New Design for Enhanced Durability.
Proven in the Most Rigorous Studies Ever Conducted.
At Cook Medical, we're never satisfied. That's why we continue to improve and enhance a benchmark-setting product such as our Zilver stent. Zilver has been clinically shown to have one of the lowest fracture rates in the industry, but we wanted to make it better. Zilver Flex now improves the Zilver design by increasing the axial fatigue resistance to double that of leading industry competitors.* More flexible, more durable. Introducing the new Zilver, designed specifically to withstand the rigors of the SFA.

Finally a self-expandable stent approved for the iliac, superficial femoral artery (SFA) and above-the-knee popliteal artery, with one of the clinically proven lowest fracture rates.
Stable Deployment
Zilver Flex's linear cell stent design provides stable deployment by minimizing elongation and twisting that can lead to stent fractures.
Fracture Resistant Surface
Zilver Flex is painstakingly electropolished to Cook's industry-leading standards, eliminating the imperfections that can lead to stent fractures.
SFA Balanced Design
Zilver Flex is prospectively designed for the dynamic anatomy of the SFA, with an ideal balance of flexibility and strength that ensures maximum durability.
- Superior axial flexibility for the compression that occurs during hip flexion and knee bending.
- Superior torsional flexibility for the twisting forces present in the SFA.
- Tight bending radius greatly reduces the likelihood of stent kinking in the SFA.

Proven Durability
The durability of the Zilver Flex design is being PROVEN through:
- The largest level 1 randomized SFA study (data to be reported in early 2010).
- The most exhaustive level 2a SFA registry study ever conducted. Interim results show the following through at least one-year follow-up.
