K951832 is an FDA 510(k) clearance for the LASERFLO BLOOD PERFUSION SINGLE USE PROBES MODELS SUP-440, SUPR-434 SUP-433. Classified as Probe, Blood-flow, Extravascular (product code DPT), Class II - Special Controls.

Submitted by Vasamedics, LLC (Saint Paul, US). The FDA issued a Cleared decision on March 21, 1996 after a review of 336 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.2120 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Cardiovascular review framework, consistent with the majority of Class II 510(k) submissions.
