K072094 is an FDA 510(k) clearance for the CHOOSTENT. Classified as Prosthesis, Esophageal (product code ESW), Class II - Special Controls.

Submitted by M.I. Tech Co., Ltd. (Deerfield, US). The FDA issued a Cleared decision on September 25, 2008 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 878.3610 - 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.
