DISCOVER NEVA NET

THE NEXT FRONTIER IN THROMBECTOMY

THE FIRST AND ONLY CLOT MICRO-FILTRATION TECHNOLOGY

The NeVa NET devices incorporate a unique braided net on the inside of the distal end of the expandable tip.

“The new NeVa NET holds much promise and the fact the 4 mm version can be used with .021” microcatheters is wonderful. I believe that this new device will, in conjunction with other technologies such as large bore aspiration catheters and BGCs, offer the best chances of complete recanalization on first pass and better reperfusion for the brain. My initial experience has indeed been very good and this is effectively my go to device for M1 and ICA occlusions.”

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

ADDRESSING A COMMON YET
OVERLOOKED PROBLEM

Up to 40% of thrombectomies performed on ischemic stroke patients result in clot particles escaping to distal or new vascular territories, often causing adverse patient outcomes.

HOW TO PREVENT EMBOLIZATION Introducing NeVa NET™

Doctors Marc Ribo (Spain), Paul Bhogal (UK), and Daniel Behme (Germany) reveal their strategies for addressing this vexing clinical challenge in thrombectomy.

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.

Filter-tip SR achieved a non-significantly higher first-pass recanalization rate than open-tip SR and closed-tip SR. (66% vs 48% vs 44%; P=0.064)

Filter-tip SR was significantly better at preventing clot fragments >1mm from embolizing distal territories. (44% vs 16% vs 20%; P=0.003)

NeVa NET™ required less passes than Solitaire™ to achieve TICI 3 reperfusion (p=0.0344).
Solitaire™ generated 4-fold more clot fragments >1mm in size compared to NeVa Net™ (p=0.037, Wilcoxan rank sum).

BENCHTOP AND ANIMAL STUDIES
SHOW PROMISE

In experimental testing against the Solitaire™ device, NeVa NET obtained a higher rate of first-pass complete recanalization (100% vs. 60%, p=.0344) and generated 4-fold less clot fragments of larger than 1mm in size (p=.037, Wilcoxan rank sum) in the MCA territory.

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.

Learn more about the impact of this integrated filter from Vall d’Hebron Research Institute engineer Jiahui Li’s presentation at the BRAIN Meeting in December 2022, where she discloses the results of bench testing that compares the NeVa NET to two different stent retrievers.

PROF. DR. DANIEL BEHME

MAGDEBURG

“What we can’t do right now is control the area distal to the clot, even though that’s where we usually lose the emboli to. A microfiltration net is what we’re missing in stent retriever technology…based on the technology and the idea behind it, I think microfiltration can be a good way to reduce distal emboli.”

NEVA NET =
DROP ZONES +
MICROFILTRATION

Vesalio’s patented Drop Zone technology is proven to capture all clot types. The NET microfiltration reinforces NeVa’s capacity for retaining clot particles during the procedure, boosting physicians’ ability to achieve first pass success in recanalization and reperfusion of brain tissue for good patient outcomes.
