| Northstar’s Renova™
Cortical Stimulation System* is designed to treat
neurological disorders by delivering targeted stimulation
to the cerebral cortex. The cerebral cortex is located
on the outer surface of the brain and plays a central
role in many complex brain functions including movement,
behavior, perceptual awareness, language, vision and
hearing.
Stimulation is delivered to the appropriate site
depending on the disorder being treated. Stimulation
is controlled by a clinician and cannot be felt by
the patient. Currently, Northstar is investigating
the safety and efficacy of cortical stimulation for
patients with post-stroke speech and motor deficits,
major depression disorder and tinnitus.

- The Renova-ST™ Cortical Stimulation
System is designed to enhance recovery of stroke
patients who suffer from hemiparesis (weakness or
loss of movement on one side of the body) and Broca’s
aphasia (difficulty speaking). During a stroke,
portions of the brain are damaged. Neural pathways
which may be adjacent to or near the damaged area
will attempt to compensate for the loss of function,
a concept called neuroplasticity. Cortical stimulation
is delivered to this new neuroplastic area, to encourage
and enhance motor function during rehabilitation.
- The Renova-TT™ Cortical Stimulation
System is designed to treat tinnitus. Tinnitus is
the perception of sound in the ears or head where
no external source is present and can be extremely
debilitating. The Renova-TT™ System delivers
targeted stimulation to the auditory cortex, the
portion of the brain’s surface responsible
for perceiving sound.
- The Renova-DT™ Cortical Stimulation
System is designed to treat major depressive disorder.
The Renova-DT™ System delivers targeted
stimulation to the prefrontal cortex, the portion
of the brain’s surface associated with behavior
and emotion.
