K223228 is an FDA 510(k) clearance for the Dayspring. Classified as Sleeve, Limb, Compressible (product code JOW), Class II - Special Controls.

Submitted by Koya Medical, Inc. (Oakland, US). The FDA issued a Cleared decision on January 4, 2024 after a review of 443 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.5800 - 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.
