Surpass Flow Diverter for Intracranial Aneurysms: SURMOUNT Registry Data Collection

Official Title

Prospective, Observational, Multi-Center, Single-Arm, Consecutive Enrollment, Post-Marketing, International Registry of the Surpass™ Flow Diverter in Intracranial Arteries

Brief Summary

      The purpose of this observational post-marketing registry will be to collect and analyze
      safety, effectiveness, and quality of life outcomes, during and after treatment with the
      Surpass Flow Diverter. Health Economics assessments (cost data) will also be collected and

Detailed Description

      This will be a prospective, observational, multi-center, single-arm, post-marketing,
      international registry with consecutive enrollment of a minimum of 150 patients treated with
      the Surpass Flow Diverter in accordance with the standard of care at up to 30 registry sites.

Study Type

Observational [Patient Registry]
