The Study to Treat Superficial Femoral Artery Occlusions. - Full Text View

Purpose

The main objective of this study is to assess the performance of the Cordis SMART™ nitinol self-expandable stent for the treatment of superficial femoral artery (SFA) occlusions in comparison with balloon angioplasty only as determined by primary patency rate at one year.

Primary Outcome Measures:

Primary patency as demonstrated by duplex ultrasound. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Device success. [ Time Frame: at time of deployment ] [ Designated as safety issue: No ]
Procedural success: defined as successful recanalization, without the occurrence of a SAE event. [ Time Frame: up to the moment the catheter sheath introducer has been removed ] [ Designated as safety issue: Yes ]
Ankle Brachial Index [ Time Frame: at discharge and 12 months ] [ Designated as safety issue: Yes ]
Restenosis measured by Duplex Ultrasound [ Time Frame: at discharge and 12 months ] [ Designated as safety issue: Yes ]
Quality of Life assessment. [ Time Frame: at baseline, 3, 6, 9 and 12 months post procedure ] [ Designated as safety issue: No ]

Detailed Description:

This is a multi-center, prospective, randomized, two-arm study evaluating the performance of the Cordis SMART™ nitinol self-expanding stent as compared to angioplasty only.

It is anticipated that a total of 150 patients will be entered into the study. Patients will be randomized on a 1:1 basis of stent versus angioplasty only.

150 patients with de novo or restenotic native SFA occlusions (5-14.5 cm) with reference vessel of >= 4.0 to <= 6.0 mm in diameter will be randomized to the SMART™ nitinol self-expanding stent or to angioplasty only.

All patients will be followed for 12 months post-procedure, by telephone contact at 3, 6, 9 months and a 12 month clinical and duplex ultrasound assessment. This study will be conducted at up to 12 investigational sites.

Eligibility

Ages Eligible for Study:	30 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Symptomatic leg ischemia by Rutherford classification (category 1, 2, 3, 4 or 5); duration of intermittent claudication (category 1-3) should be at least 6 months.
One superficial femoral artery occlusion or re-occlusion with an occluded length > 5 to < 14.5 cm.

Exclusion Criteria:

Poor aortoiliac or common femoral "inflow", which would be deemed inadequate to support a femoropopliteal bypass graft.
Patient having total occlusions of the iliac artery on the same side must be excluded.
