A member of a rigid flexible elastic material, the member including a body portion and an aperture portion with the member adapted for delivery through an axial longitudinal channel of a percutaneous delivery subsystem, the aperture portion including an expanded mode having a lateral dimension greater than an inner diameter of the channel when the aperture portion extends outside the channel and a collapsed mode wherein the lateral dimension is not greater than the inner diameter of the channel when the aperture portion is within the channel, the channel including a first axial opening and a second axial opening with the aperture portion transitioning from the expanded mode to the collapsed mode when inserted into the openings and the aperture transitioning from the collapsed mode to the expanded mode when exiting from the openings.

La présente invention concerne un élément fait en un matériau élastique rigide souple. Cet élément comporte une partie corps et une partie ouverture, l'élément étant conçu pour se mettre en place en passant par le canal longitudinal axial d'un système de mise en place percutanée. La partie ouverture connaît un mode déployé présentant une dimension latérale supérieure au diamètre intérieur du canal lorsque la partie ouverture déborde extérieurement du canal, et un mode replié dans lequel la dimension latérale n'excède pas le diamètre intérieur du canal lorsque la partie ouverture se troue à l'intérieur du canal. Le canal comporte une première ouverture axiale et une deuxième ouverture axiale, la partie ouverture passant du mode déployé au mode replié lorsqu'elle est insérée dans les ouvertures, et passant du mode replié au mode déployé lors qu'elle ressort des ouvertures.
