The primary objective of the TORUS 2 IDE Clinical Study is to evaluate the safety and effectiveness of the TORUS Stent Graft System in the treatment of obstructive atherosclerotic lesions of the native SFA or the superficial femoral and/or proximal popliteal arteries.

The TORUS Stent Graft is an intravascular prosthesis intended to improve blood flow in the area in which it is implanted and the TORUS Stent Graft Delivery System is a standard pin-and-pull delivery system used to implant the SG in the desired area. Use of the TORUS Stent Graft allows for improving blood flow in the peripheral vasculature.
Freedom from a Major Adverse Event (MAE)
An MAE is defined as all-cause death, target limb major amputation and clinically-driven target lesion revascularization (CD-TLR)
Time frame: 30 days
Primary Patency
Primary patency is defined as the absence of clinically-driven target lesion revascularization (CD-TLR) and absence of recurrent target lesion diameter stenosis \>50% by duplex ultrasound with a peak systolic velocity ratio of \>2.5.
Time frame: 12 months
Technical Success
Technical success is defined as the ability to cross and dilate the lesion to achieve residual stenosis of ≤30%
Time frame: At the time of the index procedure
Procedural Success
Procedural Success is defined as technical success with out any MAEs.
Time frame: Within 24 hours of the procedure
Major Adverse Event (MAE) Rate
Composite rate of all-cause death, target limb major amputation and clinically-driven target lesion revascularization (CD-TLR).
Time frame: 12 months
Patency Rate
Absence of CD-TLR and absence of recurrent target lesion diameter stenosis \>50% by duplex ultrasound with a peak systolic velocity ratio of \>2.5.
Time frame: Through 36 months
Assisted Primary Patency Rate
Revascularization of non-occlusive (\<99%) stenosis within the stent graft or immediately above or below the treated arterial segment (end of the graft and 1cm of artery beyond) with less than 50% residual stenosis.
