The United States is currently experiencing an increase in the incidence and prevalence of
obstructive sleep apnea (OSA). With prevalence in middle-aged adults of 2 to 4% of the
population, untreated OSA has been implicated in increased risk for cardiovascular disease,
including hypertension and heart failure, daytime sleepiness, and increased risk of motor
vehicle accidents.

This study was design in order to evaluate the CelonProSleep plus for multi-level
radiofrequency ablation (RFA) of the palate and base of tongue as a treatment for mild to
moderate obstructive sleep apnea syndrome (OSAS).


Inclusion Criteria:

- Adults (≥ 22 years)

- Self-report of daytime somnolence

- Body mass index (BMI) ≤ 32

- Mild to moderate obstructive sleep apnea (AHI 10 - 30; lowest O2 sat ≥ 80%)

- Evidence of palate and tongue base collapse on supine fiberoptic examination

- Non-compliant with or refusal of continuous positive airway pressure therapy (CPAP) (<
4 hours per night by patient report)

- No prior surgical treatment for OSAS other than nasal surgery

- Willing and capable of providing informed consent

Exclusion Criteria:

- Another significant sleep disorder (e.g., insomnia, periodic limb movement)

- Tonsillar hypertrophy

- Chronic Obstructive Pulmonary Disease (COPD)

- Interstitial Lung Disease (ILD)

- Cystic Fibrosis

- Acute Repiratory Distress Syndrome (ARDS)

- Nasal or supraglottic obstruction on fiberoptic examination

- American Society of Anesthesiologists (ASA) class III ,IV, V

- Latex allergy

- Lidocaine allergy

- Pregnancy or plans to become pregnant Note: women of childbearing potential must
demonstrate a negative pregnancy test upon enrollment; those patients qualified to
progress to RFA must also demonstrate a negative pregnancy test within 7 days prior to
the date of RFA procedure.

- Major depression or non-stabilized psychiatric disorder

- Drug or alcohol abuse

- Previous palatal or tongue surgery

- Stable or unstable angina

- congestive heart failure (CHF)

- moderate or severe valvular disease

- transient ischemic attack (TIA)/cardiovascular accident (CVA)

- Carotid stenosis or endarterectomy

- Anemia

- Room air oxygen saturation (SpO2) < 95%

- Pulmonary hypertension

- Dialysis

- Central or mixed apnea ≥ 10% of respiratory events

- Participation in another clinical study (enrolled in any concurrent study) whose
investigational plan is judged to interfere or affect any of the measures of this
study
