K250225 is an FDA 510(k) clearance for the Bolt Intravascular Lithotripsy (IVL) System. Classified as Percutaneous Catheter, Ultrasound (product code PPN), Class II - Special Controls.

Submitted by Bolt Medical, Inc. (Carlsbad, US). The FDA issued a Cleared decision on March 25, 2025 after a review of 57 days - a notably fast clearance cycle.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.1250 - 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.
