K133995 is an FDA 510(k) clearance for the NEURON-SPECTRUM-4/P WITH NEURON-SPECTRUM.NET SOFTWARE. Classified as Non-normalizing Quantitative Electroencephalograph Software (product code OLT), Class II - Special Controls.

Submitted by Neurosoft , Ltd. (Abano Terme, Padova, IT). The FDA issued a Cleared decision on June 19, 2015 after a review of 540 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.
