1. A mechanical circulatory support system, comprising:
- an implantable blood pump comprising a rotary motor and impeller blades rotated by the rotary motor to pump blood; and
an implantable control unit that controls operation of the implantable blood pump, the implantable control unit including a memory storing software applications executable by the implantable control unit, at least one of the software applications stored in the memory being configured to control operation of the implantable blood pump, the implantable control unit being configured to effect an update process in which the implantable control unit receives an update software application, selects one of the software applications stored in the memory to be replaced by the update software application, and stores the update software application in the memory in place of the selected one of the software applications.

Abstract
Methods, systems, and devices for an updatable 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 system controller can initiate the update process and can provide the update to the blood pump. Upon initiation of the update process, the control unit can stop the rotary motor. While the rotary motor is stopped, the blood pump can be updated. At the completion of the update, the rotary pump can be restarted.
