Abstract

A method according to an aspect of the present invention includes receiving data from a plurality of medical devices through a wired connection, transmitting the data to an intermediary device, and formatting a message including the received data for transmission to a medical data server. This method can be practiced automatically to allow a medical device for a patient or other subject to be monitored without requiring the patient to manually enter information. This method also allows any number of different medical devices to be monitored, even where such devices each communicate using different wired connections and/or using different communication protocols.

7. The method of claim 1, wherein the data is transmitted to the intermediary device using a wired connection.

8. The method of claim 1, wherein the data includes respective information regarding a plurality of patients associated with one or more of the plurality of medical devices.

9. The method of claim 8, wherein the respective information regarding the plurality of patients associated with the one or more of the plurality of medical devices includes a patient identifier for each of the respective plurality of patients.

10. The method of claim 1, wherein the data includes diagnostic information regarding one or more of the plurality of medical devices.

11. The method of claim 1, wherein the data includes an environmental parameter, wherein the environmental parameter includes at least one of a battery charge level, a temperature, a barometric pressure, a code relating to an accessory for one or more of the plurality of medical devices, a data validity measurement, an elapsed time since a previous reading by one or more of the plurality of medical devices, a test result parameter, a signal-to -noise parameter, and a quality of service (QoS) parameter.

12. The method of claim 1, wherein the data is received from the plurality of medical devices through a connection selected from the group consisting of an optical fiber connection, a tip and sleeve (TS) connection, a tip, ring, and sleeve (TRS) connection, a tip, ring, ring, and sleeve (TRRS) connection, a serial peripheral interface bus (SPI) connection, a universal serial bus (USB) connection, an RS-232 serial connection, an Ethernet connection, a FireWire connection, and combinations thereof.

13. The method of claim 1, wherein one or more of the plurality of medical devices is at least partially implanted in a patient.

14. The method of claim 1, wherein one or more of the plurality of medical devices is coupled to the patient via a plurality of electrodes.

15. The method of claim 1, further including displaying a list of devices whose data has been received.

16. The method of claim 15, further comprising selecting, through a user interface, a subset of the displayed list of devices wherein the respective received data for the subset is transmitted to the intermediary device.
