A retrograde cannula for delivering fluid to a human heart has proximal and distal ends and includes an infusion lumen adapted to conduct CPG for discharge into the heart. An expandable balloon is disposed adjacent the distal end of the cannula for receiving CPG which expands the balloon into sealing relationship with a wall of the heart. A stylet lumen extends adjacent to the infusion lumen for receiving a stylet. A distal end of the stylet lumen is blocked. Alternatively, the stylet lumen can be eliminated, wherein the infusion lumen receives the stylet, but the inlet end of the infusion lumen has separate inlets, one being adapted to receive a stylus, and another being adapted to receive CPG.
