Abstract

A controller for an artificial heart enables activity-specific adjustments to the operation of an artificial heart by obtaining sensor data from a plurality of sensors monitoring characteristics of a patient's body, and using the sensor data as input to one or more control parameter models for identifying control parameters to be provided to the artificial heart to adjust the operational parameters of the artificial heart. The controller is in wireless communication with the artificial heart via an application program interface (API)-based communication channel that facilitates communication between the controller and the artificial heart. Moreover, a cloud-based management computing entity may be utilized to train and/or execute one or more models to enable real-time updates to the operational characteristics of the artificial heart to enable the artificial heart to appropriately accommodate activities of the patient.

First claim

That which is claimed:

1 . A method comprising:
receiving, at an artificial heart, control parameter data to adjust operational parameters of the artificial heart based at least in part on sensor data generated by one or more sensors monitoring characteristics of a patient's body; implementing the control parameter data by adjusting the operational parameters of the artificial heart based at least in part on the control parameter data; monitoring one or more of: hardware of the artificial heart and communications received by the artificial heart to detect a trigger condition; and upon detecting a trigger condition, implementing safe mode parameters stored within a local memory storage area of the artificial heart by adjusting the operational parameters based at least in part on the safe mode parameters, wherein the safe mode parameters identify a constant flow rate of blood for implementation by the artificial heart.

2 . The method of claim 1 , wherein detecting the trigger condition comprises receiving trigger condition data at the artificial heart.

3 . The method of claim 2 , wherein the trigger condition comprises data indicating a low blood pressure measurement of the patient's body.

4 . The method of claim 1 , wherein detecting the trigger condition comprises determining that a communication channel has been disconnected from the artificial heart.

5 . The method of claim 1 , wherein detecting the trigger condition comprises detecting one or more hardware malfunctions of the artificial heart.

6 . The method of claim 1 , wherein detecting the trigger condition comprises determining that a communication channel at the artificial heart has been compromised.

7 . The method of claim 1 , further comprising:
upon determining that the trigger condition has been remedied:
receiving updated control parameter data; and
implementing the updated control parameter data by modifying the operational parameters based at least in part on the updated control parameter data.

8 . The method of claim 7 , wherein determining that the trigger condition has been remediated comprises receiving user input data identifying the trigger condition as being remedied.

9 . The method of claim 1 , further comprising:
in response to implementing the safe mode parameters, disabling the artificial heart from adjusting the operational parameters based on additional sensor data generated by the one or more sensors.
