Patent ID: 8500760

Claim:
A tacking device for engaging tissue, the tacking device comprising: a main body having proximal and distal ends; a plurality of proximal deployable members having contracted states during delivery and expanded states, wherein the proximal deployable members extend proximally from the proximal end of the main body; a plurality of distal deployable members having contracted states during delivery and expanded states, wherein the distal deployable members extend distally from the distal end of the main body and are configured to engage tissue in the expanded states; and a hook member extending from at least one of the proximal deployable members, wherein the hook member comprises a substantially identical configuration when the proximal and distal deployable members are in the expanded and contracted states, wherein the proximal deployable members and the distal deployable members each comprise hook-shaped configurations in the expanded states that are substantially concave relative to the main body, wherein a radius of curvature of the hook member is less than a radius of curvature of each of the proximal deployable members when the proximal and distal deployable members are in the expanded states, and wherein the hook member comprises a convex curvature relative to the main body when the proximal deployable members are in the expanded states.
