Inari Medical, Inc. announced U.S. Food and Drug Administration (FDA) 510(k) clearance of the FlowTriever system for the treatment of clot in transit (CIT) in the right atrium. CIT is a life-threatening condition which occurs when a deep vein thrombosis (“DVT”) breaks loose and embolizes to the right heart. 25,000 patients are diagnosed with right atrial CIT in the United States annually, and the condition is associated with a mortality rate of over 80% if left untreated. FlowTriever is the first thrombectomy system not requiring a cardiopulmonary bypass circuit to be FDA cleared for blood clots in the right atrium.
