1. An implantable fastener for fastening layers of tissue together, comprising:

  • an elongated support;

    a distal anchor member having a first end portion connected to the support and a second end portion movable on the support, the distal anchor member being configured to be movable from a reduced profile position to a deployed position when a spacing between the first and second end portions is reduced;

    a proximal anchor member having first and second end portions movable on the support, the proximal anchor member being configured to be movable from a reduced profile position to a deployed position when a spacing between the first and second end portions of the proximal anchor member is reduced, the proximal anchor member being spaced from the distal anchor member a distance sufficient to position the layers of tissue together between the proximal and distal anchor members; and

    at least one retainer on a proximal end portion of the support, the retainer engaging one of the end portions of the proximal anchor member when at least the proximal anchor member is in the deployed position so that at least the proximal anchor member is retained in the deployed position.
