K905536 is an FDA 510(k) clearance for the FETAL DOPPLER. Classified as Monitor, Fetal Doppler Ultrasound (product code MAA), Class II - Special Controls.

Submitted by Toshiba America Medical Systems, In.C (Tustin, US). The FDA issued a Cleared decision on April 21, 1992 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 884.2660 - 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.
