A medical fastener having first undeployed shape for loading into an applier, and a second deployed shape for connecting tissue together. The fastener includes a crown having two ends and first and second legs one attached to each end of the crown. The legs are separated from one another when the fastener is in the first shape. The legs comprise first, second and third layers of material joined together. The first layer of material is a superelastic alloy having a relaxed configuration substantially in the second shape of the fastener. The second layer of material comprising a linear elastic material having a relaxed configuration substantially in the first shape of the fastener. The second layer of material has sufficient rigidity to keep the first layer in the first shape prior to the fastener being deployed. The third layer of material is disposed between the first and second layers and is a material which substantially prevents diffusion between the first and second layers of material.
