Abstract

Official abstract text for this publication.

Methods, 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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of operating an implantable blood pump comprising a control unit, the method comprising: repeatedly receiving a control signal from a system controller with a control unit of the implantable blood pump, wherein the control signal comprises at least one blood pump performance parameter directing operation of the implantable blood pump; operating the blood pump with the control unit according to the control signal; triggering a threshold indicating absence of receipt of a new control signal from the system controller with the control unit; retrieving at least one back-up parameter from a memory in the control unit, wherein the at least one back-up parameter comprises a stored blood pump performance parameter; and operating the blood pump with the control unit according to the at least one back-up parameter. 2. The method of claim 1 , wherein the at least one back-up parameter is retrieved from memory located on the blood pump. 3. The method of claim 1 , wherein the threshold is triggered when a new control signal is not received within a predetermined time period. 4. The method of claim 3 , wherein the predetermined time period comprises at least 5 seconds. 5. The method of claim 1 , wherein the blood pump performance parameter comprises a first portion specifying a pump speed, and a second portion specifying a pulse parameter. 6. The method of claim 5 , further comprising storing the first portion of the control signal as the at least one back-up parameter. 7. The method of claim 1 , wherein when the blood pump is operating according to the at least one back-up parameter, receiving a second control signal, and operating the blood pump according to the second control signal.
