What components make up the Activa® System?
A. The Activa® System consists of three implantable components: • DBS™ lead – A thin, insulated wire lead (pronounced LEED) with four electrodes at the tip. Using standard clinical imaging techniques and stereotactic equipment, the neurosurgeon positions the electrodes of the lead in the brain’s thalamus, and the lead is anchored to the skull. • Neurostimulator – The extentsion is connected to a neurostimulator, a small, sealed device simulator to a cardiac pacemaker that contains a battery and electronics. The neurostimualator is implanted beneath the skin in the chest. It produces the electrical pulses needed for stimulation. These electrical pulses are delivered through the extension and through the lead to the globus pallidus or subthalamic nucleus in the brain • Extension – An insulated wire that is surgically passed under the skin of the head, neck, and shoulder to connect the lead to the implanted neurostimulator.
