A medical device system includes at least one controllable patient-worn or patient-carried medical device, and a plurality of controller devices that are capable of independently controlling features or functions of the patient medical device. Control commands and other data is wirelessly communicated among the patient medical device and the multiple controller devices. A number of techniques, protocols, and other measures are provided to coordinate wireless communication between the various devices in a medical device system. These control command coordination processes address situations where conflicting, redundant, or concurrent control commands might be independently issued by the multiple controller devices.

1. A method of coordinating control commands in a medical device system comprising a medical device for a patient, and a plurality of wireless controller devices for the medical device, each of the wireless controller devices being capable of independently issuing control commands for the medical device, the method comprising: wirelessly broadcasting a lockout message from a first controller device of the plurality of wireless controller devices, the lockout message being formatted to disable at least one function of a second controller device of the plurality of wireless controller devices upon receipt of the lockout message at the second controller device;thereafter, wirelessly transmitting a control command from the first controller device, the control command being formatted to control a function of the medical device upon receipt of the control command by the medical device; andthereafter, wirelessly broadcasting an unlock message from the first controller device, the unlock message being formatted to clear the lockout message at the second controller device upon receipt of the unlock message at the second controller device. 2. The method of claim 1, wherein the lockout message is formatted to disable all functions of the second controller device. 3. The method of claim 1, wherein: the medical device is configured to deliver therapy to the patient; andthe lockout message is formatted to selectively disable functions of the second controller that control delivery of therapy to the patient. 4. The method of claim 1, wherein: the medical device is configured to deliver therapy to the patient; andthe lockout message is formatted to selectively disable functions of the second controller device that affect delivery of therapy to the patient. 5. The method of claim 1, further comprising: maintaining the first controller device in an idle state when the first controller device is inactive; anddetecting user interaction with the first controller device while the first controller device is in the idle state, wherein the lockout message is wirelessly broadcast in response to the user interaction. 6. The method of claim 1, further comprising wirelessly receiving an acknowledgment message at the first controller device, wherein: the acknowledgement message indicates that the control command was executed by the medical device; andthe unlock message is wirelessly broadcast in response to the acknowledgement message. 7. The method of claim 1, wherein the lockout message is formatted to disable at least one function of the medical device upon receipt of the lockout message by the medical device. 8. The method of claim 1, further comprising synchronizing, in response to the unlock message, status information of the second controller device with status information of the first controller device. 9. The method of claim 8, wherein the unlock message comprises synchronization data that facilitates the synchronizing of the status information. 10. The method of claim 1, wherein the medical device system comprises an insulin infusion system, and the medical device comprises a portable insulin infusion pump that is worn or carried by the patient. 11. The method of claim 1, further comprising disabling at least one function of the first controller device when the first controller device loses wireless connectivity with the medical device. 12. A method of coordinating control commands in a medical device system comprising a medical device for a patient, and a plurality of wireless controller devices for the medical device, each of the wireless controller devices being capable of independently issuing control commands for the medical device, the method comprising: wirelessly receiving a lockout message at a first controller device of the plurality of wireless controller devices, wherein the lockout message is broadcast by a second controller device of the plurality of wireless controller devices in preparation of issuing a control command for the medical device;disabling at least one function of the first controller device upon receipt of the lockout message at the first controller device, resulting in at least one disabled function;thereafter, wirelessly receiving an unlock message at the first controller device; andenabling the at least one disabled function upon receipt of the unlock message at the first controller device. 13. The method of claim 12, wherein the disabling step disables all functions of the first controller device. 14. The method of claim 12, wherein: the medical device is configured to deliver therapy to the patient; andthe disabling step selectively disables functions of the first controller device that control delivery of therapy to the patient. 15. The method of claim 12, wherein: the medical device is configured to deliver therapy to the patient; andthe disabling step selectively disables functions of the first controller device that affect delivery of therapy to the patient. 16. The method of claim 12, further comprising synchronizing, in response to the unlock message, status information of the first controller device with status information of the second controller device. 17. The method of claim 16, wherein the unlock message comprises synchronization data that facilitates the synchronizing of the status information. 18. The method of claim 12, wherein the unlock message is wirelessly received from the second controller device. 19. The method of claim 12, wherein the unlock message is wirelessly received from the medical device. 20. The method of claim 12, wherein the medical device system comprises an insulin infusion system, and the medical device comprises a portable insulin infusion pump that is worn or carried by the patient. 21. The method of claim 12, further comprising disabling at least one function of the first controller device when the first controller device loses wireless connectivity with the medical device.
