Abstract

An interactive implantable medical device system includes an implantable medical device and a network-enabled external device capable of bi-directional communication and interaction with the implantable medical device. The external device is programmed to interact with other similarly-enabled devices. The system facilitates improved patient care by eliminating unnecessary geographic limitations on implantable medical device interrogation and programming, and by allowing patients, physicians, and other users to access medical records, history, and information and to receive status and care-related alerts and messages anywhere there is access to a communications network.

First claim

The invention claimed is:

1. An external apparatus comprising:
a communication subsystem configured to establish a wireless communication link with an implanted device; and
a controller configured to:
receive a request to allow an action with the implanted device to occur,
determine if the implanted device is authenticated,
allow the action when the implanted device is authenticated and an elapsed time requirement is met, and
deny the action until the implanted device becomes authenticated.

2. The external apparatus of claim 1 , wherein the controller is configured to allow one or more authentication retries when the implanted device is not authenticated or the elapsed time requirement is not met.

3. The external apparatus of claim 1 , wherein the controller is configured to authenticate the implanted device based on an authentication code received from the implanted device.

4. The external apparatus of claim 1 , wherein the controller is configured to authenticate the implanted device based on biometric information.

5. The external apparatus of claim 1 , wherein the action with the implanted device comprises at least one of uploading stored data from the implanted device to the external apparatus, downloading new software code from the external apparatus to the implanted device, downloading a new parameter set from the external apparatus to the implanted device, and receiving real-time EEG signals sensed by the implanted device.

6. An external apparatus comprising:
a communication subsystem configured to establish a communication link with an implanted device; and
a controller configured to:
receive a request to allow an action with the implanted device to occur,
allow the action to occur when a time restriction related to a past request to perform the action is met, and
deny the action when the time restriction related to a past request to perform the action is not met.

7. The external apparatus of claim 6 , wherein the time restriction is based on a frequency of past requests to perform the action and a nature of the action.

8. The external apparatus of claim 6 , wherein the time restriction comprises a restriction time period, and the controller is configured to determine if the time restriction is met by being further configured to:
determine a difference between a current time corresponding to the time of the request to perform the action, and a past time corresponding to the time of a most recent past request to perform the action;
wherein the time restriction is determined to be met when the difference is at least equal to the restriction time period, and not to be met when the difference is less than the restriction time period.

9. An external apparatus comprising:
a communication subsystem configured to establish a communication link with an implanted device implanted in a patient; and
a controller configured to:
determine whether the patient is susceptible to seizures based on an evaluation of EEG data of the patient that was previously uploaded to the external apparatus,
output a command to the implanted device through the communication link, to initiate real-time monitoring of EEG signals by the implanted device when it is determined that the patient is susceptible to seizures,
receive data from the implanted device through the communication link, the data corresponding to real-time EEG signals of the patient, and
process the received data and display the received data as a real-time EEG waveform.

10. The external apparatus of claim 9 , wherein the controller is further configured to:
receive a request to output the command to the implanted device to initiate real-time monitoring of EEG signals, and
output the command only when a time restriction related to a past request to output the command is met.

11. The external apparatus of claim 9 , wherein the controller is further configured to:
receive a request to output the command to the implanted device to initiate real-time monitoring of EEG signals, and
output the command only when the implanted device is authenticated and an elapsed time requirement is met.

12. An implantable medical device comprising:
a communication subsystem configured to establish a communication link with an external apparatus; and
a controller configured to:
receive a command to initiate real-time monitoring of EEG signals,
establish a communication link with the external apparatus,
initiate real-time monitoring of EEG signals only when a time restriction related to a past request to output the command is met, and
transmit data corresponding to real-time EEG signals from the implantable medical device to the external apparatus through the communication link, when real-time monitoring is initiated.

13. An implantable medical device comprising:
a communication subsystem configured to establish a communication link with an external apparatus; and
a controller configured to:
receive a command to initiate real-time monitoring of EEG signals,
establish a communication link with the external apparatus,
initiate real-time monitoring of EEG signals only when the external apparatus is authenticated and an elapsed time requirement is met, and
transmit data corresponding to real-time EEG signals from the implantable medical device to the external apparatus through the communication link, when real-time monitoring is initiated.

14. The implantable medical device of claim 12 , further comprising a detection subsystem configured to detect a neurological event, wherein the command to initiate real-time monitoring of EEG signals is received by the controller in response to a detection of a neurological event by the detection subsystem.

15. The implantable medical device of claim 13 , further comprising a detection subsystem configured to detect a neurological event, wherein the command to initiate real-time monitoring of EEG signals is received by the controller in response to a detection of a neurological event by the detection subsystem.
