摘要：
A prosthetic valve delivery system, the system comprising a sequentially deployable prosthetic heart valve and an external sheath to restrict the valve； said valve comprising: a self-expanding shell (600； 700； 800； 900) having a first end, a second end opposite the first end, an atrial region (606； 706； 806； 906) near the second end and a region ventricular (610) .； 710； 810； 910) near the first end, in which the self-expanding frame (600； 700； 800； 900) has an expanded configuration and a folded configuration, the expanded configuration that is adapted to engage the cardiac tissue, and the folded configuration that is adapted to be administered to the patient's heart； a self-expanding ear skirt (616； 716； 816； 916) arranged in the ear region (606； 706； 806； 906)； a self-expanding ventricular skirt (628； 728； 828； 928) arranged in the ventricular region (610； 710； 810； 910)； a self-expanding annular region (608； 708； 808； 908) disposed between the atrial region (606； 706； 806； 906) and the ventricular region (610； 710； 810； 910)； a first self-expanding anterior flange (624； 724； 824； 924) disposed in an anterior part of the self-expanding framework in the ventricular region (610； 710； 810； 910)； and a self-expanding rear flange (630； 730； 830； 930) on a rear part of the self-expanding framework in the ventricular region, in which the length of the strut or the axial position of the anterior or posterior flanges along the framework is such that, after removal of the restriction provided by the outer sheath, a portion of the first self-expanding front flange and a portion of the self-expanding rear flange is partially self-expanding radially outwardly, the first anterior flange is radially self-expanding outwardly Before the ventricular skirt is radially self-expanding outwards, the ventricular skirt is radially self-expanding outwards before the posterior flange ends self-expanding, and the posterior flange ends self-expanding after the ventricular skirt self-expands
