K020738 is an FDA 510(k) clearance for the AVITA BF1 (VITALIO) BODY FAT ANALYZER. Classified as Analyzer, Body Composition (product code MNW), Class II - Special Controls.

Submitted by Avita Corporation (Flagstaff, US). The FDA issued a Cleared decision on May 22, 2003 after a review of 442 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 870.2770 - the FDA gastroenterology and urology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Gastroenterology & Urology submissions.
