Artificial heart control systems and methods
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.
1. A method comprising:
receiving, by one or more processors, user input associated with a patient;
receiving, by the one or more processors, sensor data generated by one or more body sensors monitoring a body of the patient;
identifying, by the one or more processors and based at least in part on the sensor data and the user input, target operational parameters for an artificial heart;
determining, by the one or more processors and based at least in part on a control parameter model, control parameters for the artificial heart to achieve the target operational parameters, wherein the control parameter model correlates the control parameters and the target operational parameters based at least in part on the sensor data;
determining, by the one or more processors and based at least in part on the control parameters and current operational parameters of the artificial heart, a ramp rate for implementing the control parameters by the artificial heart; and
causing, by the one or more processors, the artificial heart to implement the control parameters to achieve the target operational parameters according to the ramp rate in real-time.
