1. A mechanical circulatory support system comprising:
- an implantable blood pump comprising;
a memory comprising;
first application software for controlling operation of the blood pump;
a first checksum for validating the first application software;
second application software for controlling operation of the blood pump; and
a second checksum for validating the second application;
a rotor; and
a control unit communicatively coupled with the memory and the rotor, the control unit configured to;
select the first application software;
generate a checksum for the selected first application software;
determine that the generated checksum matches the first checksum;
launch the first application software; and
control the rotor according to the first application software.

Abstract
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.

19. A method of controlling an implantable blood pump, the method comprising:
-
selecting a first application software stored in a memory of the implantable blood pump by a control unit of the implantable blood pump; generating a checksum for the first application software; retrieving a first checksum from the memory, wherein the first checksum is associated with first application software; determining with the control unit that the generated checksum matches the first checksum; launching the first application software; and controlling a rotor of the implantable blood pump according to the first application software. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
