Methods and systems for ablation mapping and ablation procedures are provided. In some embodiments, a catheter for visualizing ablated tissue comprises a catheter body; a support assembly extending past a distal end of the catheter body, the support assembly having a lumen therethrough; and a balloon having a proximal end and a distal end, wherein the proximal end of the balloon is attached to the catheter body and the distal end of the balloon is attached to the support assembly, the balloon having an opening at the distal end in alignment with the lumen of the support assembly to provide a continuous path from the catheter body to outside of the balloon. |
