Abstract
Disclosed are devices for pericardial access to the heart, including direct access to the left atrium. In certain embodiments, the device may comprise a device and/or an atrial appendage (AA) portal having a configuration such that the distal end of the device and/or the portal can access an atrial appendage while the proximal end of the device and/or portal can extend to outside of the subject. The devices and methods may also include a pericardial portal for emplacement of the device and/or the AA portal. Also, methods for using such devices and/or AA portals and pericardial portals to perform surgery on the heart, and systems (e.g., kits) comprising these devices and/or portals in combination with other therapeutic devices are disclosed.
