## Abstract

Methods for deploying a fastener to close an incision or wound involve exposing the inner surface of each opposing side of the incision and inserting down into the exposed inner surfaces from above the fastener.

## Claims

### Claim 1

A method for closing a surgical incision or wound in skin tissue using a fastener having a pair of legs and a bridge section between the two legs, each leg section including at least one barb, comprising:
raising two sides of the incision or wound above a plane of an external surface of the skin tissue;
pulling skin tissue from each side of the incision or wound in a direction generally up and away from the incision or wound at an acute angle relative to the external surface of the skin tissue to expose a portion of an underside of a dermal layer of each side of the incision or wound; and
deploying the fastener such that each of the two legs simultaneously penetrate the exposed portion of the underside of the dermal layer of each side of the incision or wound from above and generally perpendicular to the plane of the external surface of the skin tissue.

### Claim 2 (depends on 1)

The method of claim 1 wherein the fastener is bioabsorbable.

### Claim 3 (depends on 1)

The method of claim 1 wherein the pulling and deploying steps include use of an insertion mechanism having a first foot and a second foot spaced apart by a gap, each foot including a lower surface adapted to contact the external surface of the skin tissue on one side of the incision or wound such that the skin tissue from each side of the incision or wound is pulled over an upper surface of the respective foot to expose the portion of the underside of the dermal layer of each of the sides of the incision or wound in the gap.

### Claim 4

A method for closing two sides of an incision in skin tissue, comprising:
engaging one of the sides of the incision to expose a first portion of an underside of a dermal layer of that side of the incision;
engaging the other side of the incision to expose a second portion of the underside of the dermal layer of the other side of the incision;
simultaneously penetrating each of the exposed first and second portions of the undersides of the dermal layer with a fastener such that the fastener penetrates in a substantially vertical direction relative to a horizontal plane of an external surface of the skin tissue; and
releasing the sides of the incision to allow the skin tissue to relax with the fastener deployed completely below the external surface of the skin tissue thereby holding the two sides of the incision in close contact.

### Claim 5 (depends on 4)

The method of claim 4 wherein the fastener comprises a bioabsorbable fastener that includes two leg sections and a bridge section between the two leg sections, each leg section including at least one barb that is oriented to resist dislodgement from the skin tissue after the fastener is deployed into the skin tissue.

### Claim 6 (depends on 5)

The method of claim 5 where the bridge section and the two leg sections comprise a single piece of material.

### Claim 7 (depends on 5)

The method of claim 5 wherein the releasing step results in the barb of each leg section resisting dislodgement from one side of the incision, and wherein the bridge section holds the two sides of the incision together.
