More Information

Not Found

No
The summary describes a standard Transcranial Magnetic Stimulation (TMS) system and does not mention any AI or ML components in its description, intended use, or performance testing.

Yes
The device is indicated for the "treatment of Major Depressive Disorder" and is described as a "non-invasive tool for the stimulation of cortical neurons for the treatment of Major Depressive Disorder."

No

Explanation: The device is described as a "Therapy System" indicated for "treatment of Major Depressive Disorder." Its function is to "produce and deliver non-invasive, magnetic stimulation" for "cortical stimulation." These descriptions clearly indicate a therapeutic, rather than diagnostic, function.

No

The device description explicitly states that the HORIZON™ Therapy System is an integrated system consisting of a combination of hardware, software, and accessories, and it is a computerized, electromechanical medical device.

Based on the provided information, the HORIZON™ Therapy System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is for the treatment of Major Depressive Disorder by applying magnetic stimulation to the brain. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
  • Device Description: The description clearly states it's a "computerized, electromechanical medical device that produces and delivers non-invasive, magnetic stimulation." This describes a physical device used for treatment, not a reagent, instrument, or system intended for use in the diagnosis of disease or other conditions.
  • Lack of IVD Characteristics: The description does not mention any components or processes typically associated with IVDs, such as analyzing biological samples (blood, urine, tissue, etc.), using reagents, or providing diagnostic information based on laboratory testing.

Therefore, the HORIZON™ Therapy System falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Electrical safety and electromagnetic compatibility ("EMC") testing was conducted on the system to demonstrate that the device is compliant with IEC 60601-1 (Ed. 3.1.) and IEC 60601-1-2 (2007). Environmental testing also demonstrated compliance with IEC 60601-1. The biocompatibility evaluation demonstrated that both coils meet ISO 10993-1 (2009) standards. In addition, acoustic output measurements have been conducted during IEC 60601-1 (Ed. 3.1) testing to demonstrate safety and performance.

The software verification and validation testing further demonstrated that the software performs as intended and in accordance with specifications. The potential risks of HORIZON™ Therapy System have been identified and evaluated in compliance with ISO14971, and the risks were determined to be acceptable, or have been addressed with risk control measures.

The magnetic field characteristics of the system are identical to the predicate device, therefore equivalent safety and performance is assured. Consequently, no additional testing of the magnetic field characteristics of the system is necessary to meet the requirement of FDA's guidance document "Class II Special Controls Guidance Document: Repetitive Transcranial Magnetic Stimulation (rTMS) Systems" in order to demonstrate safety and performance.

In summary, performance testing demonstrates that the HORIZON™ Therapy System is as safe and effective as the predicate.

Device Description

The HORIZON™ Therapy System is a computerized, electromechanical medical device that produces and delivers non-invasive, magnetic stimulation using brief duration rapidly alternating, or pulsed, magnetic fields to induce electrical currents directed at spatially discrete regions of the cerebral cortex. This method of cortical stimulation by application of brief magnetic pulses to the head is known as Transcranial Magnetic Stimulation.

The HORIZON™ Therapy System is a non-invasive tool for the stimulation of cortical neurons for the treatment of Major Depressive Disorder in adult patients who have failed to achieve satisfactory improvement from antidepressant medication in the current episode. The HORIZON™ Therapy System is used for patient treatment by prescription only under the supervision of a licensed physician. It can be used in both inpatient and outpatient settings, including physicians' offices, clinics, and hospitals.

The HORIZON™ Therapy System is an integrated system consisting of a combination of hardware, software, and accessories. Its technological characteristics are described in further detail below.

Intended Use / Indications for Use

The HORIZON™ Therapy System 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.

Technological Characteristics

The HORIZON™ Therapy System is comprised of five principal components. These include:

    1. HORIZON™ User Interface;
    1. HORIZON™ Mainframe;
    1. HORIZON™ Power supply:
    1. HORIZON™ Air Film Coil;
    1. HORIZON™ MT Remote Coil;
    1. Accessory HORIZON™ Cart;
    1. Accessory Coil Holding Mechanism;
    1. Accessory Footswitch;
    1. Accessory Cables: and
    1. Accessory TMS Patient Caps.

