Patent ID: 8337514

Claim:
A fastener assembly for use in a mammalian body, comprising: a fastener including a first member, a second member, wherein the first and second members have first and second ends; a connecting member fixed to each of the first and second members intermediate the first and second ends and extending between the first and second members, and one of the first and second members has a longitudinal axis and a through channel along the axis; a deployment wire arranged to be slidingly received by the through channel of the one of the first and second members and to pierce into the tissue; and a pusher that pushes the one of first and second members into the tissue while on the deployment wire; wherein the pusher is tubular and includes a distal end, a tubular sidewall, a lumen, and an opening in the sidewall communicating with the lumen; wherein the pusher is carried on the tissue piercing deployment wire, the tissue piercing deployment wire extending through the sidewall opening, into the lumen and beyond the distal end of the pusher; wherein the one of the first and second members is carried on the deployment wire between a tip end of the deployment wire and the distal end of the pusher arranged to pierce into the tissue upon being pushed by the pusher; wherein the one of the first and second members has a cross-sectional dimension and the tip end has a cross-sectional dimension that is greater than or equal to the cross-sectional dimension of the through channel such that the one of the first and second members has a configuration that is alterable by the tissue piercing deployment wire that permits release of the fastener from the tissue piercing deployment wire upon relative movement of the one of the first and second members and the tissue piercing deployment wire.
