Aneurysm, Intracranial

To determine safety and effectiveness of the p48 MW HPC and p64 MW HPC Flow Modulation Device in the treatment of wide-necked intracranial aneurysms.

The objective of the Safety and Efficacy of Endovascular Treatment of Intracranial Aneurysms with Surpass Elite with GUARDian Flow Diverter (GUARD) trial is to evaluate the safety and efficacy of the Surpass Elite with Guardian Flow Diverter System (FDS) in the treatment of unruptured, wide-neck saccular or fusiform, intracranial aneurysms (IAs) located on the internal carotid artery (ICA) or its branches.

This study collected the clinical, laboratory, and imaging data from patients with intracranial aneurysms, who underwent Pipeline implantation. The purpose of this study is to observe the safety, effcacy, and haemodynamics after Pipeline embolization.
