Intended Use

The Provox FreeHands FlexiVoice combines pulmonary rehabilitation using a Heat and Moisture Exchanger with voice rehabilitation using an Automatic Speaking Valve or Manual Occlusion, in laryngectomized patients using a voice prosthesis. The entire device is for single patient use and the HME-part is for single use, i.e, it has to be exchanged at least every 24 hours. Environments of use include: Hospitals, ICU, sub-acute care institutions and home.

Device Story

Device combines heat and moisture exchanger (HME) with automatic speaking valve for laryngectomized patients using voice prosthesis; eliminates need for manual finger occlusion during speech. Consists of reusable speech valve housing with interchangeable membranes (Light, Medium, Strong) and disposable HME cassette. Operates via air pressure; valve remains open for inhalation; user turns top to activate valve for speech; returns to free exhalation during normal breathing. Used in home, hospital, and ICU settings; operated by patient. HME provides humidity and protects valve from mucus. Benefits include restored speech capability and pulmonary health. Device attaches to Provox base plates or LaryTubes.

Clinical Evidence

Bench testing only. Testing included verification of closing flow, opening pressure, cough-out pressure, moisture loss, airflow resistance, leakage, attachment/detachment forces, and durability. Simulated use testing (usability study) and fatigue/climate/aging/transport testing were performed. Risk management conducted per ISO 14971.

Technological Characteristics

Materials: Silicone and plastic. Sensing/Actuation: Air pressure-operated one-way valve. Form factor: 22mm connector interface. Connectivity: None. Sterilization: Not specified. Software: None.

Indications for Use

Indicated for laryngectomized patients using a voice prosthesis requiring pulmonary rehabilitation and voice restoration. Contraindicated for patients unable to remove or operate the device.

Regulatory Classification

Identification

A laryngeal prosthesis (Taub design) is a device intended to direct pulmonary air flow to the pharynx in the absence of the larynx, thereby permitting esophageal speech. The device is interposed between openings in the trachea and the esophagus and may be removed and replaced each day by the patient. During phonation, air from the lungs is directed to flow through the device and over the esophageal mucosa to provide a sound source that is articulated as speech.

Special Controls

*Classification.* Class II (special controls). The device, when it is a voice amplification device, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

## Device Description:

The Provox FreeHands consists of two functional units that work together, a speech valve unit in a reusable housing and a disposable Provox FreeHands HME Cassette, which is connected to the lower part of the valve housing before it is ready to use.

The speech valve unit allows hands-free tracheostoma occlusion for voice prosthesis users. It has three interchangeable membranes (Light, Medium and Strong).

The HME unit of the Provox® FreeHands HME® is a full heat-and-moisture-exchanger, which is used for partial restoration of the lost upper airway functions. It also separates the speech valve from direct contact with the airway and, thus, prevents mucous from being coughed into the valve part of the device. It also reduces the risk of inhalation of small particles, e.g., coming from a defective valve.

After proper adjustment and attachment of the speech valve unit and HME cassette, the completed Provox FreeHands HME is inserted into either Provox Adhesive base plate or Provox LaryTube with ring.

### Indications for Use:

The Provox FreeHands FlexiVoice combines pulmonary rehabilitation using a Heat and Moisture Exchanger with voice rehabilitation using an Automatic Speaking Valve or Manual Occlusion, in laryngectomized patients using a voice prosthesis.

#### Summary of Non-Clinical Testing:

The following tests were performed to verify that Provox FreeHands FlexiVoice met applicable safety and performance requirements.

The main focus areas of testing were:

- Verification of the closing flow, opening pressure, cough-out pressure, moisture loss, airflow resistance and leakage test.
- Verification of attachment and detachment forces in the different interfaces including the durability of the devices.
- . Simulated use of all FreeHands FlexiVoice products and their IFUs.
- Verification of FreeHands FlexiVoice products' function after fatigue test, climate testing, aging and transport.

In addition, risk management according ISO 14971 and simulated use testing (usability study) has been conducted.

A comparative analysis shows that the Provox FreeHands FlexiVoice closes at approximately the same flow rate as the predicate Provox FreeHands HME. Only a small adjustment has been made in the closing flow based on experience from usage of Provox FreeHands HME.

Additionally, moisture loss, flow resistance and air leakage of the two devices are very similar. The flow resistance of Provox FreeHands FlexiVoice is a bit lower than Provox FreeHands. This is also based on experience from usage of Provox FreeHands HME. We therefore conclude that key properties of the devices are equivalent in terms of working principle, safety and effectiveness.
