Abstract
Described here are devices 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. 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 track between the inside and outside of the left atrial appendage, which may be used for device delivery. Some systems may further comprise a left atrial appendage stabilization device.
