An atherectomy system for coring (10), ingesting and removing an obstruction material (12) from within a patient's vessel having a flexible guide-wire (140) defining voids for containing obstruction material and defining a diametrical envelope, a flexible rotary-catheter (21) slidable and rotatable over the diametrical envelope having a rotary coring means (22) at its distal end, a continuous passage defined around the flexible guide-wire by the flexible rotary-catheter for ingesting the cored obstruction material, and coupling means at the proximal end of the flexible rotary-catheter for coupling to rotating means. |
