Abstract

A medical system and method of establishing communication between a plurality of implantable medical devices and an external device. An identification command is sent transcutaneously to at least one of the plurality of implantable medical devices. The plurality of implantable medical devices respond to the identification command with an uplink response in one of a plurality of uplink time slots. The external device receives the uplink response from each of at least one of the plurality of implanted medical devices. The external device establishes transcutaneous communication to a selected one of the plurality of implanted medical devices based, at least in part, upon a user selection of one of said plurality of implanted medical devices.

Claims

1. A medical device communication system, comprising:

a plurality of implantable medical devices;

an external device being configured to transcutaneously send an identification command to at least one of said plurality of implantable medical devices;

said plurality of implantable medical devices being configured to respond to said identification command with an uplink response in one of a plurality of uplink time slots;

said external device being configured to receive said uplink response from each of said at least one of said plurality of implanted medical devices;

said external device being configured to establish transcutaneous communication with a selected one of said plurality of implanted medical devices based, at least in part, upon a user selection of one of said plurality of implanted medical devices.

2. A medical device communication system as in claim 1 wherein said external device is configured to develop a list of each of said at least one of said plurality of medical devices responding with said uplink response, to supply said list to said user;

and to establish transcutaneous communication with one of said plurality of implanted medical devices selected from said list by said user.

3. A medical device communication system as in claim 1 wherein said external device is further configured to identify each of said plurality of medical devices based, at least in part, on said uplink signal received;

if at least two of said plurality of medical devices respond with said uplink signal in one of said plurality uplink time slots, to instruct known ones of said plurality of medical devices to cease responding to said identification command; and

to repeat sending said identification command and to repeat receiving said uplink signal.

4. A medical device communication system as in claim 3 wherein said external device is configured to continue to resend identification commands until no two of said plurality of medical devices respond with said uplink signal in one of said plurality of uplink time slots.

5. A medical device communication system as in claim 3 wherein said known ones of said plurality of medical devices cease responding, for a predetermined period of time, to said identification command as a result of being instructed to cease responding.

6. A medical device communication system as in claim 3 wherein said known ones of said plurality of medical devices cease responding, until instructed otherwise, to said identification command as a result of being instructed to cease responding to said identification command.

7. A medical device communication system as in claim 3 wherein said external device is configured to supply a list said plurality of medical devices identified in said identifying step to a user, and to establish transcutaneous communication with one of said plurality of implanted medical devices selected from said list by said user.

8. A medical device communication system as in claim 1 which maintains transcutaneous communication with said selected one of said plurality of medical devices for a remainder of a communication session.

9. A method of selecting one of a plurality of implanted medical devices with which to establish transcutaneous communication from an external device associated with at least one of said plurality of medical devices, comprising the steps of:

sending an identification command from said external device;

at least one of said plurality of implanted medical devices responding to said identification command with an uplink response in one of a plurality of uplink time slots;

receiving said uplink response from each of said at least one of said plurality of implanted medical devices with said external device;

selecting one said plurality of implanted medical devices to establish transcutaneous communication based, at least in part, upon a user selection of one of said plurality of implanted medical devices.

10. A method as in claim 9 wherein said selecting step comprises:

developing a list of each of said at least one of said plurality of medical devices responding with said uplink response;

supplying said list to a user; and

establishing transcutaneous communication with one of said plurality of implanted medical devices selected from said list by said user.

11. A method as in claim 9 further comprising the steps of:

identifying each of said plurality of medical devices based, at least in part, on said uplink signal received;

if at least two of said plurality of medical devices respond with said uplink signal in one of said plurality uplink time slots, instructing known ones of said plurality of medical devices to cease responding to said identification command; and

repeating said sending step, said responding step and said receiving step.

12. A method as in claim 11 wherein said repeating step occurs until no two of said plurality of medical devices respond with said uplink signal in one of said plurality of uplink time slots.

13. A method as in claim 11 wherein said known ones of said plurality of medical devices cease responding to said identification command as a result of instructing step for a predetermined period of time.

14. A method as in claim 11 wherein said known ones of said plurality of medical devices cease responding to said identification command as a result of instructing step until instructed otherwise.

15. A method as in claim 11 wherein said selecting step comprises:

supplying a list said plurality of medical devices identified in said identifying step to a user; and

establishing transcutaneous communication with one of said plurality of implanted medical devices selected from said list by said user.

16. A method as in claim 9 further comprising the step of maintaining transcutaneous communication with said selected one of said plurality of medical devices for a remainder of a communication session.
