EverFlex™ Self-expanding Peripheral Stent System

The EverFlex stent is deliverable through a 6 F catheter. The spiral-cell connection and peak-to-peak connection nodes are designed to disperse force uniformly, while the three-wave peak design resists compression and provides excellent wall apposition. The EverFlex stent also has a flexible stent design that improves fracture resistance and restores vessel patency. In addition, the broad size matrix (20 mm – 200 mm) allows physicians to choose the most appropriate single-stent fit.


DURABILITY II1 is the first controlled study to focus on treating long, complex lesions and to specifically test the performance of a single long stent in the superficial femoral artery.

The study enrolled 287 patients:
  • The mean stenosed lesion length was 89.1 mm
  • 70.0% of patients had moderate to severe calcification
  • 48.1% of lesions were totally occluded
  • 73.0% of patients received stents > 100 mm
  • 95% of patients received a single stent

Three years later, the results continue to offer evidence that even in long, complex lesions, the EverFlex stent is able to sustain patency and durability.

DURABILITY Iliac3 was conducted to confirm the safety and effectiveness of primary stenting using the EverFlex™ and Protégé™ GPS™ Self-expanding stent systems for the treatment of lesions in the common and external iliac arteries. Noteworthy points about the study:

  • 75 subjects enrolled
  • ≥ 50% stenosis, restenosis or occlusion
  • Target lesion length ≤ 10 cm
  • Target vessel diameter is ≥ 4.5 mm and ≤ 11.0 mm
Results of DURABILITY Iliac study with EverFlex Stent
  • 31/75 patients enrolled in the study received an EverFlex stent
  • No major adverse events at nine months
    • 0% clinically drive TLR
    • 0% periprocedural death
    • 0% in-hospital MI
    • 0% amputation of treated limb
  • Nine-month primary patency rate of 93.2%
