Claim:
A method of preventing inadvertent signal transmission from a remote control to an implantable infusion device, the remote control including a signal generation button, the method comprising the steps of: maintaining the remote control in a locked state where pressing the signal generation button or a structure over the signal generation button will not result in transmission of a medication delivery signal to the implantable infusion device; unlocking the remote control in response to a user action that demonstrates an intent to transmit a signal; and wirelessly transmitting a medication delivery signal to the implantable infusion device in response to a pressing of the signal generation button while the remote control is unlocked; wherein the user action that demonstrates an intend to transmit a signal is selected from the group consisting of (a) moving a button control element from a position that prevents the signal generation button from being pressed to a position that does not prevent the signal generation button from being pressed, (b) unlocking a button lock, (c) pressing a button other than the signal generation button, (d) pressing the signal generation button in a predetermined sequence, and (e) shaking the remote control; and wherein the user action is not turning the remote control on with an on/off button; and wherein the user action is not turning the remote control on with an on/off switch.
