Abstract

A multiprogrammer system, for monitoring and optimizing implant performance, includes at least two programmers and an implant. Each programmer may perform inquiry and programming operations on the implant. In an inquiry operation, the programmer retrieves some or all of the configuration parameters from the implant. In a programming operation, the programmer provides one or more modified parameters to the implant. As part of the programming operation, the programmer is configured to verify that it is aware of the implant'"'"'s current parameters before sending modified parameters. The current programmer verifies that the implant'"'"'s parameters have not been altered since the current programmer'"'"'s last interaction with the implant. If the parameters have been altered, the current programmer aborts the programming operation and provides notification. The verification may be performed by the implant, i.e., it may verify that the programmer is aware of the current device parameters before the implant accepts modified parameters.

Claims

1. A method, comprising:

programming parameters in a medical implant;

determining if the parameters have been altered since the programming parameters;

modifying the parameters if the parameters have not been altered; and

not modifying the parameters if the parameters have been altered, wherein said determining includes verifying the parameters are current parameters from a comparison of verification data with programmed parameters.

2. The method of claim 1, wherein said programming parameters includes programming the parameters with a programmer, and wherein said halting said modifying the parameters includes notifying an operator that the programmer was not a last device to interact with the medical implant.

3. The method of claim 1, wherein said programming parameters includes programming the parameters with a first programmer and subsequently altering the parameters with a second programmer.

4. The method of claim 3, wherein said modifying the parameters includes modifying the parameters with the second programmer.

5. The method of claim 3, wherein said halting said modifying the parameters includes halting said modifying the parameters when modification is attempted using the first programmer.

6. The method of claim 1, wherein said programming parameters in a medical implant includes storing a program in the medical implant and storing configuration parameters in the medical implant, the stored configuration parameters being capable of controlling operation of the program.

7. The method of claim 1, wherein said halting includes electronically transferring verification data between the medical implant and a programming device.

8. The method of claim 1, wherein said verifying parameters includes verifying configuration parameters that control a therapy provided by an implantable cardioverter/defibrillator are current.

9. A method, comprising:

programming parameters in a medical implant;

determining if the parameters have been altered since the programming parameters;

modifying the parameters if the parameters have not been altered; and

not modifying the parameters if the parameters have been altered, wherein said halting said modifying the parameters includes notifying an operator that the programmer was not a last device to interact with the medical implant.

10. The method of claim 9, wherein said programming parameters in a medical implant includes storing a program in the medical implant and storing configuration parameters in the medical implant, the stored configuration parameters being capable of controlling operation of the program.

11. The method of claim 9, wherein said halting includes electronically transferring verification data between the medical implant and a programming device.

12. The method of claim 9, wherein said determining includes verifying the parameters are current parameters from a comparison of verification data with programmed parameters.

13. The method of claim 12, wherein said verifying parameters includes verifying configuration parameters that control a therapy provided by an implantable cardioverter/defibrillator are current.

14. A method, comprising:

programming parameters in a medical implant, wherein said programming parameters includes programming the parameters with a first programmer and subsequently altering the parameters with a second programmer;

determining if the parameters have been altered since the programming parameters;

modifying the parameters if the parameters have not been altered, wherein said modifying the parameters includes modifying the parameters with the second programmer; and

not modifying the parameters if the parameters have been altered, wherein said halting said modifying the parameters includes notifying an operator that the first programmer was not a last device to interact with the medical implant, and wherein said halting said modifying the parameters includes halting modifying the parameters when modification is attempted using the first programmer.

15. The method of claim 14, wherein said programming parameters in a medical implant includes storing a program in the medical implant and storing configuration parameters in the medical implant, the stored configuration parameters being capable of controlling operation of the program.

16. The method of claim 15, wherein said halting includes electronically transferring verification data between the medical implant and a programming device.

17. The method of claim 15, wherein said determining includes verifying the parameters are current parameters from a comparison of verification data with programmed parameters.

18. The method of claim 17, wherein said verifying parameters includes verifying configuration parameters that control a therapy provided by an implantable cardioverter/defibrillator are current.
