Abstract

This document discusses, among other things, methods and systems for facilitating automated device programming at changeout. A method comprises receiving, from a first device, physiological data at a temporary storage device; and processing the received physiological data, wherein the processing includes determining if a first signal processing function was used by the first device and substantially offsetting the first signal processing function if the first signal processing function was used by the first device; and processing the resultant physiological data to be compatible with a second device. The method further comprising providing the processed resultant physiological data to the second device.

Claims

1. A system comprising:

an external processing device, comprising;

a communications port, adapted to receive physiological data from a first medical device, wherein the physiological data was obtained from raw data by the first medical device using a first signal processing function;

a processor, to process the received physiological data by applying a second signal processing function to the received physiological data, wherein the second signal processing function substantially reverses the first signal processing function to provide reverted data, wherein the reverted data is approximate to the raw data; and

a memory, to store the received physiological data and the reverted data;

wherein the communications port is adapted to transmit the reverted data to a second medical device.

2. The system of claim 1, wherein the second medical device is adapted to apply a third signal processing function to convert the received reverted data to be compatible with the second medical device.

3. The system of claim 2, wherein the communications port is adapted to be connected to an external programmer for an implantable medical device, and wherein at least one of the first and second medical devices are implantable medical devices.

4. The system of claim 2, wherein the external processing device includes an external programmer for an implantable medical device, and wherein at least one of the first and second medical devices are implantable medical devices.

5. The system of claim 2, wherein the communications port is adapted to be connected to an external programmer for an ambulatory medical device, and wherein at least one of the first and second medical devices are ambulatory medical devices.

6. The system of claim 2, wherein the external processing device includes an external programmer for an ambulatory medical device, and wherein at least one of the first and second medical devices are ambulatory medical devices.

7. The system of claim 2, wherein the external processing device includes a remote computing device, communicatively coupled to the first and second medical devices.

8. The system of claim 1, wherein the external processing device is a handheld device, and wherein the memory comprises nonvolatile memory.

9. The system of claim 1, wherein the communications port includes a USB connector.

10. The system of claim 1, wherein the physiological data includes electrocardiogram data.

11. The system of claim 1, wherein the physiological data is associated with a tachyarrhythmia episode.

12. The system of claim 1, wherein the second signal processing function is calculated to minimize at least one of a mean squared error, a minimum phase shift, a minimum dominant frequency component deterioration, a reserved signal-to-noise ratio, or a high cross-correlation between sensed physiological data and the resultant physiological data.

13. The system of claim 1, wherein at least one of the first and second signal processing functions include at least one of a frequency-selective function, an upsampling function, a downsampling function, a re-sampling function, a filtering function, an amplifying function, an attenuating function, an averaging function, a function to calculate the median, mode, standard deviation or quartiles, a function to build a histogram, a function to estimate a probability distribution function or cumulative distribution function, or a compressing function.

14. The system of claim 1, wherein processor is adapted to apply the second signal processing function in a time domain.

15. The system of claim 1, wherein processor is adapted to apply the second signal processing function in a frequency domain.

16. The system of claim 1, wherein the second signal processing function comprises a plurality of signal processing functions aggregated to substantially reverse the effects of the first signal processing function on the raw data.

17. The system of claim 1, wherein the communications port is adapted to receive device settings associated with the first medical device, and wherein the processor is adapted to configure the device settings to be compatible with the second medical device.

18. The system of claim 17, wherein the communications port is adapted to transmit the configured device settings to the second medical device.

19. The system of claim 18, wherein the device settings include at least one of a tachy rate zone, a brady pacing mode, one or more thresholds of tachy discrimination algorithms, a tachy therapy parameter, a morphological template, a brady therapy parameter, one or more thresholds of heart failure decompensation detection algorithms, one or more thresholds of apnea detection algorithms, a patient name, a patient gender, a patient birth date, a patient height, a patient weight, a patient New York Heart Association class, a patient left ventricular ejection fraction, or a physician contact information.

20. A system comprising:

an external processing device, comprising;

a communications port, adapted to receive physiological data from a first implantable medical device, wherein the physiological data was obtained from raw data by the first implantable medical device using a first signal processing function;

a processor, to process the received physiological data by applying a second signal processing function to the received physiological data, wherein the second signal processing function substantially reverses the first signal processing function to provide reverted data, wherein the reverted data is approximate to the raw data; and

a memory, to store the received physiological data and the reverted data;

wherein the communications port is adapted to transmit the reverted data to a second implantable medical device that is adapted to apply a third signal processing function to convert the received reverted data to be compatible with the second implantable medical device.
