Submitted by Fresenius Medical Care Renal Therapies Group, LLC (Waltham, US). The FDA issued a Cleared decision on May 11, 2023 after a review of 423 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.5860 - 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.
