Product Code DRO Pacemaker, Cardiac, External Transcutaneous (non-invasive)
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 870.5550
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Cardiovascular devices follow this clearance model.
