A holder (24) for an annulopiasty ring (22) having a template (26) defining a proximal face opposite the distal face (50), and a peripheral edge (28) about which the annulopiasty ring conforms. The annulopiasty ring anchors to the template using one or more flexible filaments (110). The template includes a single cutting well (48) on its proximal face over which the flexible filament is suspended. Desirably, the single cutting well is located adjacent the peripheral edge so as to be away from any handle connections for ease of access. The flexible filament emerges above the proximal face of the template at only one location at the cutting well, thus presenting a one cut quick- release structure that is highly visible to the surgeon.

La présente invention concerne un dispositif de maintien (24) pour anneau d'annuloplastie (22) dont le gabarit (26) définit une face proximale en opposition à la face distale (50), et un rebord périphérique (28) dont l'anneau d'annuloplastie épouse extérieurement la forme. L'anneau d'annuloplastie s'ancre au gabarit au moyen d'un ou de plusieurs filaments souples (110). La face proximale du gabarit comporte un unique puits de découpe (48) au-dessus duquel est suspendu le filament souple. De préférence, pour une meilleure accessibilité, l'unique puits de découpe est situé contre le bord périphérique de façon à être éloigné de toutes les liaisons de manipulation. Le filament souple dépasse au-dessus de la face proximale du gabarit en un seul endroit au niveau du puits de découpe, ce qui fait qu'il présente une structure de dégagement rapide à un seul trait de coupe, parfaitement visible pour le chirurgien.
