K953893 is an FDA 510(k) clearance for the PARATREND 7 INTRAVASCULAR BLOOD GAS MONITORING SYSTEM. Classified as Analyzer, Gas, Carbon-dioxide, Partial Pressure, Blood-phase, Indwelling (product code CCC), Class II - Special Controls.

Submitted by Biomedical Sensors, Inc. (High Wycombe, Buckinghamshire, GB). The FDA issued a Cleared decision on November 4, 1997 after a review of 810 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1150 - the FDA anesthesiology and respiratory device 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 Anesthesiology submissions.

CCC Device Classification - Class 2, Special Controls

Product Code CCC Analyzer, Gas, Carbon-dioxide, Partial Pressure, Blood-phase, Indwelling
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 868.1150
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 Anesthesiology devices follow this clearance model.
