K923529 is an FDA 510(k) clearance for the DMS DATA MANAGEMENT SYSTEM/DRS-4 DIALYZER REPROCES. Classified as Dialyzer Reprocessing System (product code LIF), Class II - Special Controls.

Submitted by Seratronics, Inc. (Walnut Creek, US). The FDA issued a Cleared decision on August 29, 1994 after a review of 774 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.5820 - 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.
