NCT07021833

Brief Summary

This is a prospective, multicenter, non-randomized single-arm safety and performance study to collect data to evaluate the safety of the Cryosa procedure to treat obstructive sleep apnea (OSA) in patients with moderate to severe OSA. The study will also evaluate the chronic performance of the Cryosa system and collect clinical measures for therapy effectiveness that will be used to demonstrate safety and effectiveness in the next clinical study.
