1. An implantable stimulation system comprising:
- a neurostimulator having a housing that is sized and shaped to be implanted in the head or neck;
a patient programmer;
a clinician programmer; and
at least one stimulation lead that can be connected to the neurostimulator, the lead having one or more electrode contacts,wherein the neurostimulator is capable of providing a selectable stimulus frequency in at least the range from about 100 Hz to about 4.8 kHz.

Abstract
In accordance with the present invention, various embodiments of neurostimulators and stimulation systems are disclosed that provide different shapes and patterns of stimulus pulses and trains of pulses with fixed and no fixed frequencies. The neurostimulator can be configured to provide high frequency stimulation and also be implantable in the head or neck regions in order to stimulate nerves and nerve ganglions in the head and neck regions and also stimulate the brain.
