What is a Supera stent?

The Supera™ Peripheral Stent is indicated for the superficial femoral artery (SFA) and the proximal popliteal artery. Engineered by a unique interwoven wire technology, this nitinol stent offers physicians unmatched clinical outcomes5-16 across varied lesion complexities and lengths.

Is Supera stent bare metal?

The Supera peripheral stent system is a braided nickel–titanium alloy (nitinol) stent that was designed to withstand the unique stressors along the course of the femoropopliteal artery.

What is nitinol stent?

Nitinol stents are manufactured to a size slightly larger than the target vessel size and delivered constrained in a delivery system. After deployment, they position themselves against the vessel wall with a low, “chronic” outward force. They resist outside forces with a significantly higher radial resistive force.

What are Nitinol stents used for?

First-generation Nitinol stents were designed to provide sufficient scaffolding forces to hold open vessels, yet provide enough elasticity to “breathe” with pulsatile pressure differentials from the cardiac cycle. A variety of clinical studies indicate that these stents perform this primary function quite well.

What is Nitinol stent?

Why is Nitinol used for stents?

What characteristics of Nitinol make it an optimal material choice for stents?

Nitinol is able to handle these external forces better than other materials due to its characteristic properties of superelasticity and stress hysteresis. Due to kink resistance, these stents are well suited for the tortuous vessel pathways of peripheral arteries.

How do SES stents made from Nitinol work?

Nitinol stents are manufactured to a size slightly larger than the target vessel size and delivered constrained in a delivery system. After deployment they position themselves against the vessel wall with a low, chronic outward force. They resist outside forces with a significantly higher radial resistive force.
