K920429 is an FDA 510(k) clearance for the MODIFIED MODEL M1403A TELEMETRY MONITORING SYSTEM. Classified as Monitor, St Segment With Alarm (product code MLD), Class II - Special Controls.

Submitted by Hewlett-Packard Co. (Waltham, US). The FDA issued a Cleared decision on July 20, 1993 after a review of 533 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.1025 - 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.
