Purpose
The purpose of this study is to evaluate the safety and performance of the Xpert(TM) self-expanding stent in infrapopliteal lesions as part of an overall treatment strategy in patients undergoing percutaneous intervention for the treatment of documented chronic critical limb ischemia (CLI).

| Study Design: | Intervention Model: Single Group Assignment Masking: Open Label Primary Purpose: Treatment |
| Official Title: | Phase 1 Study of Xpert(TM) Nitinol Stenting for Critically Ischemic Lower Limbs |
- Amputation free survival at 12 months in the target limb. Amputation for the primary endpoint is defined as a major, unplanned, amputation of the target limb through the 12 month visit where prosthesis is required for standing or walking. [ Time Frame: 1 year ]
- Assess improvement in wound healing; assess restenosis; measure target lesion revascularization to maintain patency at 12 months; measure ankle/brachial improvement level; assess stent integrity; characterize improvement in health related quality of life [ Time Frame: 2 years ]

Peripheral arterial disease (PAD) of the lower extremities affects roughly 25 million Americans annually. The diabetic population is particularly prone to the most severe clinical problems associated with PAD and the amputation rate amongst such patients is elevated five-fold. It has been shown that patients who undergo amputation for PAD/CLI have a much higher mortality rate in the months that follow.
Despite medical advances in the fields of pharmacology and wound care, the vast majority of patients who present with CLI will ultimately require amputation in the absence of improved blood flow. Recently, much attention has been directed towards less invasive endovascular solutions for treating patients with CLI. This study will evaluate approximately 140 subjects with Rutherford Class IV-VI PAD in a multi-center study in order to accurately estimate limb salvage rates for this treatment.
