Abstract:
1. An implantable medical device (IMD) comprising: stimulation circuitry adapted to provide at least one neural stimulation energy to at least one neural stimulation electrode; one or more timers, including at least one neural event timer, each timer having an output indicating a timer state and an input for changing the timer state; a device behavior memory including a neural table, wherein the neural table maps a particular device state defined at least in part by the neural event timer to one or more associated device actions that include: a state change detector configured to detect a change in a current device state and initiate, in response to the detected change, a search in the neural table for a matching device state; a comparison circuit adapted to compare the current device state to a device state in the neural table and, if found to match, causing performance of one or more associated device actions; and a buffer queue coupled to the device behavior memory, and wherein at least one action input causes an event represented in a current status word to be loaded into the buffer queue along with a time stamp.
