K163661 is an FDA 510(k) clearance for the P-140-Flex Coil, Na-140-Flex Coil, C-140-Flex Coil. Classified as Coil, Magnetic Resonance, Specialty (product code MOS), Class II - Special Controls.

Submitted by Rapid Biomedical GmbH (Rimpar, DE). The FDA issued a Cleared decision on March 21, 2018 after a review of 449 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1000 - 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.
