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. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Neurology devices follow this clearance model.
