Abstract

A Medical Device Application (MDA) is disclosed for an external device (e.g., a cell phone) that can communicate with an Implantable Medical Device (IMD). The MDA receives data logged in the IMD, processes that data in manners reviewable by an IMD patient, and that can control the IMD based on such processed data. The MDA can use the logged data to adjust IMD therapy based on patient activity or posture, and allows a patient to learn optimal therapy settings for particular activities. The MDA can also use the logged data to allow a patient to review details about IMD battery performance, whether such battery is primary or rechargeable, and to control stimulation parameters based on that performance. The MDA also allows a patient to enter medicine dose information, to review the relationship between medicinal therapy and IMD therapy, and to adjust IMD therapy based on the dosing information.

Claims

1. A system, comprising:

an implantable medical device (IMD); and

a machine-readable medium configured to be executed on an external device in wireless communication with the IMD and storing instructions to cause control circuitry in the external device to;

associate values of one or more therapy parameters and one or more patient activity parameters of the IMD with an activity of a user by;

recording a time period during which the user engaged in the activity;

receiving data logged in the IMD, wherein the logged data comprises time-stamped values of the one or more therapy parameters and the one or more patient activity parameters; and

associating the values of the one or more therapy parameters and the one or more patient activity parameters that occurred during the time period with the activity;

determine an optimal value for each of the one or more therapy parameters from the values associated with the activity; and

transmit the optimal value for each of the one or more therapy parameters to the IMD when it is determined that the user is engaging in the activity.

2. The system of claim 1, wherein the machine-readable medium further comprises instructions to cause the control circuitry to provide a graphical user interface (GUI) that includes one or more selectable activities.

3. The system of claim 2, wherein the instructions to cause the control circuitry to associate the values of the one or more therapy parameters with the activity comprise instructions to cause the control circuitry to receive an input of a selection of the activity via the GUI.

4. The system of claim 1, wherein the one or more therapy parameters comprise at least one of intensity, frequency, pulse width, and active electrodes for stimulation delivered by the IMD.

5. The system of claim 1, wherein the instructions to cause the control circuitry to determine the optimal value for each of the one or more therapy parameters comprise instructions to cause the control circuitry to determine an average of the values of the one or more therapy parameters associated with the activity.

7. The system of claim 1, wherein the values of the one or more patient activity parameters comprise measurements from an accelerometer in the IMD.

8. The system of claim 1, wherein the values of the one or more patient activity parameters comprise electrode impedance measurements.

9. The system of claim 1, wherein the instructions to cause the control circuitry to transmit the optimal value for each of the one or more therapy parameters comprise instructions to cause the control circuitry to transmit the optimal value for each of the one or more therapy parameters automatically when it is determined from the one or more patient activity parameters that the user is engaging in the activity.

10. A non-transitory machine-readable medium configured to be executed on an external device in wireless communication with an implantable medical device (IMD) and storing instructions to cause control circuitry in the external device to:
