Summary

This trial evaluates the safety and performance of a new treatment for moderate-severe OSA. It will also collect data to prove its effectiveness.

Who is the study for?
Adults aged 22-70 with moderate to severe obstructive sleep apnea who can't or won't use PAP or MAD devices, have a BMI of ≤ 40 kg/m2, and are non-smokers. They must be able to consent and live near the study site. Exclusions include general anesthesia risks, recent upper airway surgery, resistant hypertension, certain heart conditions, neuromuscular diseases, active severe lung disease including COVID-19 complications.
What is being tested?
The Cryosa procedure is being tested for safety and effectiveness in treating obstructive sleep apnea (OSA). This single-arm study involves participants with moderate to severe OSA who will undergo the procedure and then be monitored to assess its performance over time.
What are the potential side effects?
While specific side effects are not listed here, potential risks may include those commonly associated with medical procedures such as pain at the treatment site, swelling, infection risk from wounds or general anesthesia-related complications.
