K936236 is an FDA 510(k) clearance for the SHIMADZU IMAGE AMPLIFIER IA-12LM SERIES. Classified as System, X-ray, Fluoroscopic, Image-intensified (product code JAA), Class II - Special Controls.

Submitted by Shimadzu Medical Systems (Torrance, US). The FDA issued a Cleared decision on May 11, 1995 after a review of 497 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1650 - the FDA radiology and imaging software oversight 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 Radiology submissions.
