Figure 2: The embolization process by using the photocurable agents in a glass aneurysms model. (a, b) A glass aneurysm model with parent artery (ID: 3 mm) and aneurismal sac (ID: 5 mm). The working fluid was 0.9% saline (pulsatile flow: 14 bpm, flow rate: 98 mL/min). A 6 Fr-delivery catheter was navigated to the neck of the aneurysmal sac. (c, d) The photocurable agent was delivered into the sac through the catherter under the inflation of a balloon catheter at the neck. (e) The inside of the sac was filled with the agent. (f) The light was irradiated to the agent from the neck side after removing the delivery catherter. (g) The balloon catherter was removed. (h) The flow of the green-colored solution was uniformly distributed only at the parent tube without inflow into the sac.
