K931794 is an FDA 510(k) clearance for the MARINR SERIES EP DIAGNOSTIC CATHETERS. Classified as Catheter, Electrode Recording, Or Probe, Electrode Recording (product code DRF), Class II - Special Controls.

Submitted by Medtronic Cardiorhythm (San Jose, US). The FDA issued a Cleared decision on June 6, 1994 after a review of 420 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.1220 - the FDA cardiovascular device 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 Cardiovascular submissions.
