## Device description

The MagVita TMS Therapy System is a computerized, electromechanical medical device that produces and delivers non-invasive, magnetic fields to induce electrical currents directed at regions of the cerebral cortex. The Mag Vita TMS Therapy System is indicated for

### Treatment of Major Depressive Disorder in adult patients who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.

Transcranial magnetic stimulation (TMS) is a non-invasive technique for stimulating brain and neural tissue. The principle of magnetic stimulation is implicit in Faraday's law. The pulses of current are generated with a circuit containing a capacitor connected to the stimulating coil. With the capacitor charged to a certain level, the conducting state will cause the discharging of the capacitor through the coil. A magnetic field is generated proportional to this current. The rapid change in the magnetic field induces a current in conducting materials e.g. the body tissue. If the current induced in the human body is of sufficient amplitude and duration, it will excite neurons.

In the MagVita TMS therapy system TMS pulses are applied repetitively at a frequency of 10Hz. Such stimulation has been shown to be effective in modulating cortical excitability. The observed and documented increase in cortical excitability after high frequency (10Hz) repetitive transcranial magnetic stimulation has been shown to persist beyond the duration of the train of stimulation. Repetitive Magnetic stimulation with the Mag Vita TMS therapy system is applied to the human brain on the left dorsolateral prefrontal cortex (DLPFC).

The MagVita TMS Therapy w/MagPro R20 is an integrated system consisting of the following components:

- MagPro Stimulator and Trolley .
- MagPro R20 o
- Trolley with holding arrangements o
- Coils for MT determination and Depression Treatment .
- Coil MCF-B70 o
- . Marking apparatus for locating treatment area
- Marking plate for Coil MCF-B70 o
- Pen for marking, Cap, Ruler o
- Patient head fixation .
- Treatment Chair o
- Vacuum Pump and Vacuum pillow o
- Super Flexible Arm mounted on the trolley o
- Isolation Transformer .

### The Modification

The difference between the cleared MagVita TMS Therapy w/MagPro R20 and the modified MagVita TMS Therapy w/MagPro R20 (this submission) is the replacement of the two MCF-B65 coils with one MCF-B70 coil.

## Intended Use/Indication for Use:

Treatment of Major Depressive Disorder in adult patients who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.

#### Standards:

The MagVita TMS Therapy System w/MagPro R20 has been tested and complies with the following standards

- ISO 13485:2012 .
- IEC60601-1 .
- IEC60601-1-2 .

#### Non-Clinical performance data:

The non-clinical performance testing of the components of the Mag Vita TMS Therapy System has been tested as required, and cleared by the FDA earlier on K170114.

These tests demonstrate that the MagVita TMS Therapy System is safe and effective for use in treatment of Major Depressive Disorder.

#### Substantial equivalence:

The MagVita TMS Therapy w/MagPro R20 is substantially equivalent to the predicate device (our own MagVita TMS Therapy w/MagPro R20 before the modification). The MagVita TMS Therapy w/MagPro R20 and the predicate device have identical intended use /indication for use, and the technological characteristics are similar such that they in our view can be considered equivalent.

The MagVita TMS Therapy w/MagPro R20 and the predicate device are both indicated for

### Treatment of Major Depressive Disorder in adult patients who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.

Design of the MagVita TMS Therapy w/MagPro R20 is similar to the predicate device as all systems apply Transcranial Magnetic Stimulation as repetitive pulse trains at 10Hz delivered as brief rapidly alternating magnetic fields to induce electrical currents over the prefrontal cortex.

Both the MagVita TMS Therapy and the predicate device have the same components consisting of TMS stimulator with software, electromagnetic coil and an articulated arm for positioning of the treatment coil. The operational procedures including system setup, patient preparations, motor threshold determination, coil positioning and treatment with predefined treatment stimulation parameters are identical.

# Characteristics of the Device as Compared to Predicate Device

{7}------------------------------------------------

## Conclusion:

The SE comparison as documented in the Substantial Equivalence section together with the Appendix 1 regarding the coil properties demonstrates and supports the substantial equivalency of the modified MagVita TMS Therapy w/MagPro R20 to our own notmodified MagVita TMS Therapy w/MagPro R20.

The indication for use, the target population, the dosage, the treatment procedure, the treatment position and all relevant protocol parameters (intensity, repetition rate, number of pulses in a train, numbers of trains, number of treatment sessions) are identical for the modified MagVita TMS Therapy w/MagPro R20 and the predicate device.

The transducer design (figure-of-eight) is equivalent and the realized magnetic properties of the MagVita TMS Therapy System and the predicate device are substantial equivalent for the treatment coils.

The MagVita TMS Therapy w/MagPro R20 does not introduce any new safety considerations in comparison to the predicate device.
