K160509 is an FDA 510(k) clearance for the Tiger 2 Self-Advancing Nasal Jejunal Feeding Tube. Classified as Tubes, Gastrointestinal (and Accessories) (product code KNT), Class II - Special Controls.

Submitted by Cook Incorporated (Bloomington, US). The FDA issued a Cleared decision on May 18, 2017 after a review of 449 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.5980 - 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.
