Abstract
A medical device may receive sensor data from sensing sources, and determine confidence levels for sensor data received from each of the plurality of sensing sources. Each of the confidence levels of the sensor data from each of the sensing sources is a measure of accuracy of the sensor data received from respective sensing sources. The medical device may also determine one or more therapy parameter values based on the determined confidence levels, and cause delivery of therapy based on the determined one or more therapy parameter values.
Claims26
A method of therapy delivery, the method comprising:
- receiving sensor data generated by plurality of hardware sensing sources;
- determining a control policy to utilize for determining one or more therapy parameter values based on the received sensor data, wherein the control policy is one of a plurality of control policies in a hierarchical arrangement, and each of the control policies is associated with a respective set of one or more conditions and respective one or more therapy parameter values;
- determining one or more therapy parameter values based on the respective one or more therapy parameter values associated with the determined control policy;
- and
- causing delivery of therapy based on the determined one or more therapy parameter values.
A medical system for therapy delivery, the medical system comprising:
- a plurality of hardware sensing sources configured to generate sensor data;
- and
- a processing circuit configured to:
- receive sensor data generated by plurality of hardware sensing sources;
- determine a control policy to utilize for determining one or more therapy parameter values based on the received sensor data, wherein the control policy is one of a plurality of control policies in a hierarchical arrangement, and each of the control policies is associated with a respective set of one or more conditions and respective one or more therapy parameter values;
- determine one or more therapy parameter values based on the respective one or more therapy parameter values associated with the determined control policy;
- and
- cause delivery of therapy based on the determined one or more therapy parameter values.
A computer-readable storage medium storing instructions thereon that when executed cause one or more processors to:
- receive sensor data generated by plurality of hardware sensing sources;
- determine a control policy to utilize for determining one or more therapy parameter values based on the received sensor data, wherein the control policy is one of a plurality of control policies in a hierarchical arrangement, and each of the control policies is associated with a respective set of one or more conditions and respective one or more therapy parameter values;
- determine one or more therapy parameter values based on the respective one or more therapy parameter values associated with the determined control policy;
- and
- cause delivery of therapy based on the determined one or more therapy parameter values.
