K910850 is an FDA 510(k) clearance for the PSF-50ET. Classified as Transducer, Ultrasonic, Diagnostic (product code ITX), Class II - Special Controls.

Submitted by Toshiba America Medical Systems, In.C (Tustin, US). The FDA issued a Cleared decision on January 29, 1992 after a review of 336 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Radiology review framework, consistent with the majority of Class II 510(k) submissions.
