Apparatus and method for capturing a wire in a blood vessel

摘要

An apparatus (600) for capturing a wire within a lumen of a blood vessel comprises a tube (602) having a proximal end (604) and a distal end (606). The distal end (606) of the tube (602) is adapted for placement within a lumen of a blood vessel. A wire loop (632) extends from the distal end (606) of the tube (602), the wire loop (632) has a substantially cardioidal shape. The apparatus (600) further includes means (614) for constricting the wire loop (632).
