Abstract

A vascular closure system includes a body portion, an anchor, at least one suture member, and a plurality of needles. The anchor assembly includes a hub and a wire assembly. The hub has at least one aperture defined in a sidewall thereof. The wire assembly includes an actuator member extending proximally through the body portion and hub, and at least one pre-formed wire having a free proximal end and a distal end that is connected to the actuator member. Withdrawing the actuator member extends the proximal end of the at least one pre-formed wire out of the at least one aperture to capture a portion of the vessel wall between the pre-formed wire and the body portion. The plurality of needles extend through the vessel wall adjacent to the vessel puncture and are configured to connect to the at least one suture member.

Claims

1. A vascular closure system, comprising:

a body portion;

an anchor assembly positionable through a vessel puncture in a vessel wall of a vessel, the anchor assembly including a hub and a wire assembly, the hub having at least one aperture defined in a sidewall thereof, and the wire assembly including an actuator member extending proximally through the body portion and hub, and at least one pre-formed wire having a proximal end and a distal end connected to the actuator member, wherein withdrawing the actuator member extends the proximal end of the at least one pre-formed wire out of the at least one aperture to capture a portion of the vessel wall between the at least one pre-formed wire and the body portion;

at least one suture member positioned distal of the body portion;

a plurality of needles extendable through the portion of the vessel wall adjacent to the vessel puncture, the plurality of needles being configured to connect to the at least one suture member;

wherein withdrawal of the plurality of needles through the portion of the vessel wall positions the at least one suture member through the portion of the vessel wall.

2. A vascular closure system according to claim 1 wherein the at least one pre-formed wire comprises a J-shape.

3. A vascular closure system according to claim 1, wherein the wire assembly includes first and second pre-formed wires arranged on opposite sides of the actuator member.

4. A vascular closure system according to claim 1, wherein the proximal end of the at least one pre-formed wire is pre-positioned in the at least one aperture.

5. A vascular closure system according to claim 1, wherein the at least one pre-formed wire includes a contact tip at the proximal end, the contact tip having a bulbous shape.

6. A vascular closure system according to claim 1, wherein the proximal end of the at least one pre-formed wire extends radially outward upon withdrawal of the actuator member.

7. A vascular closure system according to claim 3, wherein the proximal end of the first pre-formed wire extends further proximally than the proximal end of the second pre-formed wire.

8. A vascular closure system according to claim 1, wherein the at least one pre-formed wire is welded to the actuator member.

9. A vascular closure system according to claim 1, wherein the body portion includes a handle assembly at a proximal end thereof, and first and second actuators operable to actuate the actuator member and the plurality of needles, respectively.

10. A vascular closure device, comprising:

a body portion;

a hub positionable through a puncture in a vessel and having at least one aperture defined in a sidewall thereof;

a wire assembly including an actuator wire extending through the body portion and hub, and at least one anchor wire having a distal end connected to the actuator wire and a proximal end that extends out of the at least one aperture to capture a portion of a wall of the vessel between the anchor wire and the body portion upon withdrawal of the actuator wire;

first and second suture members positioned within the vessel;

first and second pairs of needles operable to advance through the portion of the vessel adjacent to the puncture, connect to the first and second suture members, and be withdrawn through the portion of the vessel to position the first and second suture members through the portion of the vessel.

11. A vascular closure device according to claim 10, wherein the at least one anchor wire includes first and second anchor wires configured to extend through first and second apertures defined in the sidewall of the hub.

12. A vascular closure device according to claim 10, further comprising a blood location port positioned proximal of the at least one aperture.

13. A vascular closure device according to claim 10, wherein the at least one anchor wire has a J-shape when in a rest position.

14. A vascular closure device according to claim 10, wherein the actuator wire has at least one groove sized to receive the distal end of the at least one anchor wire.

15. A vascular closure device according to claim 14, wherein the distal end of the at least one anchor wire is welded within the at least one groove.

16. A method of positioning sutures across a vascular opening in a vessel wall, comprising:

providing a vascular closure device having a body portion, an anchor assembly, at least one length of suture, and a plurality of needles, the anchor assembly including a hub, an actuator wire, and a pre-formed wire having a distal end connected to the actuator wire;

inserting the anchor assembly and at least one length of suture through the vascular opening;

withdrawing the actuator wire to advance a proximal end of the pre-formed wire through a sidewall of the hub;

capturing a portion of the vessel wall between the pre-formed wire and a distal end of the body portion;

advancing the plurality of needles through the portion of the vessel wall adjacent to the vascular opening;

connecting the plurality of needles to the at least one length of suture;

withdrawing the plurality of needles to position the at least one length of suture through the vessel wall adjacent to the vascular opening;

advancing the actuator wire to move the pre-formed wire into the hub;

removing the anchor assembly through the vascular opening.

17. The method of claim 16, further comprising providing a plurality of pre-formed wires that each extend through a separate wire aperture in the sidewall of the hub.

18. The method of claim 16, wherein advancing a proximal end of the pre-formed wire positions a bend portion of the pre-formed wire in contact with the vessel wall.

19. The method of claim 16, wherein advancing the actuator wire to move the pre-formed wire into the hub includes retracting all but a proximal tip of the pre-formed wire into the hub.

20. The method of claim 16, further comprising maintaining a generally linear shape in the pre-formed wire prior to advancing the proximal end of the pre-formed wire through the sidewall of the hub, and providing a contoured shape in the pre-formed wire after advancing the proximal end through the sidewall of the hub.
