Abstract

A system employing multiple implantable therapy delivery devices may be configured to provide coordinated or synchronized therapy by allowing the devices to communicate with each other, directly or indirectly. Fault tolerance or redundancy may be incorporated into the system to allow for correction of failed devices in real time or pseudo real time.

Claims

1. A method for synchronizing therapy between a first implantable infusion device and a second implantable infusion device, comprising:

providing synchronization operating instructions to at least one of the first and second infusion devices via an external programmer;

providing sensed information to at least one of the first and second infusion devices; and

adjusting a dose of therapeutic agent being delivered, or to be delivered, by at least one of the first and second infusion devices based on the sensed information, wherein the dose adjustment is within parameters defined by the synchronization operating instructions.

2. The method of claim 1, wherein the sensed information is provided to the first infusion device, and wherein the first infusion device provides information regarding the dose adjustment to the second device.

3. The method of claim 1, wherein the sensed information is provided to the first infusion device, and wherein the first infusion device provides data regarding the sensed information to the second infusion device.

4. The method of claim 1, further comprising providing patient input to at least one of the first and second infusion devices.

5. The method of claim 4, wherein the patient input is provided to the first infusion device, and wherein the first infusion device provides the patient input to the second infusion device.

6. The method of claim 4, further comprising adjusting a dose of therapeutic agent being delivered, or to be delivered, by at least one of the first or second infusion devices based on the patient input, wherein the dose adjustment is within parameters defined by the synchronization operating instructions.

7. The method of claim 6, wherein the patient input is provided to the first infusion device, and wherein the first infusion device provides information regarding the dose adjustment to the second device.

8. A method for synchronizing therapy between a first implantable infusion device and a second implantable infusion device, comprising:

providing synchronization operating instructions to at least one of the first and second infusion devices via an external programmer;

providing patient input to at least one of the first and second infusion devices; and

adjusting a dose of therapeutic agent being delivered, or to be delivered, by at least one of the first and second infusion devices based on the patient input, wherein the dose adjustment is within parameters defined by the synchronization operating instructions.

9. The method of claim 8, wherein the patient input is provided to the first infusion device, and wherein the first infusion device provides information regarding the dose adjustment to the second device.

10. The method of claim 8, wherein the patient input is provided to the first infusion device, and wherein the first infusion device sends information regarding the patient input to the second infusion device.

11. A method comprising:

comparing operating parameters of a first infusion device in a multi-infusion device system with operating parameters of a second infusion device of the system to determine whether the first infusion device has failed;

sending operating instructions to the first infusion device from the second device, if a determination is made that the first device has failed, to attempt to correct the failure of the first device.

12. The method of claim 11, further comprising determining whether the first device is operating according to the instructions sent by the second device.

13. The method of claim 12, further comprising operating the first device in safe mode if the first device is not operating according to the instructions sent by the second device.

14. The method of claim 13, wherein the first device is operated in safe mode if a predetermined or preprogrammed number of attempts in a preprogrammed or predetermined duration of time to correct the failure of the first device are made.

15. The method of claim 13, wherein the first device is operated in safe mode if the first device has been determined to have failed a predetermined or preprogrammed number of times in a preprogrammed or predetermined duration of time.

16. The method of claim 12, further comprising adjusting the operating parameters of the second device to compensate for the improper operation of the first device if the first device is not operating according to the instructions sent by the second device.

17. A method for determining whether an implantable therapy delivery device in a multi-device coordinated therapy system is operating in manner not conforming to the system parameters, comprising:

determining what a first, second and third implantable devices of the system consider to be the system parameters; and

determining whether a conflict exists between what the first, second and third implantable devices consider to be the system parameters,

wherein if a conflict exists, the system parameters are set as the system parameters of the two non-conflicting devices if they exist.

18. A method comprising:

comparing operating parameters of a first implanted therapy delivery device in a multi-device system with operating parameters of a second implanted therapy delivery device of the system to determine whether the first therapy delivery device has failed;

sending operating instructions to the first therapy delivery device from the second therapy delivery device if a determination is made that the first device has failed.

19. The method of claim 18, wherein comparing the operating parameters of the first and second device comprises comparing operating parameters of the first device that are redundantly stored on the second device with operating parameters of the first device that are stored on the first device.
