Abstract: Example devices and techniques are described herein for creating a multicuspid, multi-leaf interatrial shunt in the heart of a patient. An example device includes an elongate tool body and an inflatable balloon. The elongate tool body includes at least one lumen and a distal portion. The inflatable balloon is on the distal portion, and is configured to be inflated via the lumen. The inflatable balloon includes a distal outer surface configured for contacting an interatrial septum of a heart of a patient, and an ablation region of the distal outer surface of the inflatable balloon configured for ablating the interatrial septum when the inflatable balloon receives the ablation energy. The ablation region is disposed on the distal outer surface of the inflatable balloon in a manner that the ablation region creates a multicuspid ablation pattern when the inflatable balloon receives the ablation energy.
