K211120 is an FDA 510(k) clearance for the ERIC Retrieval Device. Classified as Catheter, Thrombus Retriever (product code NRY), Class II - Special Controls.

Submitted by MicroVention, Inc. (Aliso Viejo, US). The FDA issued a Cleared decision on March 31, 2022 after a review of 350 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 870.1250 - the FDA neurology 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Neurology review framework, consistent with the majority of Class II 510(k) submissions.

Device Classification

Product Code NRY Catheter, Thrombus Retriever
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 870.1250
Definition The Device Is Intended To Restore Blood Flow By Removing Thrombus/clots In Patients Experiencing Ischemic Stroke. The Prior Clearances In This Category Have Been Limited To Simply Identifying Catheter Placed In The Peripheral, Coronary, And Neurovasculature. It Is Felt That This Is A Unique Claim And Should Not Be Combined With Previously Cleared Catheters Under A General Procode.
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 Neurology devices follow this clearance model.
