Stroke treatment - NeVa NET

In NeVa NET™, Distal Embolic Filtration and Drop Zone™ technologies work together to enhance clot capture and retention, providing effective recanalization in ischemic stroke thrombectomy. The new NeVa NET 4.0 mm, following the success of the 5.5 mm version, is designed to offer clinicians an advanced tool for improving first-pass rates and reducing distal embolization.

Description
THE WORLD’S FIRST AND ONLY CLOT MICRO-FILTRATION TECHNOLOGY DESIGNED TO MAXIMIZE CLOT RETENTION

Building on the success of NeVa NET 5.5 mm in international markets, Vesalio has launched its NeVa NET 4.0 mm device to treat acute ischemic stroke due to large vessel occlusion. The introduction follows promising findings from studies published in the Journal of Vascular and Interventional Neurology and the Journal of NeuroInterventional Surgery.

Both the 5.5 mm and the newly launched 4.0 mm sizes incorporate NeVa NET’s integrated micro-filter, a unique, patented feature aimed at preventing the escape of clot particles into new or distal territories. Distal clot escape, observed in up to 40% of neuro-thrombectomy procedures, often negatively impacts patient outcomes by exacerbating the stroke event or causing future mini-strokes. Patented distal net filtration complements the NeVa™ device’s unique all-clots capability, enhancing clot retention capabilities.

HIGHER FIRST-PASS RATES, LOWER DISTAL EMBOLIZATION

Experimental benchtop testing against multiple stent retriever designs show promise of higher first pass rates and lower distal embolization.

DESIGNED TO MAXIMIZE CLOT RETENTION

This singular micro-filtration technology located inside NeVa’s closed distal tip, consists of 32 intricately braided nitinol strands of .00125”, effectively creating a filter with pore sizes of 385.3±68 μm.
