本发明的各个实施例包括单室可瘪缩和可扩张的假体瓣膜植入装置，其包括以下能力：(1)保持原生瓣膜功能；(2)初始保持原生瓣膜功能，随后完全置换原生瓣膜功能；(3)完全置换原生瓣膜门功能；和/或(4)通过防止脱垂小叶前偏移到上环形表面上方并进入左心房腔室来减轻功能障碍小叶的脱垂距离，以便尽可能长时间地保留原生小叶功能。扩张和植入装置不延伸超出受试者心脏腔室(例如左心房)的边界，从而能够保持任何剩余的原生瓣膜功能，并且随后在需要时完全置换原生瓣膜功能。 Various embodiments of the present invention comprise a single-chamber collapsible and expandable prosthetic valve implant device with an elevated valve section and comprising the following capabilities: (1) preservation of native valve functionality; (2) initial preservation of native valve functionality with subsequent full replacement of native valve functionality; (3) full replacement of native valve functionality; and/or (4) mitigation of the prolapsing distance of the dysfunctional leaflets by preventing the anterior excursion of the prolapsing leaflets above the upper annular surface and into the left atrial chamber in order to preserve native leaflet functionality for as long as possible. The expanded and implanted device does not extend beyond the boundaries of the subject heart
