The summary describes a standard TMS device and does not mention any AI or ML components or functionalities.
Yes
The device is indicated for the treatment of Major Depressive Disorder in adult patients and applies magnetic fields to induce electrical currents for therapeutic effect on the cerebral cortex.
No
Explanation: The device is indicated for "treatment of Major Depressive Disorder," and its description focuses on stimulating brain tissue to induce electrical currents for therapeutic purposes, rather than for diagnosis.
No
The device description explicitly states it is a "computerized, electromechanical medical device" and lists several hardware components (Stimulator, Coil, Marking apparatus, Patient head fixation, Isolation Transformer) that are integral to its function of producing and delivering magnetic fields.
Based on the provided text, the Mag Vita TMS Therapy System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Definition of IVD: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Description: The Mag Vita TMS Therapy System is described as a device that produces and delivers magnetic fields to induce electrical currents in the brain. It directly interacts with the patient's body (non-invasive stimulation of the cerebral cortex).
- Intended Use: The intended use is for the treatment of Major Depressive Disorder by stimulating the brain, not for analyzing biological specimens.
The device operates by applying physical stimulation to the brain, which is a direct therapeutic intervention, not a diagnostic test performed on a sample outside the body.

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 as effective as the predicate device 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 MagVita TMS therapy system is applied to the human brain on the left dorsolateral prefrontal cortex (DLPFC).
The MagVita TMS Therapy System is an integrated system consisting of the following components:
- MagPro Stimulator and Trolley
- MagPro family
- Trolley with holding arrangements
- Coil for MT determination
- Coil C-B60
- Marking apparatus for locating treatment area
- Marking plate for Coil C-B60
- Pen for marking, Cap, Ruler
- Patient head fixation
- Treatment Chair
- Vacuum Pump and Vacuum pillow
- Super Flexible Arm mounted on the trolley
- Coil for Depression Treatment
- Coil Cool-B65 with Coil Cooler unit

Substantial equivalence:
The MagVita TMS Therapy System is substantially equivalent to the predicate device (Neurostar TMS Therapy® System). The MagVita TMS Therapy System and the predicate device have identical intended use /indication for use, and the technological characteristics are very similar such that they in our view can be considered equivalent.
The MagVita TMS Therapy System 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 System is similar to the predicate device as both 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 System 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 essentially the same.

Conclusion:
The above comparison, demonstrates and supports the substantial equivalency of the MagVita TMS Therapy System to the NeuroStar TMS Therapy System
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 MagVita TMS Therapy System and the predicate device NeuroStar TMS Therapy System.
The transducer design (figure-of-eight) are equivalent and the realized magnetic properties of the MagVita TMS Therapy System and the predicate device are substantial equivalent for the two coils.
The reliability of the positioning method used by the MagVita TMS Therapy System is, based on the direct relationship of the underlying cortical brain anatomy to the patient's scalp, as is the method used in the predicate device. The method for identifying the correct treatment position in the Mag Vita TMS Therapy System is at least as effective as the method employed by the predicate device.
The MagVita TMS Therapy System does not introduce any new safety considerations in comparison to the predicate device.
All other identified differences between the two systems are minor and without any known impact on safety or efficacy.
