Abstract

Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot of the device can be inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot can carry suturing attachment cuffs with one end of the cuff adapted to receive a needle, while the other end receives suture. A portion of the foot and/or lumen of the shaft can receive a portion of the suture and can include friction reducing structure that aid with movement of the sutured during removal of the cuffs from within the penetration.

Claims

1. A device for suturing an opening in a tissue, the device comprising:

a shaft suitable for insertion into a vessel through a puncture;

an elongate foot movably mounted to the shaft, the elongate foot having a slot formed therein, the slot comprising at least one friction reducing structure comprising a plurality of recessed portions and a plurality of raised portions;

an actuator extending distally to the foot, movement of the actuator moving the foot from a low profile configuration to a deployed configuration extending laterally from the shaft;

a suture supported by the foot; and

a needle advanceable from the shaft through the tissue and to the deployed foot.

2. The device of claim 1, wherein the suture passes through at least a portion of the friction reducing structure in the slot.

3. The device of claim 1, wherein the elongate foot comprises a penetrator receptacle.

4. The device of claim 3, wherein the penetrator receptacle communicates with the slot, a link extending from a fitting disposed in the penetrator receptacle into the slot.

5. The device of claim 1, wherein movement of the actuator slides the foot axially and pivots the foot relative to the shaft.

6. A device for suturing an opening in a tissue, the device comprising:

a shaft;

an articulatable member movably mounted to the shaft and including a first needle receptacle, a second needle receptacle, and a slot associated with the first needle receptacle, the slot comprising a friction reducing structure comprising a plurality of recessed portions and a plurality of raised portions;

an actuator extending to the articulatable member, movement of the actuator sliding the articulatable member from a low profile configuration to a transverse deployed configuration;

a suture extending between the first needle receptacle and the second needle receptacle through the slot and cooperating with the friction reducing structure; and

a plurality of needles advanceable from the shaft through the tissue and to the deployed articulatable member.

7. The device of claim 6, wherein the slot extends across the articulatable member from the first needle receptacle to the second needle receptacle.

8. The device of claim 6, wherein the slot includes a first diameter that is smaller than a second diameter.

9. The device of claim 8 wherein the slot includes an first inside diameter of about 0.030 inches and a second inside diameter of about 0.040 inches.

10. The device of claim 6, wherein the movement of the actuator slides and pivots the articulatable member from the low profile configuration to the transverse deployed configuration.

11. The device of claim 10, wherein the suture-bearing surface comprises another friction reducing structure.

12. The device of claim 10, further comprising a moveable flap extending over a portion of the slot.

13. The device of claim 6, further comprising a tangential slot extending from the first needle receptacle.

14. The device of claim 6, wherein the plurality of needles comprises a two-part needle having an outer sheath and an inner core.

15. The device of claim 6, further comprising a suture-bearing surface disposed distally of the elongate foot and configured to receive the suture.

16. A device for suturing an opening in a tissue, the device comprising:

a shaft suitable for insertion along a tissue tract and into a vessel through a puncture;

an elongate foot movably mounted to the shaft, the elongate foot comprises a plurality of first needle receptacles at a first end of the elongate foot and a plurality of second needle receptacles at a second end of the elongate foot, the elongate foot having a slot formed therein, the slot comprising at least one recessed portion and at least one raised portion disposed on an interior surface of the slot;

an actuator extending along the shaft distally to the foot, movement of the actuator sliding the foot axially and pivoting the foot from a low profile configuration aligned along the shaft to a deployed configuration extending laterally from the shaft;

a suture supported by the foot, the suture passing through at least a portion of the slot that includes the at least one recessed portion and the at least one raised portion; and

a needle advanceable from the shaft through the tissue and to the deployed foot.

17. The device of claim 16, further comprising a suture-bearing surface disposed distally of the elongate foot and configured to receive the suture.

18. The device of claim 17, further comprising another slot extending from the suture-bearing surface, the another slot including a friction reducing structure.
