Summary: | An electrophysiology catheter is disclosed having a balloon with a membrane. Electrodes may be disposed on the membrane. Each electrode may include a radiopaque marker. The markers may have different forms, e.g., alphanumeric or polygonal, to facilitate visualization of the electrodes using a bi-stable image and allow for selection of the appropriate electrodes to be energized during ablation of tissue. The inventive subject matter allows for proper orientation of electrodes on the balloon under a two-dimensional imaging system. This allows the operator or physician to determine if certain electrodes are adjacent or contiguous to the posterior surface of the left atrium and ablate such posterior surface for shorter duration or at a lower power to create an effective transmural lesion on the posterior wall of the left atrium while reducing the chances of damaging the adjacent anatomical structures. |
