The US Food and Drug Administration accepted the premarket 510(k) notification for Itamar-Medical’s Watch-PAT200, a product designed to diagnose and evaluate patients with obstructive sleep apnea.

The Watch-PAT200 is less than half the size of its predecessor, the Watch-PAT100, and provides clinical data including apnea-hypopnea index, oxygen desaturation levels, sleep time, and sleep phases, including REM, without requiring a nasal cannula or EEG electrodes.

The Watch-PAT200 was presented at the Itamar-Medical booth at the annual meeting of the Associated Professional Sleep Societies in Baltimore and will be available for purchase starting August 2008.
