A sterile, battery–powered wire with a rotational cutting tip intended to be percutaneously placed into the peripheral vasculature (not heart or central nervous system) to create a pathway through a chronic vascular obstruction [e.g., a chronic total occlusion (CTO)], and to function as a guide for the introduction of another device (e.g., manual guidewire, catheter). It consists of a long, thin, shapeable/steerable wire and a detachable battery-powered motor/control unit; it is typically used under fluoroscopic guidance. This is a single-use device.
