Abstract
An ablation system, configured to create a shunt between a left atrium and a coronary sinus of a patient, includes an ablation device comprising a proximal body defining a distal-facing surface configured to contact the coronary sinus wall, a distal body defining a proximal-facing surface positioned opposite the distal-facing surface and configured to contact the left atrium wall, and first and second heating elements disposed on the distal-facing and proximal-facing surfaces, respectively. The heating elements are configured to ablate tissue between the left atrium and the coronary sinus of the patient to create the shunt. The system further includes an expandable dilation element configured to dilate a puncture formed through the coronary sinus wall and the left atrium wall to facilitate introduction of the distal body of the ablation device into the left atrium.
