Abstract
Abstract A TMR energy delivery device is introduced through a first minimally invasive penetration of a patient's chest. Sufficient energy if delivered from the wave guide to the wall of the heart to form a channel through at least a portion of the wall. The device includes a visualization device or camera with a rigid portion and a distal end portion that is flexible, a cup member coupled to a distal end of the flexible distal portion, and a vacuum source coupled to the cup member for providing mechanical stability against the heart wall.
