K890531 is an FDA 510(k) clearance for the EUP-F124 5.0 MHZ CONVEX ARRAY FINGER TOP PROBE. Classified as Transducer, Ultrasonic, Diagnostic (product code ITX), Class II - Special Controls.

Submitted by Hitachi Medical Corp. of America (Tarrytown, US). The FDA issued a Cleared decision on April 13, 1990 after a review of 435 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1570 - 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.
