Renal ablation and visualization system and method with composite anatomical display image

A method and device that provide improved visualization of soft tissue, such as renal arteries, renal veins and lymph nodes in guiding catheter placement and positioning in the renal region or vasculature. The method and device enable visualization of an electrophysiology catheter application in the renal region which provides for improved imaging of renal structures, including renal arteries, along with one or more adjacent anatomical structures, including renal veins, lymph nodes, other adjacent organs and and/or other adjacent soft tissues that may adversely impact the formation of a lesion during a catheter ablation procedure in or around a renal artery.
