Abstract

A method and device are provided for closing a port site incision after a minimally invasive surgical procedure is performed. The closure device includes an access device and a suture needle. A body of the access device has a proximal portion and a distal portion and defines a channel that extends between the proximal and distal portions. A head of the access device is supported on the proximal portion of the body. The suture needle includes a shaft having a proximal portion and a distal portion, and a curved portion that extends from the distal portion of the shaft and includes a tip configured to penetrate tissue. The shaft extends through and is movable within a slot in the head to move the curved portion of the suture needle from an inactive position located within the channel to an active position positioned located externally of the channel.

First claim

What is claimed is:

1. A closure device for closing a port site incision, the closure device comprising:
an access device defining a longitudinal axis and including a body defining a cutout and a head defining a slot, the body having a proximal portion and a distal portion and defining a channel that extends between the proximal and distal portions, the head being supported on the proximal portion of the body; and
a suture needle including a shaft and a curved portion, the shaft having a proximal portion and a distal portion, the curved portion extending from the distal portion of the shaft and having a tip configured to penetrate tissue, the tip extending in a direction towards the head of the access device, wherein the proximal portion of the shaft extends through and is movable laterally within the slot in the head to move the curved portion of the suture needle from an inactive position located within the channel through the cutout to an active position positioned located externally of the channel.

2. The closure device of claim 1 , wherein the head of the access device has a first diameter and the body of the access device has a second diameter, the first diameter being greater than the second diameter.

3. The closure device of claim 1 , wherein the cutout in the body of the access device defines a vertical slot that is dimensioned to facilitate passage of the curved portion of the suture needle from within the channel into a body cavity.

4. The closure device of claim 1 , wherein the distal portion of the body of the access device includes a tapered end, the tapered end facilitating passage of the body of the access device through the port site incision.

5. The closure device of claim 1 , further including an actuator knob secured to the shaft of the suture needle.

6. The closure device of claim 5 , wherein the actuator knob is slidably supported on the head of the access device and is movable laterally along the slot to move the suture needle between the inactive position and the active position.

7. The closure device of claim 1 , wherein the suture needle has a J-shaped configuration.

8. The closure device of claim 7 , wherein the tip of the suture needle extends towards the head of the access device.

9. The closure device of claim 8 , further including a suture secured to the suture needle.

10. The closure device of claim 9 , wherein the suture needle includes an eye, the suture extending through the eye to couple the suture to the suture needle.

11. The closure device of claim 10 , wherein the head of the access device defines a suture hole, the suture extending from the eye of the suture needle through the suture hole.

12. A closure device for closing a port site incision, the closure device comprising:
an access device defining a longitudinal axis and including a body defining a vertical cutout and a head defining a horizontal slot, the body having a proximal portion and a distal portion and defining a channel that extends between the proximal and distal portions, the head being supported on the proximal portion of the body; and
a suture needle including a shaft and a curved portion, the shaft having a proximal portion and a distal portion, the curved portion extending from the distal portion of the shaft and having a tip configured to penetrate tissue, the tip extending in a direction towards the head of the access device, wherein the proximal portion of the shaft extends through and is movable laterally within the horizontal slot in the head to move the curved portion of the suture needle through the vertical cutout from an inactive position located within the channel to an active position positioned located externally of the channel.

13. The closure device of claim 12 , wherein the head of the access device has a first diameter, and the body of the access device has a second diameter, the first diameter being greater than the second diameter.

14. The closure device of claim 12 , wherein the distal portion of the body of the access device includes a tapered end, the tapered end facilitating passage of the body of the access device through the port site incision.

15. The closure device of claim 12 , further including an actuator knob secured to the shaft of the suture needle.

16. The closure device of claim 15 , wherein the actuator knob is slidably supported on the head of the access device and is movable laterally along the slot to move the suture needle through the vertical cutout between the inactive position and the active position.

17. The closure device of claim 12 , wherein the suture needle has a J-shaped configuration.

18. The closure device of claim 17 , wherein the tip of the suture needle extends towards the head of the access device.

19. The closure device of claim 18 , further including a suture, the suture needle having an eye and the suture extending through the eye to couple the suture to the suture needle.

20. The closure device of claim 19 , wherein the head of the access device defines a suture hole, the suture extending from the eye of the suture needle through the suture hole.
