Described here are devices, methods, and kits for deployment of tissue anchors. In some variations, the devices described here comprise a shaft defining a lumen for housing at least one anchor therein (the anchor having an eyelet) and a mechanism for deploying the anchor distally from the lumen, wherein the inner diameter of the lumen is the same size or smaller than the diameter of the eyelet of the anchor to be disposed therein when the anchor is in an expanded configuration. In some variations, the methods comprise loading an anchor within a lumen of a shaft (where the anchor comprises an eyelet and the shaft has a slot therethrough), passing a linking member through the slot and through the eyelet of the anchor, and deploying the anchor. Other methods comprise loading an anchor within a lumen of a shaft, and deploying the anchor distally from the lumen.

La présente invention décrit des dispositifs, des procédés et des trousses de déploiement d~ancrages tissulaires. Dans certaines variantes, les dispositifs décrits ici comprennent un arbre définissant une lumière destinée à recevoir au moins un ancrage (l~ancrage comportant un AEillet) et un mécanisme pour déployer l~ancrage de manière distale à partir de la lumière. Le diamètre intérieur de la lumière est de la même taille ou inférieur au diamètre de l~AEillet de l'ancrage qui doit être placé à l'intérieur de celle-ci lorsque l'ancrage est dans une configuration expansée. Dans certaines variantes, les procédés comprennent les étapes consistant à charger un ancrage dans la lumière d~un arbre (l~ancrage comportant un AEillet et l~arbre une fente à travers celui-ci), à faire passer un élément de liaison à travers la fente et à travers l~AEillet de l~ancrage et à déployer l~ancrage. D~autres procédés comprennent les étapes consistant à charger un ancrage dans la lumière d~un arbre et à déployer l~ancrage de manière distale à partir de la lumière.
