News & Announcements

  • June 2026

    Packed house at LINNC online Paris!
    Incredibly proud to see Dr. Raphael Blanc take the stage to a full auditorium, sharing his exceptional early clinical experience with the Viva™ Stent.
    The strong turnout and deep engagement from the neuro-interventional community underscore the vital need for on label and safe venous stents.
    A huge thank you to Dr. Blanc and the brilliant team at Fondation Adolphe de Rothschild for their pioneering work and dedication to advancing patient care.

    First Viva stent case in Europe

    Case Highlight: Precision in Venous Stenting

    “After using the Viva stent for the treatment of transverse sinus stenosis, what stood out to me most was how access, control, and precision come together as a single continuum. Navigating the jugular bulb smoothly over a 0.014″ wire—without the need for an intermediate catheter—immediately simplified what is often the most challenging step.
    From there, the combination of excellent trackability and full resheathability enabled precise positioning, with the confidence to reposition when needed. Overall, a procedure that is typically technically demanding became more straightforward, controlled, and predictable.”
    Dr. Raphael Blanc

Breakthrough Treatment Cures Chronic Headaches And Tinnitus

Adel Gitman spent two years plagued by tinnitus. “Imagine walking around with a whooshing sound every minute, every second, of your life. There is no break, no rest, no silence,” she explains. “I would walk on the beach, unable to hear the waves. Every slight effort, each movement of the head—the noise in my left ear got louder. I couldn’t sleep.”
