20. A method for accessing a coronary artery, the method comprising:
-
providing a guide catheter; advancing the guide catheter through a blood vessel to a position adjacent to an ostium of a coronary artery; providing a guide extension catheter, the guide extension catheter including; a proximal member having a proximal outer diameter, a removable stiffening member disposed adjacent to the proximal member, and a distal sheath member attached to the proximal member, the distal sheath member having a distal outer diameter greater than the proximal outer diameter; advancing the guide extension catheter through the guide catheter to a position where at least a portion of the distal sheath member extends distally beyond a distal end of the guide catheter and into the coronary artery; removing the stiffening member from the proximal member; and advancing a treatment catheter through the guide catheter.
