Abstract
The invention describes a method of treating a patient's left atrial appendage through the pericardial space. The process takes place through the pericardial space from an access point outside the pericardium or pericardial space.
Claims9
A method for treating the atria appendage comprising:
- entering the chest cavity with a surgical instrument creating a surgical opening;
- introducing a pericardial access device through said opening;
- entering the pericardial space between the pericardium and the heart;
- navigating an electrosurgery device to the atrial appendage;
- activating the electrosurgical device to remodel the atrial appendage.

The method of claim 2 wherein said navigating step is carried out under visual guidance through the endoscopic system.
The method of shrinking the atrial appendage comprising the steps:
- entering the chest cavity with a surgical instrument creating a surgical opening;
- introducing a pericardial access device through said opening of the type having an extended catheter body with an aspiration lumen for connecting to the pericardium;
- entering the pericardial space between the pericardium and the heart;
- navigating an electrosurgery device of the type having at east one saline electrode, to the atrial appendage;
- activating the electrosurgical device while irrigating the artrial appendage with saline from the electrosurgery device, to remodel the atrial appendage.
