Abstract
Described here are devices, methods, and systems for accessing and delivering devices to a heart. The left atrial appendage may be used as an access port to allow pericardial access to internal structures of the heart. Systems that may be used to provide access to the heart via the left atrial appendage may comprise a first access element with a first alignment member, a second access element with a second alignment member, a piercing element, and an exchange element. Some systems may further comprise a left atrial appendage stabilization device. Methods of accessing and delivering devices to the heart via the left atrial appendage may comprise advancing a first access element into the left atrial appendage by an intravascular pathway and advancing a second access element towards the left atrial appendage through the pericardial space. The first and second alignment members may form an attachment through the wall of the left atrial appendage so that the first and second access elements are aligned. A piercing element may be advanced to pierce the wall of the left atrial appendage to form an access site therethrough. Optionally, an exchange element may be advanced to initiate a trac…
