An elongate body (10) including a proximal and distal anchor, and a bridge (16) between the proximal (12) and distal (14) anchors. The bridge has an elongated state, having first axial length, and a shortened state, having a second axial length, wherein the second axial length is shorter than the first axial length. A resorbable thread (420) may be woven into the bridge to hold the bridge in the elongated state and to delay the transfer of the bridge to the shortened state. In an additional embodiment, there may be one or more central anchors between the proximal and distal anchors with a bridge connecting adjacent anchors.

La présente invention a trait à un corps de forme allongée (10) comportant des éléments d'ancrage proximal et distal, et un pont (16) entre les éléments d'ancrage proximal (12) et distal (14). Le pont présente un état allongé, ayant une première longueur axiale, et un état raccourci, ayant une deuxième longueur axiale, la deuxième longueur axiale étant inférieure à la première longueur axiale. Un fil résorbable (420) peut être tissé dans le pont pour le maintien du pont dans l'état allongé et pour retarder le transfert du pont dans l'état raccourci. Dans un mode de réalisation supplémentaire, un ou plusieurs élément(s) d'ancrage central/centraux peut/peuvent être prévu(s) entre les éléments d'ancrage proximal et distal avec un pont reliant des élément d'ancrage adjacents.
