Heart chamber prosthetic valve implant with base, mesh and dome sections with single chamber anchoring for preservation, supplementation and/or replacement of native valve function
Various embodiments of the present invention comprise a single-chamber collapsible and expandable prosthetic valve implant device 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 chamber, e.g., the left atrium, thereby enabling the preservation of any remaining native valve functionality with subsequent full replacement of native valve functionality if and when needed.
