Implantable medical endoprosthesis delivery systems and methods for making and using the same. An example implantable medical endoprosthesis delivery system may include an inner member having a first lumen disposed therein. An outer member may at least partially surround the inner member so that a second lumen is disposed between the inner and outer members. The second lumen may be configured so that an implantable medical endoprosthesis can be disposed therein. The delivery system may also include a hub including a fluid introduction port, a first fluid flow path in fluid communication with the fluid introduction port, and a second fluid flow path in fluid communication with the fluid introduction port.
