Activa System Components
Implantable Components
 |
Neurostimulators:
A pacemaker-like device that contains a battery and microelectronic circuitry for controlled electrical pulse generation. The neurostimulator is implanted subcutaneously near the clavicle, and generates electrical signals that are delivered by the extension and lead(s) to the targeted structures deep within the brain.
The Kinetra® dual-channel neurostimulator* (shown) accommodates
two extensions/leads, and thus provides bilateral neurostimulation
from a single neurostimulator.
The Kinetra neurostimulator is 61 mm x 76 mm x 13 mm and weighs
83 grams.
The Soletra® neurostimulator accommodates one extension/lead. Two Soletra neurostimulators are required for bilateral therapy. The Soletra neurostimulator is 55 mm x 60 mm x 10 mm and weighs 42 grams. |
 |
DBS™ Lead:
Four thin, insulated, coiled wires bundled within polyurethane insulation. Each wire ends in a 1.5 mm electrode, resulting in four electrodes at the tip of the lead. The DBS Lead delivers stimulation using either one electrode or a combination of electrodes. |
 |
Extension:
An insulated wire that runs subcutaneously along the head, neck, and shoulder to connect the lead to the implanted neurostimulator. |
* The Kinetra Model 7428 Neurostimulator is indicated for Activa Parkinson's Control Therapy only.
