Figure 4: Mechanism of rupture. Diagrammatic illustration of rupture. (a) Position of micro-catheter inside the aneurysm before deployment. (b-f) Note the changes in the shape and position of the microcatheter as the coils are further loaded inside the aneurysm. This results in storage of potential energy and recoil of the microcatheter leading to rupture (f). Arrows indicate the changing axis of the micro-catheter during coiling
