Devices and Methods for Delivering Energy as a Function of Condition Severity

A device for regulating energy delivery to an implanted circuit is disclosed. The device may include at least one implantable circuit and at least one pair of implantable electrodes in electrical communication with the circuit. The at least one pair of implantable electrodes may be configured to modulate at least one nerve. The at least one implantable circuit may be configured deliver a signal to the at least one pair of implantable electrodes. The signal may have at least one of a power level or a duration determined based on a severity of a detected physiologic condition.
