Abstract:
1. A system for performing an ablation procedure on a heart of a patient, the system comprising: a visualization device having a distal end, the visualization device comprising; an ablation device for ablating a portion of the heart, the ablation device at least partially disposed in the lumen of the visualization device, wherein a distal end of the ablation device extends distally beyond the visualization device distal end; and a heart positioning device for moving the heart into a desired position, the heart positioning device comprising an elongate shaft defining a proximal end and a distal end, and an inflatable positioning member coupled with the shaft at or near the distal end; wherein the at least one balloon comprises a first balloon disposed around a circumference of the visualization device such that when the first balloon is inflated the distal end of the elongate visualization member is recessed proximal to a distal end of the first balloon, and wherein the inflated first balloon creates a space between a pericardial layer around a heart and an outer surface of the heart.
