No
The summary describes a hardware-based system for transcranial magnetic stimulation with a predefined treatment protocol, and there is no mention of AI or ML in the device description, performance studies, or key metrics.
Yes
The device is indicated as an aid in short-term smoking cessation for adults, which directly addresses a health condition.
No
The device description and intended use state that it is a treatment device for short-term smoking cessation, not a diagnostic one.
No
The device description explicitly lists multiple hardware components including an Electromagnetic Coil, TMS Neurostimulator, Cooling System, Positioning System and Helmet, and Cart.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro (outside the body) for the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Description: The Brainsway Deep TMS System is described as a non-invasive system that applies magnetic pulses to the brain in vivo (within the body) to activate deep brain structures.
- Intended Use: The intended use is as an aid in short-term smoking cessation, which is a therapeutic application, not a diagnostic one based on analyzing bodily specimens.
- Mechanism of Action: The device works by inducing electric fields in brain tissue, directly interacting with the patient's body.
The Brainsway Deep TMS System is a therapeutic device that uses physical means (magnetic stimulation) applied directly to the patient's body. It does not involve the analysis of samples taken from the body.

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 scap. 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:

- Electromagnetic Coil
-
- TMS Neurostimulator

- Cooling System

Summary of Performance Studies
The efficacy of the Brainsway DTMS System indicated as an aid to short-term smoking cessation has been demonstrated in a prospective, double blind, randomized, sham controlled, multi-center trial. Subjects were randomly assigned to either active DTMS or Sham treatment.
Sample Size: N=262 (ITT-Safety population)
Study type: prospective, double blind, randomized, sham controlled, multi-center trial.
Key Results: The primary efficacy end-point, 4-week Continuous Quit Rate (CQR) was statistically significantly higher (p-value=0.0238) in the DTMS arm (17.1%) than in the sham arm (7.9%) for the ITT-Safety population, (N=262), up to 4 months follow-up. The number of cigarettes smoked per day (per diary entry) was statistically significantly lower in the DTMS treatment arm compared to the sham arm. The four-week CQR up to the 6th week visit was statistically significantly higher (p-value=0.0022) in DTMS arm (15.4%) than in the sham arm (4.3%).
Key Metrics
- 4-week Continuous Quit Rate (CQR): DTMS arm 17.1%, sham arm 7.9% (p-value=0.0238)

The primary efficacy end-point, 4-week Continuous Quit Rate (CQR) was statistically significant ly higher (p-value=0.0238) in the DTMS arm (17.1%) than in the sham arm (7.9%) for the ITT-Safety population, (N=262), up to 4 months follow-up. Based on the primary efficacy analysis of the study, the Brainsway DTMS has a positive treatment outcome and has demonstrated a beneficial effect in short-term smoking cessation. The higher 4-week CQR in the active DTMS arm is clinically
8
meaningful and statistically significant compared to the sham. Prognostic factors were assessed by adding the factors to the logistic model one at the time, except subject sex that is one of the covariates. The type III p-values were: 0.1816 for the subject sex, 0.9189 for the subject age, 0.6966 for the treatment question, 0.1238 for the age of smoking onset, and 0.7869 for the duration of smoking at baseline. None of the prognostic factors were found statistically significant. The primary efficacy endpoint of the study was substantiated by the secondary endpoints including the four-week CQR in subjects with at least 4 weeks of diary records in which the CQR was statistically significantly higher (p-value=0.0071) in the DTMS arm (27.3%) compared to the sham arm (11.3%)and the number of cigarettes smoked per day (per diary entry) was statistically significantly lower in the DTMS treatment arm compared to the sham arm. . In addition, the fourweek CQR up to the 6th week visit in which the CQR was statistically significantly higher (pvalue=0.0022) in DTMS arm (15.4%) than in the sham arm (4.3%).There were no individual adverse event types for which a significant difference between the study groups was found, except for application site discomfort and muscle twitching. Application site discomfort did not deter subjects from receiving the treatments.
The table below presents the most common adverse events reported in the clinical study in >5% or more of the patients who received the Brainsway DTMS Treatment or the sham (placebo) treatment. Safety information is provided from all patients who were treated in the clinical study.

Adverse Events
The differences in any of the reported adverse events in patients who received the Brainsway DTMS Treatment compared to patients who received the sham treatment, that were statistically significant, were application site discomfort and Muscle Twitching. The most frequent AE was headache reported by 24% of the subjects who received the DTMS treatment and by 18% of the subjects who received the Sham treatment. Reporting of Headaches was not statistically significantly different
9
between the treatment groups. The safety and efficacy results of the Multicenter DTMS clinical study presented above demonstrate the safety and effectiveness of the Brainsway DTMS System as an aid in short-term Smoking Cessation.
Substantial Equivalence:
The Brainsway DTMS System is substantially equivalent to the previously FDA-Cleared Brainsway Deep DTMS System (also manufactured by Brainsway Ltd., and the subject of De Novo (DEN170078). The De Novo Summary for the previous Brainsway Deep TMS Systems is provided in Appendix 12-1.

DISCUSSION OF SIMILARITIES AND DIFFERENCES:
The new Brainsway DTMS System and the predicate Brainsway DTMS System (DEN170078) are both identified under the same device classification (21 CFR 882.5802) for transcranial magnetic stimulation systems. The new Brainsway DTMS System is indicated for use as an aid in short-term smoking cessation. Heavy smoking (>10 cigarettes/day for more than 1 year) is considered an addiction, which is a psychiatric disorder or condition. The predicate device, Brainsway DTMS System (DEN170078) is intended for use as an adjunct for the treatment of adult patients suffering from OCD. Both indications for use fall under the classification regulation, 21 CFR 882.5802, for a transcranial magnetic stimulation system for neurological and psychiatric disorders and conditions.
The design and mechanism of action of the Brainsway DTMS System is similar to the design and mechanism of action of the previously cleared Brainsway DTMS System (DEN170078). The components are exactly the same, including the use of the same Magstim stimulators and the incorporation of an electromagnetic coil. Both coils are designed for effective activation of desired brain areas. The operational procedure is similar in both DTMS Systems, although the treatment stimulation parameters are different and appropriate for the relevant treatment administered. The differences in the coils, treatment stimulation parameters and resulting electromagnetic fields produced by the coils and the stimulation of the brain areas do not raise new or different questions of safety and effectiveness. Furthermore, performance testing, including the coil electrical and magnetic field distribution testing, demonstrates that the coil has output characteristics that are as safe as the predicate coil and the clinical performance testing, including the clinical results from the multicenter, Smoking Cessation clinical study, demonstrates that the coil is as effective as the predicate device in treating the specific psychiatric disorder/condition for which it is indicated to treat.
Conclusions:
In summary, the subject Brainsway DTMS System is substantially equivalent to the previous DeNovo granted predicate Brainsway DTMS System (DEN170078).
