## Abstract

Methods and devices are provided to allow the same component used to access a surgical site to assist in closing the surgical opening in which it was disposed. In one exemplary embodiment a flexible retractor is provided that includes proximal and distal ends and a lumen extending therethrough. A wound closure component is associated with the flexible retractor and is configured to engage tissue adjacent to a surgical incision in which the retractor is disposed and move tissue from one side of the surgical incision toward a second side of the surgical incision to assist in closing the surgical incision. In one embodiment the wound closure component includes strands of suture having hooks disposed on a distal end. In another embodiment the wound closure component includes a ring having hooks disposed around a circumference of the ring. Exemplary methods for closing a surgical opening are also provided.

## Claims

### Claim 1

A surgical access device, comprising:
a housing having an opening extending therethrough and configured to be positioned adjacent to a surgical incision;
a flexible retractor removably and replaceably coupled to the housing and configured to be positioned within the surgical incision to provide access to a body cavity, the retractor having a proximal end and a distal end; and
a wound closure component associated with the distal end of the retractor, the wound closure component having a plurality of hooks and a plurality of strands of suture extending through the retractor from the proximal end to the distal end, each hook of the plurality of hooks being coupled to one strand of suture of the plurality of strands of suture, the wound closure component being configured to engage tissue adjacent to the surgical incision with the plurality of hooks and selectively move tissue from one side of the surgical incision toward a second side of the surgical incision to assist in closing the surgical incision, and the plurality of strands of suture including an actuating suture configured to collapse a distal end of the wound closure component.

### Claim 2 (depends on 1)

The surgical access device of claim 1, wherein the distal end of the wound closure component further comprises a distal ring through which the actuating suture is disposed, the actuating suture being configured to collapse the distal ring to close the surgical incision.

### Claim 3 (depends on 1)

The surgical access device of claim 1, wherein proximal ends of strands of suture of the plurality of strands of suture are configured to be approximated and pulled together in a direction away from the surgical incision, thereby pulling closer together the tissue with which the plurality of hooks is engaged.

### Claim 4 (depends on 3)

The surgical access device of claim 3, further comprising an actuation mechanism coupled to the proximal ends of the strands of suture and configured to approximate the strands of suture toward each other and in a direction away from the surgical incision.

### Claim 5

A flexible retractor for use in a surgical procedure, comprising:
a body having a proximal end and a distal end with a lumen extending therethrough and defining a working channel; and
a wound closure component associated with the distal end, the wound closure component having a plurality of hooks and a plurality of strands of suture extending through the body from the proximal end to the distal end, each hook of the plurality of hooks being coupled to one strand of suture of the plurality of strands of suture, the wound closure component being configured to engage tissue adjacent to a surgical incision with the plurality of hooks and approximate tissue adjacent to the surgical incision to assist in closing the surgical incision, and the plurality of strands of suture including an actuating suture configured to collapse a distal end of the wound closure component.

### Claim 6 (depends on 5)

The flexible retractor of claim 5, wherein the distal end of the wound closure component further comprises a distal ring through which the actuating suture is disposed, the actuating suture being configured to collapse the distal ring to close the surgical incision.

### Claim 7 (depends on 5)

The flexible retractor of claim 5, wherein the plurality of strands of suture are configured to be manipulated to approximate the tissue with which the plurality of hooks is are engaged.

### Claim 8

A method for repairing a surgical wound, comprising:
positioning a surgical access retractor through an opening in tissue, the retractor including a wound closure component having a distal ring, a plurality of hooks, and a plurality of strands of suture disposed through and around the distal ring, wherein each hook of the plurality of hooks is coupled to one strand of suture of the plurality of strands of suture and the plurality of strands of suture including an actuating suture;
engaging the plurality of hooks with tissue adjacent to a distal end of the retractor;
manipulating the actuating suture to collapse the distal ring to approximate tissue adjacent to the opening in tissue, thereby closing the surgical wound; and
suturing the approximated tissue.

### Claim 9 (depends on 8)

The method for repairing a surgical wound of claim 8, further comprising moving the wound closure component toward an outside environment.

### Claim 10 (depends on 8)

The method for repairing a surgical wound of claim 8, further comprising cinching the plurality of strands of suture coupled to the tissue adjacent to the distal end of the retractor toward each other.

### Claim 11 (depends on 8)

The method for repairing a surgical wound of claim 8, wherein the step of manipulating the actuating suture to collapse the distal ring further comprises applying tension to the actuating suture.
