K913556 is an FDA 510(k) clearance for the IVALON EMBOLIZATION PARTICLES. Classified as Device, Neurovascular Embolization (product code HCG), Class II - Special Controls.

Submitted by Ivalon (San Diego, US). The FDA issued a Cleared decision on April 13, 1994 after a review of 978 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.5950 - the FDA neurology 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 Neurology submissions.
