The description focuses on mechanical vibration and frequency generation, with no mention of AI/ML terms or capabilities.
Yes.
The device's intended use is to provide airway clearance therapy and promote bronchial drainage for patients with various respiratory ailments, which aligns with the definition of a therapeutic device.
No
Explanation: The device is described as providing "airway clearance therapy" and inducing vibrations to loosen mucus, which are therapeutic actions. Its purpose is to treat conditions, not to diagnose them.
No
The device description explicitly states it includes hardware components: an electro-acoustical transducer ("Power Head") and a frequency generator.
Based on the provided information, the Frequencer™ is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
- Frequencer™ Function: The Frequencer™ is a device that applies external vibration to the chest wall to help clear airways and promote bronchial drainage. It interacts directly with the patient's body and does not involve testing samples taken from the body.
Therefore, the Frequencer™ falls under the category of a therapeutic or physical therapy device, not an IVD.

Intended Use / Indications for Use
The Frequencer™ provides airway clearance therapy and promotes bronchial drainage by inducing vibration in the chest walls. This device is intended to be a component of postural drainage therapy by providing a convenient method of external thorax manipulation.
It is indicated for patients having respiratory ailments which involve defective mucociliary clearance, as is typical in patients suffering from cystic fibrosis as well as chronic bronchitis, bronchiectasis, ciliary dyskinesia syndromes, asthma. muscular dystrophy, neuromuscular degenerative disorders, post-operative atelectasis and thoracic wall defects. Indications for this form of therapy are described in the Clinical Practice Guidelines for Postural Drainage Therapy of the American Association for Respiratory Care (AARC) published in 1991. This particular device provides a gentler, less painful form of therapy than the traditional "clapping" method of postural drainage therapy, allowing it to be used on patients who cannot be treated by clapping.

Device Description
The Frequencer™ provides airway clearance therapy and promotes bronchial drainage by inducing vibration in the chest walls. It induces oscillatory sound waves in the chest by means of an electro-acoustical transducer (hereafter referred to as the "Power Head") which is placed externally on the patient's chest. The Power Head is connected to a frequency generator which is capable of producing frequencies between 20 and 100 Hz. The Power Head induces sound waves in the patient's chest which are effective in loosening mucus deposits.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The efficacy of the Frequencer™ as compared to CCPT was assessed in a clinical trial on 20 adult patients suffering from cystic fibrosis (CF). The results show that use of the Frequencer™ results in comparable quantities of expelled sputum per session as using CCPT (9.24 ± 1.62 g for the Frequencer™ vs. 9.27 ± 1.62 g for CCPT).

The Frequencer™ provides airway clearance therapy and promotes bronchial drainage by inducing vibration in the chest walls.

muscular dystrophy, neuromuscular degenerative disorders, post-operative atelectasis and thoracic wall defects.
Comparison of Technological Characteristics:
The Frequencer™ is similar to the predicate devices in terms of indications for use, contra-indications, and the intent to create vibrations in the chest wall via external stimulation. The operating principle of the proposed device differs from those of the predicate devices. Rather than mechanical percussion (Electro-Flo Percussor Model 5000), airflow-induced air pulses which are transferred through the air in the patient's throat (Flutter® D Mucus Clearance Device), or pneumatically created pressure oscillations (AbiVest™ Airway Clearance System, Medpulse™ Respiratory Vest System, Model 1000, Thairapy® Vest System), the Frequencer uses sound wave pulses from a transducer to stimulate vibration in the chest wall.
Performance Testing
Conventional chest physiotherapy (CCPT) typically involves forces externally applied to the patient's chest of 58.10 +/- 15.32 N (13.06 +/- 3.44 lb). The Frequencer™ uses much smaller forces, namely 0.4 - 3 N (0.090 - 0.674 Ib). Technological data for pneumatic vests are typically expressed in units of pressure and therefore do not allow a basis for direct comparison. Frequencies for CCPT are typically 6.6 Hz, pneumatic vests (AbiVest™ Airway Clearance System, Medpulse™ Respiratory Vest System, Model 1000, Thairapy® Vest System) and the mechanical percussor (Electro-Flo Percussor Model 5000) are capable of delivering roughly 5-25 Hz. The Frequencer™ can deliver a range of frequencies from 20-100 Hz. The actual operating frequency is selected by varying until the patient feels a sympathetic resonance in the chest.
Clinical Data:
The efficacy of the Frequencer™ as compared to CCPT was assessed in a clinical trial on 20 adult patients suffering from cystic fibrosis (CF). The results show that use of the Frequencer™ results in comparable quantities of expelled sputum per session as using CCPT (9.24 ± 1.62 g for the Frequencer™ vs. 9.27 ± 1.62 g for CCPT). This is despite the fact that patients treated with the Frequencer were sitting, while those receiving CCPT were lying down, thus benefiting from postural drainage.
Conclusions:
The proposed Frequencer™ has the identical indications and intended use as well as comparable technological characteristics as the predicate devices. Only the operating principle differs, being electro-acoustic rather than pneumatic or electro-mechanical. Safety and efficacy have been demonstrated in both laboratory and clinical settings. Thus, the proposed Frequencer™ is substantially equivalent to the predicate devices.
