K021560 is an FDA 510(k) clearance for the MODIFICATION TO AMERIWATER PURIFICATION SYSTEM FOR HEMODIALYSIS. Classified as Subsystem, Water Purification (product code FIP), Class II - Special Controls.

Submitted by Ameriwater (Dayton, US). The FDA issued a Cleared decision on August 14, 2003 after a review of 458 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.5665 - 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.
