The device description and performance studies focus on hardware, power electronics, user interface, and basic stimulation parameters, with no mention of AI/ML algorithms or data processing for decision-making or analysis.
No.
The device is intended for diagnostic purposes (stimulation of peripheral nerves for diagnostic purposes), not for therapeutic treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "intended for stimulation of peripheral nerves for diagnostic purposes."
No
The device description explicitly states that the STM 9000 consists of "power electronics to generate the magnetic field in the magnetic coil" and is "connected to a magnetic coil," indicating the presence of hardware components beyond just software.
Based on the provided information, the STM9000 is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is "stimulation of peripheral nerves for diagnostic purposes." This involves interacting directly with the patient's body (in vivo) to elicit a response for diagnosis.
- Device Description: The device description confirms it's a magnetic stimulator used to stimulate neural and cortical tissue. This is an external, non-invasive procedure performed on a living subject.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, outside of the body (in vitro) to detect diseases, conditions, or infections.
The STM9000 operates by applying a stimulus to the patient's body, not by analyzing samples taken from the body. Therefore, it falls outside the definition of an IVD.

Device Description
The STM 9000 are magnetic stimulators used for magnetic stimulation. Magnetic stimulation is a noninvasive technique for stimulating neural and cortical tissue. Application areas of magnetic stimulation are a subset of the application areas for current stimulation.
The STM 9000 is connected to a magnetic coil which transfers the magnetic stimulation to the tissue. The following coils can be used with the STM 9000 family of magnetic stimulators:
Code Description
B9621086002 Circular Coil 90 mm
B9621086001 Circular Coil 70 mm
B9621086003 Butterfly Coil 70 mm
B9621086004 Butterfly Coil 70 mm air cooled
B9621086005 Butterfly Coil 80 mm, 120°
B9621086006 Circular Coil 90 mm air cooled
The STM 9000 consists of power electronics to generate the magnetic field in the magnetic coil. The STM 9000 is controlled via a simple user interface, enabling the operator to overview all functions, stimulus sequences, controls, status and measured data. The magnetic pulse is capable of biphasic and monophasic waveforms and the stimulate with a frequency up to 100 pulses per second (pps).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Biocompatibility Testing: The biocompatibility evaluation for the STM9000 was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing," May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests: Cytotoxicity, Sensitization, Irritation. The STM9000 coils are considered a surface device contacting intact skin for a duration of less than 24 hours.
Electrical Safety and Electromagnetic Compatibility (EMC): Electrical safety and EMC testing were conducted on the STM9000. The system complies with the IEC 60601-1, IEC 60601-1-4 standards for safety and the IEC 60601-1-2 standard for EMC.
Software Verification and Validation Testing: Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "Moderate" level of concern, since a failure or latent flaw in the software could directly result in minor injury to the patient or operator.

IV. Device Description
The STM 9000 are magnetic stimulators used for magnetic stimulation. Magnetic stimulation is a noninvasive technique for stimulating neural and cortical tissue. Application areas of magnetic stimulation are a subset of the application areas for current stimulation.
The STM 9000 is connected to a magnetic coil which transfers the magnetic stimulation to the tissue. The following coils can be used with the STM 9000 family of magnetic stimulators:
| Code | Description |
|---|---|
| B9621086002 | Circular Coil 90 mm |
| B9621086001 | Circular Coil 70 mm |
| B9621086003 | Butterfly Coil 70 mm |

|---|---|
| B9621086005 | Butterfly Coil 80 mm, 120° |
| B9621086006 | Circular Coil 90 mm air cooled |
The STM 9000 consists of power electronics to generate the magnetic field in the magnetic coil. The STM 9000 is controlled via a simple user interface, enabling the operator to overview all functions, stimulus sequences, controls, status and measured data. The magnetic pulse is capable of biphasic and monophasic waveforms and the stimulate with a frequency up to 100 pulses per second (pps).
V. Intended Use
The STM9000 is intended for stimulation of peripheral nerves for diagnostic purposes.
VI. Comparison of Technological Characteristics
The technological characteristics of STM9000 are similar to those of MagPro X100. The devices are magnetic stimulators used for magnetic stimulation as a non-invasive technique for stimulating neural tissue. All devices are capable of single stimulation mode and repetitive stimulation mode.
The subject and predicate devices are connected to magnetic coils which transfer the magnetic stimulation to the tissue. The operator controls the functions and status of the devices through an interface consisting of a graphic LCD, a keyboard and a multifunction knob, integrated in the stimulator. The mechanical, electrical, and magnetic parameters of the coils in this submission are very near to the parameters of the predicate coils.
The main differences between the subject device and predicate are:
- -In some configurations, the STM9000 has a lower maximum repetition rate and/or allowable energy level than the predicate configurations
