K192833 is an FDA 510(k) clearance for the Indigo Aspiration System. Classified as Peripheral Mechanical Thrombectomy With Aspiration (product code QEW), Class II - Special Controls.

Submitted by Penumbra, Inc. (Alameda, US). The FDA issued a Cleared decision on December 20, 2019 after a review of 79 days - a notably fast clearance cycle.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.5150 - 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.

Device Classification

Product Code QEW Peripheral Mechanical Thrombectomy With Aspiration
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 870.5150
Definition To Mechanically Disrupt Thrombus And/or Debris Prior To Removal From The Peripheral Vasculature Through Aspiration.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. Clinical trial data may be submitted as supporting evidence to strengthen the substantial equivalence argument. Most Cardiovascular devices follow this clearance model.
