Summary
This pilot study will investigate the safety, effectiveness and feasibility of the LimFlow Stent Graft System for creating an AV fistula in the Below The Knee (BTK) vascular system using an endovascular, minimally invasive approach for the treatment of Critical Limb Ischemia (CLI) in subjects ineligible for conventional endovascular or surgical limb salvage procedures.
