SAFETY IN NUMBERS

The Pipeline™ Flex embolization device (Pipeline™ Flex) provides reliable safety across multiple aneurysm types.1,4,5

Primary safety endpoint results at 1 year:

  • PREMIER Study4 — 2.1% 
  • PUFs Study1,5 — 5.6%

PREMIER: The primary safety endpoint was incidence of major stroke (ischemic or hemorrhagic) in the territory supplied by the treated artery (defined as an increase of 4 points on the National Institute of Health Stroke Scale (NIHSS)) or neurologic death within 1 year after treatment.

PUFs: The primary safety endpoint of the PUFS study was the incidence of major ipsilateral stroke (defined as an increase of ≥4 points on the NIHSS and present after 7 days as adjudicated by the Clinical Events Committee) or neurological death within 180 days of Pipeline™ embolization device placement.

TIME-TESTED EFFICACY

Pipeline™ Flex achieves reliable efficacy across multiple aneurysm types at 1 year5 and out to 5 years.1,6*

Primary effectiveness endpoint results at 1 year:

  • PREMIER Study4 — 76.8% 

Long term complete occlusion rates:

  • PUFs Study1,5 — 95%  at 5 years with 0% recurrence

PREMIER: The primary effectiveness endpoint of the study was complete aneurysm occlusion of the target aneurysm without major stenosis (≤ 50%) of the parent artery or retreatment of the target aneurysm at one year post-procedure, as adjudicated by an independent core laboratory (“Core Lab”), or retreatment of the target intracranial aneurysms (IA) one year post-procedure.

PUFs: The primary effectiveness endpoint of the study was complete occlusion of the aneurysm without major (>50%) stenosis of the parent artery or adjunctive use of complimentary embolic agent as seen on 180-day angiography and judged by the independent core research lab (CRL).

TRUSTED POSITIONING

The design and material properties of Pipeline™ Flex lead to uniform wall apposition.7 When delivered through the Phenom™ 27 catheter, specifically designed for flow diversion,8 system stability is optimized.9

PIPELINE™ FLEX TECHNICAL FEATURES

The technical features of Pipeline™ Flex support a safe and highly effective procedure.2

  • 48-strand braided mesh design and a soft low profile distal tip10 for flexible conformability
  • 75% cobalt chromium / 25% platinum tungsten for radial force and uniform radiopacity11
  • 30-35% surface coverage at nominal diameter12
  • Trackable through tortuosity, enabling better vessel deflection and allowing for a controlled distal landing zone10
  • Fully resheathable and can be repositioned and redeployed up to two times10

INDICATIONS FOR USE6

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

The Pipeline Flex embolization device is also indicated for use in the internal carotid artery up to the terminus for the endovascular treatment of adults (22 years of age or older) with small and medium wide-necked (neck width ≥ 4 mm or dome-to-neck ratio < 2) saccular or fusiform intracranial aneurysm (IAs) arising from a parent vessel with a diameter ≥ 2.0 mm and ≤ 5.0 mm.

CAUTION: Federal (USA) law restricts this device to sale distribution and use by or on order of a physician. Indications, contraindications, warnings and instructions for use can be found in the product labeling supplied with each device.
