Intended Use

The Enchant AllPEP is intended for use as a Positive Expiratory Pressure (PEP) by patients aged 18 years and older. Patients must be capable of generating an exhalation flow of 10 lpm for 3-4 seconds to promote secretion clearance. This device may be used to prevent or reverse atelectasis and as an inspiratory, deep breathing positive exerciser. It may be used in hospital and clinical settings.

Device Story

AllPEP is a Positive Expiratory Pressure (PEP) device used in hospital and clinical settings to promote secretion clearance and prevent/reverse atelectasis. Device consists of housing, top cover, and internal swinger mechanism. Patient inhales room air through one-way valve; during exhalation, air is directed through upper portion of device where swinger mechanism oscillates air, creating vibration. Device provides PEEP and oscillations during exhalation. Healthcare providers use device to assist patients in respiratory therapy; output is physical vibration and pressure during exhalation. Benefits include improved airway clearance and lung expansion. Device is single-patient, multi-use, intended for replacement every 30 days.

Clinical Evidence

Bench testing only. Testing included aging/post-aging performance, cleaning validation, post-cleaning performance, frequency (Hz), amplitude (cmH2O), and pressure at min/max settings. Biocompatibility testing performed per ISO 10993-1 (cytotoxicity, sensitization, intracutaneous reactivity, material-mediated pyrogenicity, chemical characterization) and ISO 18562 (particulate matter, VOCs). Results met pre-defined acceptance criteria.

Technological Characteristics

PEP device featuring swinger mechanism for oscillation and one-way valve for inhalation. Materials meet ISO 10993-1 for external communicating, mucosal membrane contact, prolonged duration (>24h, <30 days). Performance metrics: frequency range 9.82-16.32 Hz and amplitude 3.24-9.17 cmH2O across 5-30 lpm flow rates. Mechanical operation; no energy source required. Single-patient, multi-use; cleaned with neutral dishwashing agent.

Indications for Use

Indicated for patients 18 years and older requiring secretion clearance or prevention/reversal of atelectasis; must be capable of generating 10 lpm exhalation flow for 3-4 seconds.

Device Description: AllPEP provides PEEP during user exhalation and features a mechanism which provides oscillations during exhalation as well.

Principle of Operation: The oscillating positive exhalation pressure device, AllPEP, includes a housing, a top cover, and an oscillating mechanism. The patient inhales room air through a one-way valve and when exhaling the exhaled gas is directed through the upper portion of the device which contains a swinger mechanism to oscillate the air, causing the air to vibrate.

### Indications for Use:

The Enchant AllPEP is intended for use as a Positive Expiratory Pressure (PEP) by patients aged 18 years and older. Patients must be capable of generating an exhalation flow of 10 lpm for 3-4 seconds to promote secretion clearance. This device may be used to prevent or reverse atelectasis and as an inspiratory, deep breathing positive exerciser. It may be used in hospital and clinical settings.

### Patient Population:

Patients 18 years and older who are capable of generating an exhalation flow of 10 1pm for 3-4 seconds.

{5}------------------------------------------------

### Environments of use:

For hospital and clinical settings.

### Substantial Equivalence Discussion

The table below compares the key features of the proposed with the identified predicate - DHD Acapella K991561. The comparison demonstrates that the subject device is substantially equivalent to the predicate device.

#### . Indications for Use -

The indications for use are similar for the subject device when compared to the predicate device.

Discussion - Since the predicate, newer cleared PEP devices have more details within the indications for use. We have added this information, it does not however raise different questions of safety or effectiveness.

#### . Technology and construction -

The technology and principle of operation is similar for the subject device when compared to the predicate device.

Discussion - While the predicate may have a different means of creating oscillation, there are a number of cleared PEP devices which also have slightly different ways of creating oscillations during the exhalation cycle. This difference does not raise different concerns of safety or effectiveness.

#### . Environment of Use -

The environments of use are similar to predicate which are hospital and clinical settings. Discussion - The environments of use are similar.

#### Patient Population -.

The patient population for the subject device is patients requiring secretion clearance and those who may have atelectasis. They should be capable of generating an exhalation flow of 10 lpm for 3-4 seconds.

Discussion - The subject and predicate device patient populations are similar.

### Non-Clinical Testing Summary -

### Bench testing -

The following tests were performed to demonstrate substantial equivalence:

- Aging and post-aging performance ●
- Cleaning validation ●
- Post-cleaning performance
- Frequency (Hz)
- Amplitude (cmH20) ●
- Pressure at min / max settings (cmH20) 0

Discussion - The test results are similar to the predicate and within pre-defined acceptance criteria.

{6}------------------------------------------------

## Biocompatibility -

According to ISO 10993-1 and the FDA Guidance related to biocompatibility from 2020, the subject device is considered:

- External Communicating
- Tissue Contacting
- Prolonged duration of use (>24 hours, <30 days) o

For those materials in direct contact, they would be considered:

- Surface Device
- Mucosal Membrane ●
- o Prolonged duration of use (>24 hours, <30 days)

Based upon ISO 10993-1, the sponsor has performed the following biocompatibility tests for the subject device:

- ISO 10993-5:2009 - Cytotoxicity
- ISO 10993-10:2010 Sensitization and Intracutaneous Reactivity ●
- ISO 10993-11:2017 Material-Mediated Pyrogenicity ●
- ISO 10993-18:2020 Chemical Characterization and Risk Assessment ●
- ISO 18562-2:2018 Particulate Matter testing ●
- ISO 18562-3:2018 Volatile Organic Compounds (VOC) with risk assessment ●

Discussion - The subject device was found to meet the applicable requirements for biocompatibility safety for the intended population.

### Discussion of Differences

There are no significant differences in indications for use, population, use environments, technological characteristics or performance which raise different concerns of safety compared to the predicate and thus should be found to be substantially equivalent.

### Substantial Equivalence Conclusion

Through performance testing, design, and non-clinical testing the proposed device and predicate have been found to be substantially equivalent.
