## Abstract

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.

## Claims

### Claim 1

A method comprising:
translating, to an offline mode, a remote controller coupled to an implantable blood pump having an implantable controller, wherein the implantable blood pump is coupled to a pump driveline including a pump connector, wherein the pump connector is coupled to a system update connector, and wherein the system update connector is coupled to a power source;
updating the remote controller in the offline mode, the update including at least one of a group including a remote controller exchange and a remote controller update, wherein the power source coupled to the system update connector continuously provides power to the implantable blood pump during the updating of the remote controller; and
maintaining the implantable blood pump in an operative mode during the updating of the remote controller.

### Claim 2 (depends on 1)

The method of claim 1, further comprising programming the implantable controller to perform a motor control function.

### Claim 3 (depends on 1)

The method of claim 1, further comprising coupling a controller connector having a controller driveline to the pump connector.

### Claim 4 (depends on 3)

The method of claim 3, further comprising coupling the controller connector to a first receiving portion of the pump connector and coupling the system update connector to a second receiving portion of the pump connector, the system update connector and the pump connector being coupled to each other using a magnetic force.

### Claim 5 (depends on 1)

The method of claim 1, wherein the pump driveline includes a data network connection having a bi-directional communication pathway between the implantable controller and the remote controller.

### Claim 6 (depends on 1)

The method of claim 1, further comprising translating the remote controller to an online mode from the offline mode and disconnecting the system update connector from the pump connector.
