Systems, methods and devices for delivery systems, methods and devices for implanting prosthetic heart valves
First Claim
1. A method of delivering a self-expanding prosthetic mitral valve device comprising prosthetic mitral valve leaflets to an implantation site within a left atrium of a patient'"'"'s heart, comprising:
- accessing the left atrium with a delivery catheter having a proximal end, a distal end and a lumen therethrough;
loading the self-expanding prosthetic mitral valve device in a collapsed configuration into the lumen of the delivery catheter at the proximal end thereof, wherein the collapsed configuration of the prosthetic mitral valve device comprises a prosthetic mitral valve attached thereto;
delivering the collapsed prosthetic valve out of the distal end of the delivery catheter and into the left atrium at a location proximate the implantation site;
allowing the delivered self-expanding prosthetic mitral valve device to expand within the left atrium at the implantation site, wherein at least a portion of the expanded device engages at least a portion of the upper annular surface within the left atrium; and
ensuring that the left ventricle, the annular tissue below or downstream of the upper annular surface and the native mitral valve leaflets of the heart are not touched at any point in the delivery of the self-expanding prosthetic mitral valve device before the delivered self-expanding prosthetic mitral valve device is allowed to expand within the left atrium;
providing a plug attached directly to a side portion of the collapsed self-expanding prosthetic mitral valve device;
aligning the plug with the left atrial appendage; and
engaging the left atrial appendage with the plug when the self-expanding prosthetic mitral valve device is expanded.

Abstract
Embodiments of delivery systems, devices and methods for delivering a prosthetic heart valve device to a heart chamber for expanded implementation are disclosed. More specifically, methods, systems and devices are disclosed for delivering a self-expanding prosthetic mitral valve device to the left atrium, with no engagement of the left ventricle, the native mitral valve leaflets or the annular tissue downstream of the upper annular surface during delivery, and in some embodiments with no engagement of the ventricle, mitral valve leaflets and/or annular tissue located downstream of the upper annular surface by the delivered, positioned and expanded prosthetic mitral valve device.
