K895435 is an FDA 510(k) clearance for the FRESENIUS AS 104 CELL SEPARATOR. Classified as Separator, Automated, Blood Cell And Plasma, Therapeutic (product code LKN).

Submitted by Fresenius USA, Inc. (Concord, US). The FDA issued a Cleared decision on November 2, 1990 after a review of 421 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel. 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.
