IMPLANT DE VALVULE PROTHETIQUE DE CHAMBRE CARDIAQUE PRESENTANT DES SECTIONS DE BASE, DE RESSORT ET DE DOME PRESENTANT UN ANCRAGE DE CHAMBRE UNIQUE POUR LA CONSERVATION, LA SUPPLEMENTATION ET/OU LE REMPLACEMENT DE LA FONCTION DE LA VALVULE NATIVE
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.
