Clinical Trial 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).

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.

6. Life expectancy >12 months.

Exclusion Criteria:

7. Women who do not have a negative serum or urine pregnancy test documented within 7 days prior to enrollment;

8. Any condition that precludes safe access with percutaneous transluminal angioplasty (PTA) devices, such as: excessive peripheral artery disease, unresolved fresh thrombus in the target lesion/vessel, or a target lesion/vessel that is excessively tortuous or calcified;

9. Lesions in contralateral SFA/PPA that require intervention during the index procedure, or within 30 days before or after the index procedure;

10. Previous treatment to the target lesion within the 3 months prior to enrollment; previous femoropopliteal bypass in target vessel; previous stenting of the target lesion;

11. Target lesion located within an aneurysm or associated with an aneurysm in the vessel segment either proximal or distal to the target lesion;

12. Target lesion requires treatment other than standard PTA prior to stent placement (i.e., no other devices or procedures such as cutting balloons and laser atherectomy are permitted to be used during the index procedure);

13. History of bleeding diatheses or coagulopathy or will refuse blood transfusions;

14. Known impaired renal function, defined as creatinine >2.5 mg/dl;

16. Known white blood cell (WBC) of <3,000 cells/mm3;

17. Participation in another investigational device or drug study and has not completed the primary endpoint(s) or which clinically interferes with the Complete SE SFA Study endpoints, or previously enrolled in the Complete SE SFA Study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Major Adverse Event (MAE) Rate	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.	12 Months	Yes
Primary	Primary Patency Rate	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).	12 Months	Yes
Secondary	Major Adverse Event (MAE) Rate	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.	30 days	Yes
Secondary	Major Adverse Event (MAE) Rate	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.	6 Months	Yes
Secondary	Device Success	The outcome is based on the angiographic evidence of <30% final residual stenosis of the target lesion using only the assigned device.	At time of deployment to the end of the treatment procedure (removal of vascular sheath from the patient).	Yes
Secondary	Lesion Success	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.	At time of deployment to the end of the treatment procedure (removal of vascular sheath from the patient).	Yes
Secondary	Procedure Success	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.	At time of deployment to time of hospital discharge	Yes
Secondary	Assisted Primary Patency	Defined as vessel patency resulting from a procedure performed in the treated segment.	12 months	Yes
Secondary	Secondary Patency Rate	Defined as vessel patency resulting from any procedure that restores patency.	12 Months	Yes
Secondary	Change in Quality of Life - Improvement in Rutherford Class by >= 1 Category	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.
