Assessing Safety and Performance of the ANA Catheter System, Combined With a Stent Retriever in Acute Ischemic Stroke

Intra-arterial recanalization therapy or mechanical thrombectomy (MT) is a therapeutic option for patients who are not candidates for t-PA or in whom t-PA has failed. MT is performed by means of various devices (Merci Revive, Penumbra, etc.). There are currently two major approaches to MT: the so-called stent retrievers (used with or without a balloon catheter), and catheters used for direct aspiration (manual with syringe or by aspiration pump via distal access catheters \[DACs\]). Moreover, both techniques can be combined. MT may be performed following IV t-PA, as a stand alone therapy, or in conjunction with IA thrombolysis.
