Primary Outcome Measures :
  1. Change in the rate of complete occlusion [ Time Frame: immediately after treatment, an expected average of 1 hour; to 12 months ]
    Rate of complete aneurysm occlusion is assessed immediately after treatment (an expected average of 1 hour) and at both follow-up visits (3-6 months and 7-12 months). The change is assesed.

  2. Change of frequency of major stroke (ischemic or hemorrhagic) or neurological death related to the treatment of the target aneurysm [ Time Frame: immediately after treatment, an expected average of 1 hour; to 12 months ]
    Frequency of major stroke (ischemic or hemorrhagic) or neurological death is assessed immediately after treatment (an expected average of 1 hour) and at both follow-up visits (3-6 months and 7-12 months). The change is assesed.


Secondary Outcome Measures :
  1. Intra-procedural technical complications [ Time Frame: during treatment, an expected average of 1 hour ]
    p64 placed in the desired location Correct opening of p64 (markers fully deployed) at the end of the procedure Ability to detach p64 at the end of the procedure

  2. Change of Angiographic results [ Time Frame: immediately after treatment, an expected average of 1 hour; to 12 months ]
    Change in both Rate of re-growth (related rate of re-treatment) and Rate of recanalization (related rate of re-treatment) are assessed immediately after treatment (an expected average of 1 hour) and at both follow-up visits (3-6 months and 7-12 months).

  3. Intra-procedural vascular complications [ Time Frame: during treatment, an expected average of 1 hour ]
    Vessel perforation (e.g. with distal wire tip of p64, microcatheter) Target aneurysm perforation (e.g. with distal wire tip of p64, microcatheter) Thromboembolism Dissection of any access vessel Side branch occlusion

  4. Post-procedural Complications [ Time Frame: 3-6 and 7-12 months ]
    Parenchymal hemorrhage detected during the follow-up period Subarachnoid hemorrhage detected during the follow-up period Ischemic stroke detected on follow-up imaging Rupture of the target aneurysm detected during the follow-up period Rate of in-stent-stenosis detected during the follow-up period
