Vascular Self-Expanding Stent System

Laser-cut Nitinol stent purpose-built for the SFA with flexibility, strength and fracture resistance


Flexibility is important because the SFA has strong and  complex mechanical movements. An SFA stent must have the ability to track through tortuous, dynamic anatomy and conform to the vessel.
The Innova Stent was  engineered for flexibility with an open cell design along the stent body.

The offset strut peaks (peak-to-valley design) enhances conformability, axial flexibility and kink resistance.


The Innova Stent provides strength necessary to stay open within the challenging and dynamic SFA. Outward radial force allows the stent to fully open, while strong compression resistance enables the stent to maintain lumen diameter even during vessel movement and external pressure. 

The Innova Stent architecture was designed to provide these properties. Strut width, length, and thickness dimensions optimize outward radial force and compression resistance. Additionally, the exact spacing of connectors provides balanced stress distribution and strength.

Fracture Resistance

The SFA is subject to unique mechanical forces like compression and bending, which cause fatigue fractures in stents.1

The Innova Stent is designed to withstand multiple deformation modes including elongation, extreme bending and axial compression, through a balanced spacing of strut connectors.

Custom materials and processing practices, including high purity Nitinol and enhanced stent polishing, create excellent fatigue resistance for the Innova Stent.