The operator controls the HORIZON™ Therapy System via the HORIZON™ User Interface, using a graphic LCD panel with touchscreen technology. The operator instructions, given through the HORIZON™ User Interface, direct the HORIZON™ Mainframe in charging and discharging the device's high voltage discharge capacitor. The discharge is delivered to the patient via the stimulating coil. Motor threshold level can be determined using the HORIZON™ MT Remote Coil. Treatment is delivered to the treatment area via the HORIZON™ Air Film Coil, which is positioned above the treatment area. Positioning, and fixation, of the coil over the treatment area is accomplished using an Accessory Coil Holding Mechanism. The HORIZON™ Power Supply provides power to charge the high voltage capacitor in the HORIZON™ Mainframe.

Software documentation for a "moderate" level of concern has been provided.

Non-Clinical Testing

Electrical safety and electromagnetic compatibility ("EMC") testing was conducted on the system to demonstrate that the device is compliant with IEC 60601-1 (Ed. 3.1.) and IEC 60601-1-2 (2007). Environmental testing also demonstrated compliance with IEC 60601-1. The biocompatibility evaluation demonstrated that both coils meet ISO 10993-1 (2009) standards. In addition, acoustic output measurements have been conducted during IEC 60601-1 (Ed. 3.1) testing to demonstrate safety and performance.

The software verification and validation testing further demonstrated that the software performs as intended and in accordance with specifications. The potential risks of HORIZON™ Therapy System have been identified and evaluated in compliance with

5

ISO14971, and the risks were determined to be acceptable, or have been addressed with risk control measures.

As demonstrated in Section XIV and Appendix 03 the coil head geometry of both the HORIZON™ Air Film Coil and HORIZON™ MT Remote Coil are identical to the predicate devices, the Air Film Coil and D70mm MT Remote Coil, cleared under K143531 and K162935. For this reason, the magnetic field characteristics of the system are identical to the predicate device, therefore equivalent safety and performance is assured. Consequently, no additional testing of the magnetic field characteristics of the system is necessary to meet the requirement of FDA's guidance document "Class II Special Controls Guidance Document: Repetitive Transcranial Magnetic Stimulation (rTMS) Systems" in order to demonstrate safety and performance.

In summary, performance testing demonstrates that the HORIZON™ Therapy System is as safe and effective as the predicate.

Substantial Equivalence

The HORIZON™ Therapy System has the same intended use and indications for use, the same principles of operation, as well as the same key technological characteristics as the predicate device.

The design of the HORIZON™ Therapy System is substantially equivalent to the design of the predicate, as both systems are based on applying transcranial magnetic stimulation by means of repetitive pulse trains at a predetermined frequency. Both systems use the same mechanism of action, i.e., an electromechanical instrument that produces and delivers brief duration, rapidly alternating (pulsed) magnetic fields to induce electrical currents in localized regions of the prefrontal cortex.

The modifications from the predicate device include increased thermal performance and reliability of the mainframe and power supply and a new coil to mainframe connector to improve reliability and usability.

Transcranial magnetic stimulation is enabled in the HORIZON™ Therapy System and in the Rapid² Therapy System, as both have the same key system components, consisting of electromagnetic coils, a coil holding mechanism, a TMS stimulator and software. The operation procedure is the same in both the HORIZON™ Therapy System and the Rapid² Therapy System consisting of system setup, patient preparation, determination of patients' motor threshold, coil position, and administration of treatment at pre-defined treatment stimulation parameters. The similarities and minor differences between the HORIZON™ Therapy System and the Rapid2 Therapy System are described in Table 1.

The basic software capabilities related to treatment administration are the same as the predicate device.

The HORIZON™ Therapy System meets the same electrical and mechanical safety standards (IEC 60601-1) and the same EMC standards (IEC 60601-1-2).

Conclusions

In summary, the intended use and indications for use for the HORIZON™ Therapy System and the Rapid² Therapy System are identical. Furthermore, the key technological characteristics and principles of operation, including basic design, mechanism of action, specifications and treatment procedure are the same. Non-clinical test data demonstrates that the HORIZON™ Therapy System is as safe and effective as the predicate.

Thus, the HORIZON™ Therapy System is substantially equivalent to the Rapid? Therapy System.
