1. An implantable neurostimulator comprising:
- a waveform generator that generates stimulation signals, and delivers the stimulation signals to a targeted tissue of a patient via a plurality of electrodes; and
a waveform controller that controls the waveform generator to generate and deliver at least one of the stimulation signals to the targeted tissue of the patient according to at least one neurostimulation therapy program, and controls the waveform generator to generate and deliver at least one of the stimulation signals to the targeted tissue of the patient according to a patient notification program in response to a low battery condition within the implantable neurostimulator,wherein the at least one of the stimulation signals generated and delivered to the targeted tissue of the patient by the waveform generator according to the patient notification program comprises a patterned stimulation signal that is discernable by the patient.

Abstract
Apparatus and method for independently delivering a plurality of therapy programs in an implantable medical device. A therapy controller configures the device to generate independent pulse trains associated with a plurality of therapy programs and dynamically configures the electrodes to deliver the independent pulse trains to the patient. Once configured, the implantable medical device delivers the plurality of therapy programs to the patient wherein the therapy programs may overlap in time.
