Indications for Use

Nexstim Navigated Brain Therapy (NBT®) System 2 is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode.

Device Story

Non-invasive repetitive transcranial magnetic stimulation (rTMS) system; delivers pulsed magnetic fields to induce neural action potentials in prefrontal cortex. Used for Major Depressive Disorder (MDD) treatment. Operated by trained medical professionals in inpatient/outpatient settings (clinics, hospitals). Integrates MRI-based 3D brain modeling with TMS and EMG measurement to localize cortical motor areas and target stimulation sites. Software imports patient MRI slices to generate 3D head models for navigation. System provides Intermittent Theta Burst (iTBS) and 10Hz standard protocols. Output is magnetic stimulation; helps clinicians target therapy precisely to patient anatomy. Benefits patients by providing non-pharmacological treatment for MDD.

Clinical Evidence

Bench testing only. Performance verified via software V&V, electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and usability testing (IEC 62366). Biocompatibility confirmed per ISO 10993-1. No new clinical data provided; substantial equivalence based on technological characteristics and performance testing.

Technological Characteristics

rTMS system; copper winding air-core coil (72mm). Energy source: electrical. Connectivity: standalone/networked. Software: rule-based navigation and stimulation control. Materials: ISO 10993-1 compliant. Standards: IEC 60601-1, IEC 60601-1-2, IEC 62304, IEC 62366.

Indications for Use

Indicated for treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from prior antidepressant medication in the current episode.

Regulatory Classification

Identification

A repetitive transcranial magnetic stimulation system is an external device that delivers transcranial repetitive pulsed magnetic fields of sufficient magnitude to induce neural action potentials in the prefrontal cortex to treat the symptoms of major depressive disorder without inducing seizure in patients who have failed at least one antidepressant medication and are currently not on any antidepressant therapy.

Special Controls
