Abstract

Systems and methods provide for the selective prevention of data transfer from a medical device to allow the patient to have privacy when desired. These systems and methods provide medical devices that can be instructed in various ways to stop recording data and/or transmitting data to external devices and systems. These systems and methods also provide external repeater devices that can also be instructed in various ways to stop recording data being received, stop forwarding data that is being or has already been received, and/or to stop soliciting data from the medical device. These systems and methods also provide for a blocking device that may be separate from the medical device and repeater to provide instruction to the medical device and/or repeater to prevent data transfer such as by stopping the recording or transmission of data. Further, the blocking device may be alternatively configured to provide a jamming signal to prevent data transmissions from being successfully communicated between the medical device and the repeater.

Claims

1. A method for inhibiting recording of physiological data sensed by an implantable medical device previously implanted in a patient, the method comprising:

receiving patient input from the patient to begin inhibiting the recording by the implantable medical device, wherein the receiving the input comprises receiving the input at an external communications device; and

upon receiving the input, ceasing to record the data sensed by the implantable medical device, wherein ceasing to record the data comprises sending a communication from the external communications device to the implantable medical device instructing the implantable medical device to stop recording.

2. The method of claim 1, wherein the receiving the input comprises receiving the input at an external blocking device and wherein ceasing to record the data comprises sending a communication from the external blocking device to the implantable medical device instructing the implantable medical device to stop recording.

3. The method of claim 2, comprising generating an indication of inhibited recording, wherein the indication includes a visual indication on the external blocking device.

4. The method of claim 2, comprising generating an indication of inhibited recording, wherein the indication includes an auditory signal transmitted by the external blocking device.

5. The method of claim 1, comprising determining whether a specified period of time has passed and, if so, then no longer ceasing to record data.

6. The method of claim 1, wherein the recorded data comprises physiological patient data.

7. The method of claim 1, wherein the receiving the input=comprises receiving the input at the external communications device and wherein ceasing to record the data comprises stopping recording at the external communications device of the data transmitted from the implantable medical device.

8. The method of claim 1, wherein the receiving the input comprises receiving the input at the implantable medical device through a physiological sensor and wherein ceasing to record data comprises stopping recording of data at the implantable medical device.

9. The method of claim 8, wherein the input comprises a signal at an accelerometer of the implantable medical device.

10. The method of claim 9, wherein the signal received at the accelerometer comprises a series of taps on a patient'"'"'s body.

11. A method for inhibiting communications between an implantable medical device and an external communications device, the method comprising:

receiving at an external blocking device an external input to begin inhibiting the communications between the implantable medical device and the external communications device, the external input configured to instruct the external communications device to cease sending a solicitation for data to the implantable medical device; and

upon receiving the input, ceasing to establish data transmission to the external communications device of the data generated from the implantable medical device by sending a communication from the external blocking device to the external communications device instructing the external communications device to stop recording.

12. An implantable medical device, comprising:

a memory for recording data;

at least one physiological sensor that detects physiological information about a patient to produce data;

a controller configured to;

detect a patient input received at an external communications device and communicated from the external communications device to the implantable medical device, implanted in the patient, to instruct the implantable medical device to stop recording; and

detect the patient input indicating that data recording should cease, and to cease recording data to the memory upon detecting the input.

13. The implantable medical device of claim 12, wherein the at least one physiological sensor comprises an accelerometer, and wherein the input includes a signal from the accelerometer resulting from taps by the patient wearing the implantable medical device.

14. The implantable medical device of claim 12, comprising a timer, and wherein the controller detects from the timer the amount of time that data recording has ceased and restarts data recording upon the expiration of a pre-defined interval.

15. An implantable medical device, comprising:

an implantable communications system that sends and receives signals;

at least one implantable physiological sensor that detects physiological information about a patient to produce data, the at least one implantable physiological sensor comprising an accelerometer; and

an implantable controller configured to detect an input at the at least one implantable physiological sensor indicating that data transmission should cease, and to cease recording data upon detecting the input, wherein the input includes a signal from the accelerometer received through the communications system resulting from taps by a patient wearing the implantable medical device.

16. An external repeater device for communicating with an implantable medical device and a remote external device, the external repeater device comprising:

a communications system that sends and receives signals, the signals comprising patient data received from the implantable medical device;

a memory that stores patient data received from the implantable medical device; and

a controller configured to;

detect a patient input received at the external repeater device and, in response, to direct the communications system to generate a communication to the implantable medical device implanted in the patient, the communication configured to instruct the implantable medical device to stop recording; and

detect the patient input indicating that data recording should cease, and to cease recording to the memory the data received from the implantable medical device upon detecting the input.
