Pipeline Flex Embolization Device

Aneurysm Flow Diversion


The clinically proven¹ Pipeline™ Flex device redefines treatment for large or giant wide-necked intracranial aneurysms by diverting flow away from the aneurysm neck, reconstructing the parent artery and restoring its natural course.2,3


The Pipeline Flex embolization device is indicated for the endovascular treatment of adults (22 years of age or older) with large or giant wide-necked intracranial aneurysms (IAs) in the internal carotid artery from the petrous to the superior hypophyseal segments.



The technical features of the Pipeline embolization device support a safe and highly effective procedure.2

  • 48-strand braided mesh design and a soft low profile distal tip4 for flexible conformability
  • 75% cobalt chromium / 25% platinum tungsten for radial force and uniform radiopacity
  • 30-35% surface coverage at nominal diameter⁵
  • Trackable through tortuosity, enabling better vessel deflection and allowing for a controlled distal landing zone4
  • Fully resheathable and can be repositioned and redeployed up to two times6

Clinical Outcomes*

The PUFs study was a multi-center, prospective, interventional, single-arm trial to evaluate the safety and effectiveness of the Pipeline implant in the treatment of complex intracranial aneurysms.

PUFs studied 108 patients with a wide-necked, large, or giant intracranial aneurysm in the petrous, cavernous, or paraophthalmic regions of the internal carotid artery.

  • 0% recurrence of aneurysms after complete occlusion¹
  • 0% major ipsilateral stroke or neurological death from 6 months to 5 years (5.6% M&M at 6 months)¹
  • 95% occlusion at 5 years follow-up¹
  • For treatment success, target aneurysm had to be 100%  occluded
