Contour - Neurovascular System
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 unruptured aneurysm sac.
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?
Journal of Neurointerventional Surgery, October 11, 2017
Meta-Analysis, Fiorella et al.
- 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*.
