The present embodiments provide a tacking device for engaging tissue, which may be useful for facilitating closure of a bodily opening. The tacking device comprises a main body having proximal and distal ends, and at least one distal deployable member having contracted and expanded states that extends distally from the distal end of the main body. In use, after the distal deployable members have been at least partially expanded at a preliminary location, the distal deployable members may be contracted to permit repositioning at a different, final location. In one exemplary method, at least two tacking devices may be deployed to at least partially surround an opening in tissue, and a suture coupled to the first and second tacking devices may be actuated to facilitate closure of the opening.

Les présents modes de réalisation portent sur un dispositif d'agrafage destiné à engager un tissu, pouvant être utile pour faciliter la fermeture d'une ouverture corporelle. Le dispositif d'agrafage comprend un corps principal comportant un corps principal ayant des extrémités proximale et distale, et au moins un élément déployable distal ayant des états contractés et étendus et s'étendant de manière distale à partir de l'extrémité distale du corps principal. En cours d'utilisation, après que les éléments déployables distaux aient été au moins partiellement étendus dans un emplacement préliminaire, on peut contracter les éléments déployables distaux afin de permettre le repositionnement dans un emplacement final différent. Dans un exemple de mode de réalisation, on peut déployer au moins deux dispositifs d'agrafage afin d'entourer au moins partiellement une ouverture dans un tissu, et on peut actionner une suture couplée au premier et au second dispositif d'agrafage afin de faciliter la fermeture de l'ouverture.
