摘要

An atherectomy system for removing an obstruction from within a patient's vessel, comprising a flexible guide wire (17) insertable into the vessel, a flexible rotary catheter (15) for coring and ingesting obstruction material, insertable into the vessel over the flexible guide wire, the flexible rotary catheter having a coring means (22) at its distal end and coupling means (30) for connecting it to a power source, at its proximal end, a sleeve (26) in which the flexible rotary catheter is slidably disposed, the sleeve having a window (35) near its open distal end.
