K771361 is an FDA 510(k) clearance for the PHYSIOLOGICAL PRESSURE TRANSDUCER 1290A. Classified as Transducer, Blood-pressure, Extravascular (product code DRS), Class II - Special Controls.

Submitted by Hewlett-Packard Co. (Mchenry, US). The FDA issued a Cleared decision on August 4, 1977 after a review of 10 days - a notably fast clearance cycle.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.2850 - 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.

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.
