Study Description

Brief Summary:

To evaluate the safety and efficacy of the Complete SE SFA Stent System in the treatment of de novo and/or restenotic lesions or occlusions in the Superficial Femoral Artery (SFA) and/or Proximal Popliteal Artery (PPA) in subjects with symptomatic Peripheral Artery Disease (PAD).

Condition or disease	Intervention/treatment	Phase
Peripheral Vascular Disease	Device: Complete SE Vascular Stent System	Not Applicable

Detailed Description:

The Complete Self-Expanding (SE) SFA Stent is designed to be a permanent implant. It is cut from a nickel titanium alloy (Nitinol) tube and consists of a series of segments each connected to the next in a unique pattern to allow for flexibility and vessel conformability. Each segment consists of two struts and a crown (Figure 1). It is designed to produce optimal luminal diameter and increased scaffolding, and to maintain luminal patency.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Complete SE Vascular Stent System; COMPLETE SE Vascular Stent System - implantation of study device in native SFA and/or PPA for subjects with symptomatic ischemic peripheral arterial disease in the superficial femoral artery or proximal popliteal arteries with an occlusion or lesion greater or equal to 50 percent with lesions located above the knee and amenable to percutaneous treatment with angioplasty and vascular stent implantation.

Device: Complete SE Vascular Stent System; Complete SE Vascular Stent System in the treatment of de novo and/or restenotic lesions or occlusions in the Superficial Femoral Artery (SFA) and/or the Proximal Popliteal Artery (PPA) in subjects with symptomatic Peripheral Artery Disease (PAD).

Outcome Measures

Primary Outcome Measures :

1. Major Adverse Event (MAE) Rate [ Time Frame: 12 Months ]
   Major Adverse Events (MAE) defined as device and/or procedure related death (or any death occurring post-procedure through Day 30), target limb loss and target lesion or target vessel revascularization.
2. Primary Patency Rate [ Time Frame: 12 Months ]
   Primary patency defined as uninterrupted patency with no procedures performed on or at the margins of the treated segment, with no restenosis ≥ 50% as documented by peak systolic velocity ratio ≥2.0 as assessed by duplex ultrasound (DUS).

Secondary Outcome Measures :

1. Major Adverse Event (MAE) Rate [ Time Frame: 30 days ]
   Major Adverse Events (MAE) defined as device and/or procedure related death (or any death occurring post-procedure through Day 30), target limb loss and target lesion or target vessel revascularization at the 30 day timepoint.
2. Major Adverse Event (MAE) Rate [ Time Frame: 6 Months ]
   Major Adverse Events (MAE) defined as device and/or procedure related death (or any death occurring post-procedure through Day 30), target limb loss and target lesion or target vessel revascularization at the 6 month timepoint.
3. Device Success [ Time Frame: At time of deployment to the end of the treatment procedure (removal of vascular sheath from the patient). ]
   The outcome is based on the angiographic evidence of <30% final residual stenosis of the target lesion using only the assigned device.
4. Lesion Success [ Time Frame: At time of deployment to the end of the treatment procedure (removal of vascular sheath from the patient). ]
   The outcome is based on the angiographic evidence of <30% final residual stenosis of the target lesion using either the Complete SE SFA Stent System or other standard percutaneous devices.
5. Procedure Success [ Time Frame: At time of deployment to time of hospital discharge ]
   The outcome is based on the angiographic evidence of <30% final residual stenosis of the target lesion after stent implantation and no occurrence of a procedure-related Major Adverse Events (MAE) prior to hospital discharge.
6. Assisted Primary Patency [ Time Frame: 12 months ]
   Defined as vessel patency resulting from a procedure performed in the treated segment.
7. Secondary Patency Rate [ Time Frame: 12 Months ]
   Defined as vessel patency resulting from any procedure that restores patency.
8. Change in Quality of Life - Improvement in Rutherford Class by >= 1 Category [ Time Frame: 12 months ]
   Improvement in Rutherford class by ≥ 1 category increase at 12 months from pre-procedure according to the Rutherford Scale Classification. The Rutherford Classification is a categorical scale (0 - 6) used by clinicians to assess the degree of peripheral arterial disease in a person. The scale begins with 0 (no symptoms) and ends with 6 (worse case symptoms).
9. Change in Quality of Life - Increase in Ankle-brachial Index (ABI) or Toe-brachial Index (TBI) >= 0.15 [ Time Frame: 12 Months ]
   Increase in ABI/TBI ≥ 0.15 at 12 months from pre-procedure. An increase in ABI/TBI of 0.15 or greater is considered by clinicians to be a significant improvement.
10. Change in Quality of Life - Decrease in Rutherford Class >= 1 Category [ Time Frame: 30 Days ]
    Decline in Rutherford class ≥ 1 category at 30 days when compared to pre-procedure according to the Rutherford Scale Classification. The Rutherford Classification is a categorical scale (0 - 6) used by clinicians to assess the degree of peripheral arterial disease in a person. The scale begins with 0 (no symptoms) and ends with 6 (worse case symptoms).
11. Percentage of Participants Free From Strut Fractures [ Time Frame: 12 Months ]
    Defined as percent free from strut fractures. Percentage based on number of stents implanted with flat plate x-ray follow-up.
12. Clinically-driven Target Lesion Revascularization (TLR) Rate [ Time Frame: 12 Months ]
    Defined as those revascularizations in which the subject has ischemic symptoms consistent with changes within the target lesion as demonstrated by: a change (decrease from post-procedure) in the Rutherford scale by at least one category, or a change (decrease from post-procedure) in ABI/TBI >= 0.15
13. Major Adverse Event (MAE) Rate [ Time Frame: 24 Months ]
    Major Adverse Events (MAE) defined as device and/or procedure related death (or any death occurring post-procedure through Day 30), target limb loss and target lesion or target vessel revascularization at the 24 month timepoint.
14. Percentage of Participants Free From Strut Fractures [ Time Frame: 24 Months ]
    Defined as percent free from strut fractures. Percentage based on number of stents implanted with flat plate x-ray follow-up at the 24 month timepoint.
15. Major Adverse Event (MAE) Rate [ Time Frame: 36 Months ]
    Major Adverse Events (MAE) defined as device and/or procedure related death (or any death occurring post-procedure through Day 30), target limb loss and target lesion or target vessel revascularization at the 36 month timepoint.
16. Percentage of Participants Free From Strut Fractures [ Time Frame: 36 Months ]
    Defined as percent free from strut fractures. Percentage based on number of stents implanted with flat plate x-ray follow-up at the 36 month timepoint.
