K140740 is an FDA 510(k) clearance for the TRANSONIC TISSUE PERFUSION MONITOR. Classified as Flowmeter, Blood, Cardiovascular (product code DPW), Class II - Special Controls.

Submitted by Transonic Systems, Inc. (Ithaca, US). The FDA issued a Cleared decision on July 23, 2015 after a review of 485 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.2100 - 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.
