K961848 is an FDA 510(k) clearance for the 3M LITTMANN ELECTRONIC STETHOSCOPE. Classified as Stethoscope, Electronic (product code DQD), Class II - Special Controls.

Submitted by Minnesota Mining and Mfg. Co. (St. Paul, US). The FDA issued a Cleared decision on September 26, 1997 after a review of 501 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.1875 - 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.
