K924850 is an FDA 510(k) clearance for the VANSONNENBERG GASTROSTOMY CATHETER. Classified as Tubes, Gastrointestinal (and Accessories) (product code KNT), Class II - Special Controls.

Submitted by Boston Scientific Corp (San Jose, US). The FDA issued a Cleared decision on December 29, 1994 after a review of 822 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.
