Prosthetic mitral valve device

The invention relates to a prosthetic mitral valve device. More specifically, methods, systems, and devices are disclosed to deliver a self-expanding prosthetic mitral valve device to the left atrium, without engaging the left ventricle, native mitral valve leaflets, or annular tissue downstream of the upper annular surface during delivery, and in some embodiments, the left ventricle, native mitral valve leaflets, or annular tissue downstream of the upper annular surface. The ventricle, mitral valve leaflets, and/or annular tissue downstream of the upper annular surface are not engaged by the delivered, positioned, and expanded prosthetic mitral valve device. 本发明涉及假体二尖瓣膜装置。更具体而言，公开了方法、系统和装置来将自扩张假体二尖瓣膜装置输送到左心房，在输送期间不接合左心室、原生二尖瓣膜小叶或上环形表面下游的环形组织，并且在一些实施例中，心室、二尖瓣膜小叶和/或位于上环形表面下游的环形组织不被已输送、已定位并且已扩张的假体二尖瓣膜装置接合。
