Abstract
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.
Claims27
A mechanical circulatory support system comprising:
- a controller configured to generate control signals comprising at least one performance parameter and to repeatingly transmit the control signals within consecutive time periods;
- and
- an implantable blood pump communicatively coupled to the controller, the blood pump comprising:
- a rotary motor;
- and
- a control unit communicatively coupled with the rotary motor and configured to:
- receive the control signals from the controller;
- track the consecutive time periods;
- and
- retrieve at least one back-up parameter if a control signal is not received from the controller within a predetermined time or number of the consecutive time periods to ensure operation of the implantable blood pump during a communication interruption or loss.
An implantable blood pump comprising:
- a rotary motor;
- a control unit communicatively coupled with the rotary motor and configured to:
- repeatingly receive control signals comprising at least one performance parameter;
- track receipt of the control signals over a time period;
- and
- retrieve at least one back-up parameter if a control signal is not received within a predetermined time period to ensure operation of the implantable blood pump during a communication interruption or loss.
