K844772 is an FDA 510(k) clearance for the 6.0 MHZ LA6060 TRANSDUCER & 4.0 MHZ LA4011 TRANSDU. Classified as Transducer, Ultrasonic, Diagnostic (product code ITX), Class II - Special Controls.

Submitted by Philips Medical Systems, Inc. (5680 Da Best, NL). The FDA issued a Cleared decision on April 17, 1986 after a review of 498 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.
