5. Study Description
Brief Summary
The primary objective of this clinical study is to determine whether the Innova Stent System shows acceptable performance in long-term (12-month) safety rates and vessel patency when treating femoropopliteal lesions.
Detailed Description
Atherosclerosis is a systemic disease that has become increasingly recognized in the expanding elderly population as a significant cause of morbidity and mortality. Atherosclerosis in the vessels of the lower extremities can cause a variety of symptoms ranging from intermittent claudication to ischemic rest pain and critical ischemia with major tissue loss. Typically, femoropopliteal lesions have been difficult to successfully treat with endovascular therapy because the disease is often diffuse and located in an area of the body subject to significant mobility stresses such as extension, contraction, compression, elongation, flexion and torsion.
The SuperNOVA clinical study is a prospective, single arm, controlled, multicenter, global study. Approximately 50 centers located in the United States, Europe, Canada and/or Australia are expected to participate in recruiting patients needing treatment of lesions in their femoropopliteal arteries. A maximum of 300 subjects will be enrolled to ensure that a minimum of 296 stented segments are treated with the Innova Stent System.

Walking Improvement Assessed by the Walking Impairment Questionnaire
Description
The Walking Impairment Questionnaire (WIQ) is a validated functional assessment questionnaire that evaluates walking ability with regard to speed, distance and stair climbing ability as well as the reasons that walking ability might be limited. Range of scores is between 0% and 100% with 100% being the best and 0% being the worst score.
Time Frame
12 months
Title

Assessment of walking improvement (time) by the administration of the 6 Minute Walk Test (6MWT). Participants were asked to walk for as long as they could; up to 6 minutes.
Time Frame
12 months
Title
Walking Improvement (Distance) Assessed by 6 Minute Hall Walk
Description
Assessment of walking improvement (distance) by the administration of the 6 Minute Walk Test (6MWT). Participants were asked to walk for as long as they could; up to 6 minutes.

Title
Quality of Life
Description
Improved Quality of Life assessed by the SF-36 Health Survey. The validated SF-36 Survey, where scores are calibrated so that 50 is the average score or norm, was utilized (scores ranging from 0, worst possible health to 100, best possible health). The SF-36 is a multipurpose, proprietary health survey with 36 questions that yield eight health component scales that can be further summarized into two summary scores: mental and physical health scores. The eight health component scales that can be computed from the questionnaire are physical function, role-physical, bodily pain, general health, vitality, role-emotional, mental health and social functioning.
