Summary

This study tested a device called the Orbital Atherectomy System in 81 Japanese adults with hardened blockages in their leg arteries (peripheral artery disease). The device grinds away calcium buildup to restore blood flow, avoiding more invasive procedures. The goal was to see if it is safe and effective for patients who are not good candidates for standard balloon treatment.
