Designed to treat a range of aneurysm morphologies including unruptured wide-necked bifurcation and bifurcation aneurysms:

  • Provides a combination of flow diversion at the neck of the aneurysm and flow disruption within the aneurysm sac;
  • Supports neo-intimal growth across mesh at neck and subsequent thrombosis of aneurysm;
  • Deployed with proven existing clinical techniques;
  • A single device occlusion that is re-sheathable & re-deployable;
  • Electrolytic method of detachment;
  • Strong IP portfolio - 3 patents issued and 3 patents pending;
  • No intra-arterial stabilizing component;
  • Reduces/eliminates need for dual anti-platelet therapy;
  • Simplified sizing approach compared to other intra-saccular devices (i.e. neck  and widest diameter only).

How safe and effective are existing treatments for wide-necked bifurcation aneurysms?

Literature based objective performance criteria for safety and effectiveness 
Journal of Neurointerventional Surgery, October 11, 2017
Meta-Analysis, Fiorella et al.
Description: Outcome (1yr)
  • Wide Neck Bifurcation Aneurysm: 2,795
  • Complete Occlusion: 40%
  • Adequate Occlusion: 70%

Conclusion: Conventional therapies for WNBAs are associated with relatively low rates of complete occlusion and peri-procedural complications are not uncommon. Newer therapies are needed for the treatment of these aneurysms. Until a ‘gold standard’ treatment strategy is established, these emerging technologies can be evaluated in comparison to the benchmark literature-derived OPC presented*.
