A suture anchoring device includes a fastener body composed of a tube and a spool is mounted within the tube for rotation relative to the tube. Suture material is wrapped about the spool such that pulling of the suture material causes rotation of the spool within the tube. A one-way locking mechanism allows the spool to rotate freely in a first direction and prevents rotation in an opposite direction. A method for creating a tissue fold includes deploying a first suture anchoring device within the tissue with suture material extending proximally from the first suture anchoring device, deploying a second suture anchoring device within the tissue with a distal portion of the suture material extending between the first suture anchoring device and a proximal portion of the suture material extending proximally from the second suture anchoring device, and applying tension to the suture material to draw portions of the tissue together to form a tissue fold.

L'invention concerne un dispositif d'ancrage de suture comprenant un corps de dispositif de fixation composé d'un tube et d'une bobine montée dans le tube pour tourner par rapport au tube. Du matériau de suture est enroulé autour de la bobine de telle sorte qu'en tirant le matériau de suture on provoque une rotation de la bobine dans le tube. Un mécanisme de blocage unidirectionnel permet à la bobine de tourner librement dans une première direction et empêche une rotation dans la direction opposée. Un procédé pour créer un pli de tissu comprend le déploiement d'un premier dispositif d'ancrage de suture dans le tissu, le matériau de suture s'étendant de manière proximale à partir du premier dispositif d'ancrage de suture, le déploiement d'un second dispositif d'ancrage de suture dans le tissu, une partie distale du matériau de suture s'étendant entre le premier dispositif d'ancrage de suture et une partie proximale du matériau de suture s'étendant de manière proximale à partir du second dispositif d'ancrage de suture, et l'application d'une traction sur le matériau de suture pour tirer des parties du tissu ensemble pour former un pli de tissu.
