The device is also approved for dystonia in Europe.

The Activa SC system is comprised of an implantable neurostimulator; a thin, insulated lead that is placed in a specific target within the brain; and an extension to connect the neurostimulator and the lead.

Like Activa PC, Activa SC is powered by a primary cell (non-rechargeable) battery that does not require maintenance from the patient to provide continuous stimulation for multiple years.

An external physician programmer is used to non-invasively adjust stimulation programming parameters, and a hand-held patient programmer with an LCD screen is used by the patient to modify pre-set stimulation settings or check the battery status.

Activa SC, like all Medtronic DBS devices, is approved for MRI scans under specified conditions.
