K971975 is an FDA 510(k) clearance for the CARDIMA PATHFINDER 1.5F MAPPING MICROCATHETER. Classified as Catheter, Electrode Recording, Or Probe, Electrode Recording (product code DRF), Class II - Special Controls.

Submitted by Cardima, Inc. (Fremont, US). The FDA issued a Cleared decision on July 1, 1998 after a review of 398 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Cardiovascular review framework, consistent with the majority of Class II 510(k) submissions.
