Abstract

Embodiments of the disclosure include systems and methods for obtaining high-resolution data from implantable medical devices (IMDs) by triggering a limited-time system behavior change. For example, embodiments include utilizing study prescriptions for batching data obtained by an IMD, communicating the batched data to an external device, and reconstructing the batched data at the external device. Study prescriptions refer to sets of instructions, conditions, protocols, and/or the like, that specify one or more of an information gathering scheme and a communication scheme, and may be configured, for example, to obtain information at a resolution sufficient for performing a certain analysis (e.g., associated with a diagnostic model), while managing the resulting impact to device longevity and/or performance.

First claim

We claim:

1 . A system, comprising:
an implantable medical device (IMD) configured to be implanted within a patient's body, the IMD comprising:
a sensing component configured to obtain values of a first physiological parameter;
a power source configured to provide power to the IMD; and
a first communication component configured to transmit, according to a study prescription, the values of the first physiological parameter, the study prescription comprising a communication scheme that is configured based on an impact on a longevity of at least one component of the IMD; and
an external monitoring device (EMD) configured to be disposed outside of a patient's body, the EMD comprising a second communication component, configured to receive, from the first communication component, the values of the first physiological parameter.

2 . The system of claim 6 , wherein the impact on the longevity of the at least one component of the IMD corresponds to an amount of power consumption associated with the information transmission.

3 . The system of claim 6 , wherein the study prescription further includes instructions configured to cause the sensing component to store the values of the first physiological parameter.

4 . The system of claim 3 , wherein the impact on the longevity of the at least one component of the IMD corresponds to at least one of an amount of power consumption associated with obtaining the values of the first physiological parameter and storing the values of the first physiological parameter.

5 . The system of claim 3 , the IMD further comprising a trigger component configured to detect, based on a first set of information, a trigger event, wherein the first set of information comprises a set of values of a second physiological parameter.

6 . The system of claim 3 , the EMD further comprising a trigger component configured to detect, based on a first set of information, a trigger event, wherein the first set of information comprises values of a second physiological parameter.

7 . The system of claim 3 , the values of the second physiological parameter comprising additional values of the first physiological parameter.

8 . The system of claim 1 , further comprising a management server, the management server comprising a third communication component configured to communicate with the second communication component.

9 . The system of claim 8 , wherein at least one of the EMD and management server provides an analysis component configured to analyze at least the values of the first physiological parameter.

10 . The system of claim 9 , wherein the analysis component is configured to implement one or more adjudication algorithms to adjudicate a diagnosis based on the values of the first physiological parameter.

11 . The system of claim 10 , wherein at least one of the IMD, EMD, and management server implements a prescription component, the prescription component configured to enable implementation of the study prescription.

12 . The system of claim 11 , the prescription component comprising:
a study selection component configured to select a diagnostic model from among a plurality of candidate diagnostic models; and a prescription generator configured to generate the study prescription based on the selected diagnostic model.

13 . The system of claim 8 , wherein the management server further comprises a confirmation component configured to provide a notification of the study prescription to a user device, and to receive, from the user device, at least one of a confirmation of the study prescription or a modification of the study prescription.

14 . A method of managing communication of values of a first physiological parameter sensed by an implantable medical device (IMD) to an external monitoring device (EMD), the method comprising:
obtaining a first set of information, the first set of information comprising at least one value of an IMD parameter associated with power consumption; generating a study prescription, the study prescription comprising a communication scheme that is configured based on power consumption; and facilitating transmission, according to the study prescription, of the values of the first physiological parameter from the IMD to the EMD.

15 . The method of claim 14 , further comprising:
obtaining a first set of information comprising at least one value of a second physiological parameter; and detecting, based on the first set of information, a trigger event, wherein the step of generating the study prescription is performed in response to detecting the trigger event.

16 . The method of claim 15 , wherein generating the study prescription comprises:
identifying, based on the first set of information, a plurality of diagnostic models; determining, for each of the plurality of diagnostic models, one or more input options; calculating, for each of the plurality of diagnostic models, a cost associated with each of the one or more input options; selecting, based on the calculated cost associated with each of the one or more input options, one of the plurality of diagnostic models, wherein the selected diagnostic model comprises a set of inputs; establishing a set of input parameters associated with the set of inputs; and generating, based on the set of input parameters, a set of instructions configured to be executed by the IMD to implement the study prescription.

17 . A system, comprising:
an implantable medical device (IMD) configured to be implanted within a patient's body, the IMD comprising:
a sensing component configured to (1) obtain a first set of values of a first physiological parameter, and (2) obtain, according to a study prescription, a second set of values of a second physiological parameter;
a first communication component configured to transmit the first set of values of the first physiological parameter and the second set of values of the second physiological parameter; a trigger notification, the trigger notification comprising an indication of the detection of the trigger event;
an external monitoring device (EMD) configured to be disposed outside of a patient's body, the EMD comprising:
a second communication component, configured to receive, from the first communication component, the first set of values of the first physiological parameter, the second set of values of the second physiological parameter, and a first set of information, the first set of information comprising a value of at least one IMD parameter;
