Claim 0:
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 mitral valve device 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 prosthetic mitral valve device engages at least a portion of an upper annular surface within the left atrium without engaging a left ventricle of the patient's heart;
wherein the collapsed self-expanding prosthetic mitral valve device further comprises a proximal portion and a distal portion, wherein the prosthetic mitral valve leaflets are disposed within the distal portion;
loading an inner sheath into the delivery catheter lumen, the inner sheath having a distal end that engages the collapsed self-expanding prosthetic mitral valve device, wherein translation of the inner sheath through the delivery catheter lumen results in translation of the collapsed self-expanding prosthetic mitral valve device, which includes a one-chamber stented valve, through the delivery catheter lumen; and
wherein the inner sheath comprises a lumen therethrough sized to receive the proximal portion of the collapsed self-expanding prosthetic mitral valve device.
