Multi-center, feasibility study treating up to 20 atherosclerotic lesions in the infrapopliteal arteries. The study will capture angiographic imaging (pre, during, post, and post 15 mins) for all lesions, and a subset (up to 10) of IVUS imaging data (pre, post, and post 15 mins), to compare serration angioplasty vs standard angioplasty and its effects on vessel recoil and final diameter stenosis.
The study objective is to assess the ability to define and measure post treatment recoil in infrapopliteal arteries. Preliminary evidence as to the differences between serration angioplasty and standard balloon angioplasty as defined by post treatment recoil, lumen gain, and dissection will be collected.
