Method of guidewire insertion

摘要

An atherectomy system for coring, ingesting and removing plaque from within a patient's vessel having a flexible guide wire defining a void for holding plaque during the atherectomy process and for accurately guiding a flexible catheter in the vessel. Coupling means at the proximal end of the flexible catheter for coupling it to drive means. The insertion of the guidewire may be assisted by suspending a body part in a decompression chamber to dilate the vessel.
