Abstract
Systems, devices, and methods for electroporation ablation therapy are disclosed herein, including an inflatable member for positioning an ablation device within a pulmonary vein ostium. An apparatus can include first and second shafts moveable relative to one another, first and second electrodes configured to generate an electric field for ablating tissue, and an inflatable member disposed between the first and second electrodes. In some embodiments, the inflatable member is configured to transition from an undeployed configuration to a deployed configuration in response to movement of the first and second shafts. In some embodiments, the inflatable member in the deployed configuration can engage a wall of a pulmonary vein ostium and direct the electric field generated by the first and second electrodes toward the wall.
