K911139 is an FDA 510(k) clearance for the HEWLETT-PACKARD MODELS M1400A, M1402A & M1401A. Classified as Monitor, Cardiac (incl. Cardiotachometer & Rate Alarm) (product code DRT), Class II - Special Controls.

Submitted by Hewlett-Packard Co. (Waltham, US). The FDA issued a Cleared decision on June 11, 1991 after a review of 89 days - a notably fast clearance cycle.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.2300 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
