K933055 is an FDA 510(k) submission (not cleared) for the MEDTRONIS(R) PACING LEADS AND LEAD ADAPTORS, MODIF. Classified as Permanent Pacemaker Electrode (product code DTB), Class III - Premarket Approval.

Submitted by Medtronic Vascular (Minneapolis, US). The FDA issued a Not Cleared (DENG) decision on May 2, 1994 after a review of 340 days.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.3680 - the FDA cardiovascular device oversight framework. The Traditional 510(k) pathway requires demonstration of substantial equivalence to a legally marketed predicate device - a standard the FDA determined was not met in this submission.

Device pattern: Regulatory edge-case submission. High predicate equivalence gap. With 340 days under review and no clearance granted, this submission reflects a case where the FDA could not confirm sufficient predicate equivalence - often indicating either a novel device category or unresolved safety and performance questions.
