Abstract: A rapid exchange stent delivery catheter includes an inner tubular member having a proximal portion, a distal portion, a stent holding portion located adjacent the distal portion of the inner member, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal portion of the inner member to a distal guide wire opening disposed at a distal end of the inner member. The proximal guide wire opening has a first length. An outer tubular member is slidably disposed about the inner member. The outer member has a proximal portion, a distal portion, and a guide wire opening disposed distal of the proximal portion of the outer member. The guide wire opening of the outer member has a second length that is shorter than the first length and a guide wire ramp extends into, and is movable along the first length.
