K801339 is an FDA 510(k) clearance for the TELEMETRY DECODER. Classified as Implantable Pacemaker Pulse-generator (product code DXY), Class III - Premarket Approval.

Submitted by Intermedics, Inc. (Mchenry, US). The FDA issued a Cleared decision on September 23, 1981 after a review of 476 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.3610 - 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. High regulatory complexity 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.
