The present embodiments provide a tacking device for engaging tissue, which may be useful for coupling a graft to tissue or facilitating closure of a bodily opening. In one embodiment, the tacking device comprises a main body having proximal and distal ends, and further comprises at least one proximal deployable member and at least one distal deployable member, each having contracted and expanded states. The proximal deployable members extend proximally from the proximal end of the main body, while the distal deployable members extend distally from the distal end of the main body. In one embodiment, a hook member extends from at least one of the proximal deployable members. In use, the hook member may be engaged, for example, using a loop member coupled to a stylet, thereby facilitating controlled release of the tacking device and allowing repositioning of the tacking device after at least partial deployment of the distal deployable members. |
