Heart chamber prosthetic valve implantation with raised valve portion and single lumen fixation for preservation, replacement, and / or replacement of native valve function

摘要

Various embodiments of the present invention comprise a raised valve portion and (1) preservation of native valve function; (2) initial preservation of native valve function with complete replacement of subsequent native valve function. (3) a complete replacement of the native valve function; and / or (4) a valve leaflet that deviates into the left atrial cavity above the upper annular surface to preserve as much as possible the native valve leaflet functionality. A single-lumen retractable and expandable prosthetic valve implantation device that includes the ability to alleviate dysfunctional leaflet deviation distances by preventing forward deflection of the device. The expanded and implanted device does not extend beyond the boundary of the subject's heart chamber, e.g., the left atrium, thereby providing complete replacement of subsequent native valve function, if necessary. Allows preservation of the remaining native valve function involved. [Selection] Figure 1
