K940121 is an FDA 510(k) clearance for the IMPLANTERS/ADJUSTABLE/ANDERSON'S MARKERS. Classified as System, Applicator, Radionuclide, Manual (product code IWJ), Class I - General Controls.

Submitted by Best Industries (Springfield, US). The FDA issued a Cleared decision on December 30, 1994 after a review of 354 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.5650 - 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.
