Intended Use

The DeltaWave Nasal Pillow System is intended to noninvasively channel pressurized airflow to a patient from a Continuous Positive Airway Pressure (CPAP) or Bi-Level medical device. This medical device is intended for adult patients weighing 66lbs (30kg), and for whom noninvasive Continuous Positive Airway Pressure (CPAP) or Bi-Level therapy has been prescribed by a physician or other authorized healthcare professional. It is intended for single-patient reuse in the home.

Device Story

DELTAWAVE Nasal Pillows System; non-invasive interface for CPAP/Bi-Level therapy. Device channels pressurized air from machine to patient nostrils; nasal pillows gently dilate nostrils to reduce flow restriction and pressure drop. Components include cannula/mask, head strap, retainer bars, tubing, and swivel adapters. Used in home environment by patients; prescribed by physicians. Healthcare providers use device to deliver prescribed airway pressure therapy; patient benefits from reduced driving pressure requirements and effective sleep apnea treatment. Device connects to standard CPAP via 22mm tubing.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing: cleaning validation, shelf-life/storage, CO2 rebreathing, dead space, pressure-flow/leakage, resistance to flow, vibration/noise, and biocompatibility (ISO 10993, ISO 18562).

Technological Characteristics

Nasal pillow interface; 22mm conical connector; non-sterile; single-patient reusable. Materials evaluated per ISO 10993 and ISO 18562. Operates with CPAP/Bi-Level devices (4-20 cmH2O). Complies with ISO 17510 (mask performance) and ISO 5356-1 (connectors).

Indications for Use

Indicated for adult patients ≥66 lbs (30kg) prescribed noninvasive CPAP or Bi-Level therapy for sleep apnea. Intended for single-patient home use.

Regulatory Classification

Identification

A noncontinuous ventilator (intermittent positive pressure breathing-IPPB) is a device intended to deliver intermittently an aerosol to a patient's lungs or to assist a patient's breathing.

Dear Judy Strzepek:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

subject device is a type of medical device prescribed by a physician or authorized professional for patients who have been diagnosed with Sleep Apnea.

The subject device is designed to prevent pressure drop from the CPAP machine to the patient's nasal passages. That is accomplished by maintaining the same, or greater flow space from the machine output to the patient's nostrils. To further ensure the least amount of pressure drop the nasal pillows are designed to gently dilate the patient's nostrils to avoid restrictions to incoming air entering the nostrils. This allows air to enter the patient's nostrils at a lower driving pressure. Table 1 provides a list of the subject device components with the number of each provided to the patient in a system.

# 10. CONCLUSION

The differences between the subject device and predicate do not raise new/different questions of safety and effectiveness. ন্নীন conclusions drawn from the nonclinical tests (discussed above) demonstrate that the device is as safe and as effective as the predicate device. The Deltawave Nasal Pillow System is substantially equivalent to the F&P EVORA Nasal Mask Model A.
