Cerus_Contour_Hero_03 Horiz wBackg.jpg

Targets the neck of the aneurysm

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*. 

What does it take to be a “big believer” in intrasaccular devices?


Tufail Patankar (UK) speaks about his personal experience with these effective tools, during the LINNC, Paris 2019 Congress.
