupled to the pump driveline, a remote controller couplable to the implantable blood pump, and a system update assembly including a system update connector couplable to the pump connector and a power source coupled to the system update connector.

Updating a VAD system without stopping the pump

A method of controlling an implantable blood pump including a housing having a proximal portion including an inlet, a distal portion including an outlet, and an impeller therein, the method including detecting when a pressure in the housing exceeds a pressure threshold and executing a first vector control command to displace the impeller axially in a distal direction from a primary position to a secondary position different than the primary position in response to the pressure exceeding the pressure threshold.

Axial pump pressure algorithm with field oriented control

A method of controlling a blood pump including executing a control command to temporarily displace an impeller of the blood pump within a pump housing from a first axial position relative to the pump housing to a second axial position a distance away from the first axial position using a vector control method, and causing the impeller to move from the second axial position to a third axial position, the third axial position including a positive and a negative displacement of the impeller relative to the first axial position.

Axial blood pump with impeller rinse operation

A combination baseball style cap and light assembly, wherein the cap has a crown, a bill extending from the crown, a sweatband liner circumscribing the bottom edge of the cap, and a reinforcing crown liner, has a double light and switch assembly comprising two lamp sockets affixed to a mounting plate on each side of a sealed sub-mini micro switch also affixed to the mounting plate. The plate is in turn affixed to the underside of the bill of the cap, two lamp sockets affixed to the mounting plate such that their axes decline at an acute angle to the plane of the plate and converge at an acute angle to a line perpendicular to the front edge of the plate, setting the focal point of the lamps at a predetermined location directly out from and generally equidistant between the wearers eyes. A micro switch is affixed to an integral mounting flange on the mounting plate located approximately on the center line of the mounting plate between the two sockets. First and second battery holders are each affixed respectively to each side of the center line of the top edge of the reinforcing element of the crown of the cap and the top edge of the crown of the cap, and a circuit electrically couples the micro switch, the lamp sockets and the battery holders.
