## Abstract

Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together include a first member, a second member, and a connecting member extending between the first and second members. One of the first and second members has a configuration alterable by a deployment wire to permit release of the fastener from the deployment wire after deployment and without causing excessive tissue trauma.

## Claims

### Claim 1

A method for mounting a fastener onto a deployment wire, comprising:
providing a fastener and a deployment wire, the fastener including a first member and a second member, connecting the first member to the second member by a connecting member that is not the deployment wire, only the first member having a through channel dimensioned to be slidingly received on the deployment wire and a slit configured to be made larger so that the deployment wire can be snapped onto and released from the through channel;
the slit having a first elongated edge and a second elongated edge, the first and second elongated edges being spaced apart; and
snapping the deployment wire through the slit and into the through channel by moving the first and second elongated edges farther apart to accommodate the deployment wire.

### Claim 2 (depends on 1)

The method for mounting a fastener onto a deployment wire of claim 1, wherein the first member includes a distal end and a proximal end, the slit extending between the distal and proximal ends and communicating with the through channel, further comprising expanding the slit to accommodate a diameter of the deployment wire.

### Claim 3 (depends on 2)

The method for mounting a fastener onto a deployment wire of claim 2, wherein the slit has a width dimension that is smaller than a diameter of the through channel.

### Claim 4 (depends on 3)

The method for mounting a fastener onto a deployment wire of claim 3, wherein the deployment wire has a diameter and as the deployment wire is snapped through the slit, the first and second edges move apart a distance equal to the diameter of the deployment wire.

### Claim 5 (depends on 4)

The method for mounting a fastener onto a deployment wire of claim 4, wherein the distal end of the first member has a pointed distal tip thereby providing less resistance when the deployment wire is snapped through the slit.

### Claim 6 (depends on 5)

The method for mounting a fastener onto a deployment wire of claim 5, wherein the first member is formed from a flexible polymer material taken from the group consisting of polypropylene, polyethylene, polyglycolic acid, polyurethane, and thermoplastic elastomer.
