Intended Use

The Brainsway Deep TMS System is indicated for the treatment of depressive episodes in adult patients suffering from Major Depressive Disorder who failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode.

Device Story

Brainsway Deep TMS System provides non-invasive stimulation of deep brain structures; utilizes electromagnetic coil to deliver brief, high-current magnetic pulses to scalp; induces electric fields in prefrontal cortex to depolarize neurons. System comprises electromagnetic coil, neurostimulator, cooling system, positioning arm, and mobile cart. Used in hospitals/clinics by trained operators. Clinician determines treatment settings (e.g., 120% of motor threshold) and manages patient records via integrated software. Treatment involves repetitive pulse trains to modulate neuronal activity; intended to alleviate symptoms of treatment-resistant MDD. Benefits include non-invasive therapeutic intervention for patients failing medication.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including output waveform, electrical field spatial distribution, magnetic field strength gradient testing, and software validation.

Technological Characteristics

Electromagnetic stimulation system; components include mobile cart, coil/helmet, positioning arm, cooling system, and stimulator. Complies with IEC 60601-1 (electrical/mechanical/thermal safety), IEC 60601-1-2 (EMC), and IEC 62304 (software lifecycle). Biocompatible materials used in head cap. Operates at 110-120 VAC/60Hz or 220-240 VAC/50Hz. Software-controlled parameter configuration.

Indications for Use

Indicated for adult patients with Major Depressive Disorder (MDD) who have failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode.

# Device Description:

The Brainsway Deep TMS System enables direct non-invasive activation of deep brain structures. Transcranial magnetic stimulation (TMS) is a non-invasive technique used to apply brief magnetic pulses to the brain. The pulses are administered by passing high currents through an electromagnetic coil placed adjacent to a patient's scalp. The pulses induce an electric field in the underlying brain tissue. When the induced field is above a certain threshold, and is directed in an appropriate orientation relative the brain's neuronal pathways, localized axonal depolarizations are produced, thus activating neurons in the targeted brain structure.

The FDA cleared Brainsway Deep TMS System is composed of the following main components:

- 1. An Electromagnetic Coil
- 2. A TMS Neurostimulator
- 3. A Cooling System
- 4. A Positioning Device
- 5. A Cart

# Intended Use/Indication for Use:

The Brainsway Deep TMS System is indicated for the treatment of depressive episodes in adult patients suffering from Major Depressive Disorder who failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode ..

# Performance Standards:

Brainsway Deep TMS System complies with the following FDA recognized consensus standards:

- EC 60601-1 Medical Electrical Equipment Part 1: General requirements for . safety 1: collateral standard: safety requirements for medical electrical systems (2005 +A12012)
- IEC 60601-1-2 Medical Electrical Equipment Part 1-2: General requirements for . basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and test (Ed 3 2007)
- . IEC 62304 Medical Devices Software Software life-cycle processes (2006 + A1:2015)

{5}------------------------------------------------

#### Non-Clinical (Bench) Performance Data:

Tests were conducted on the modified Brainsway Deep TMS System. The tests were performed in a similar manner as to the tests performed with the cleared predicate device and according to the FDA Guidance Document Class II Special Controls Guidance Document: Repetitive Transcranial Magnetic Stimulation (rTMS) Systems. These tests included Output Waveform, Electrical Field Spatial Distribution and Magnetic Field Strength Gradient Testing. Additional performance testing included software validation testing in compliance with FDA guidelines for software validation and IEC 62304 standard requirements. The results of the performance tests demonstrated that the Brainsway Deep TMS System is substantially equivalent to the predicate device.

#### Animal Performance Data / Histology Data:

Not Applicable

#### Clinical Performance Data:

Not Applicable

### Substantial Equivalence:

The modified device has the same intended use and indications for use as the cleared Brainsway Deep TMS System. Both the modified device and the cleared Brainsway Deep TMS System are similar in terms of their intended prescription use only, suitable for adult population, indicated for anatomical sites according to indications for use and to be used in hospital or clinic settings.

The basic components of modified Brainsway DTMS System are still similar to the cleared, predicate device and have the same mechanism of operation and use the same underlying technology. The performance characteristics, including the Output Waveform, Electrical Field Spatial Distribution and Magnetic Field Strength Gradient are substantially equivalent to the previously cleared Brainsway DTMS System, as demonstrated in the performance testing.

Using the modified or the cleared Brainsway devices, the user can determine the treatment settings, record patient data, etc. The modified device, as the cleared device, introduces similar safety features and complies with same relevant consensus standards, including software validation. That is, the new stimulator software has been validated to ensure its proper performance.

{6}------------------------------------------------

All device modifications were tested under the design control activities, including inhouse bench testing of the coil and cooling system, software validation in compliance with international standards and FDA guidelines, as well as testing for compliance with relevant consensus standards for electrical and mechanical safety, electromagnetic compatibility and software validation. All potential hazards were mitigated in the performance testing conducted as part of the design control activities. All performance activities show that the modifications made to the cleared device do not pose any new safety and effectiveness concerns. Furthermore, the labeling material was revised to support the above-mentioned modifications.

A comparison of the modified device and the predicate device is presented in the following table:
