Abstract
Systems, devices, and methods for electroporation ablation therapy are disclosed in the context of esophageal ablation. An ablation device may include a first catheter defining a longitudinal axis and a lumen therethrough. A balloon may be coupled to the first catheter. The balloon may be configured to transition between a deflated configuration and an inflated configuration. A second catheter may extend from a distal end of the first catheter lumen. A set of splines including electrodes formed on a surface of each of the splines may couple to the distal end of the first catheter lumen and a distal portion of the second catheter. The second catheter may be configured for translation along the longitudinal axis to transition the set of splines between a first configuration and a second configuration.
