Complex curve microcatheters for berry aneurysm endovascular therapy.

By using images created with 3D rotational angiography or CT angiography as templates, it is possible to place anatomically correct curves on microcatheters, curves that reproduce the complex 3D vascular anatomy of individual patients. Catheters so curved conform to the anatomy of arteries leading to aneurysms and are less likely to be forced out of position as coil packing progresses.
