K941553 is an FDA 510(k) clearance for the MAGNES II BIOMAGNETOMETER. Classified as Source Localization Software For Electroencephalograph Or Magnetoencephalograph (product code OLX), Class II - Special Controls.

Submitted by Biomagnetic Technologies, Inc. (San Diego, US). The FDA issued a Cleared decision on May 16, 1996 after a review of 778 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.1400 - 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.
