K921315 is an FDA 510(k) clearance for the PENTAX XENON LIGHT SOURCE. Classified as Light Source, Endoscope, Xenon Arc (product code GCT), Class II - Special Controls.

Submitted by Pentax Precision Instrument Corp. (Orangeburg, US). The FDA issued a Cleared decision on June 25, 1993 after a review of 464 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Gastroenterology & Urology FDA review panel, regulated under 21 CFR 876.1500 - 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.
