Activa SC Neurostimulator

Deep Brain Stimulation

Overview

The Activa SC neurostimulator is a single-channel device with a daily maintenance-free battery that provides predictable longevity. Two Activa SC neurostimulators are required for bilateral therapy. Activa SC contains a nonrechargeable battery and microelectronic circuitry to deliver a controlled electrical pulse to a precisely targeted area of the brain. The device is typically implanted subcutaneously near the clavicle, connected to an extension, and a lead implanted in the brain.

The Activa Portfolio provides the unprecedented ability to control the stimulation field with innovative interleaved pulses and patient-specific therapy groups.


INDICATIONS

MEDTRONIC DBS THERAPY FOR PARKINSON'S DISEASE

Bilateral stimulation of the internal globus pallidus (GPi) or the subthalamic nucleus (STN) using Medtronic DBS Therapy for Parkinson's Disease is indicated for adjunctive therapy in reducing some of the symptoms in individuals with levodopa-responsive Parkinson's disease of at least 4 years' duration that are not adequately controlled with medication, including motor complications of recent onset (from 4 months to 3 years) or motor complications of longer-standing duration.

MEDTRONIC DBS THERAPY FOR TREMOR

Unilateral thalamic stimulation of the ventral intermediate nucleus of the thalamus (VIM) using Medtronic DBS Therapy for Tremor is indicated for the suppression of tremor in the upper extremity. The system is intended for use in patients who are diagnosed with Essential Tremor or Parkinsonian tremor not adequately controlled by medications and where the tremor constitutes a significant functional disability. The safety or effectiveness of this therapy has not been established for bilateral stimulation.

MEDTRONIC DBS THERAPY FOR DYSTONIA*

Medtronic DBS Therapy for Dystonia is indicated for unilateral or bilateral stimulation of the internal globus pallidus (GPi) or the subthalamic nucleus (STN) to aid in the management of chronic, intractable (drug refractory) primary dystonia, including generalized and/or segmental dystonia, hemidystonia, and cervical dystonia (torticollis), in patients 7 years of age or above.

Medtronic Reclaim DBS Therapy FOR OBSESSIVE-COMPULSIVE DISORDER*

The Medtronic Reclaim DBS Therapy is indicated for bilateral stimulation of the anterior limb of the internal capsule, AIC, as an adjunct to medications and as an alternative to anterior capsulotomy for treatment of chronic, severe, treatment-resistant obsessive-compulsive disorder (OCD) in adult patients who have failed at least three selective serotonin reuptake inhibitors (SSRIs).


PRODUCT DETAILS

MR CONDITIONAL

Medtronic gives you the first safe access to MRI anywhere on the body for diagnosing health conditions in DBS patients. Eligible patients with an Activa SC neurostimulator may have an MRI scan anywhere on the body under certain conditions. Refer to the MRI Guidelines for Medtronic Deep Brain Stimulation Systems and DBS MRI Eligibility Sheet for a complete list of conditions and instructions for use (available on the Medtronic Manual Library).

Activa SC Model 37602 is not eligible for full-body MRI.

BATTERY PREDICTABILITY

Medtronic Activa neurostimulators ensure predictable battery life, and typically give warning more than 3 months before replacement is needed. Patients with unusually high settings may receive their notification when less battery life remains.

ADVANCED PROGRAMMING

  • Establish programming groups that may allow patients to reach optimized settings sooner.
  • Achieve finer control over the stimulation field by delivering multiple programs per lead.

DEVICE STORAGE

Patient-specific data — including historical settings and therapeutic response — is stored in the neurostimulator for easy access from the N'Vision programmer.
