Abstract

A device is provided herein for deploying a suture in a puncture through a vessel wall of a blood vessel, the puncture disposed within a tissue tract of a patient body. The device includes a shaft suitable for insertion along the tissue tract and into the vessel through a puncture, a plurality of needles, each needle having a proximal end and a distal end suitable for forming a needle path through the vessel wall, wires associated with each needle, each wire having a distal end and a proximal end, and hooks coupled to each of the distal ends of each wire, each hook being configured to anchor the wire to an interior portion of the vessel wall.

Claims

1. A device for deploying a suture in a puncture through a vessel wall of a blood vessel, the puncture disposed within a tissue tract of a patient body, the device comprising:

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

a foot coupled to the shaft, the foot including a plurality of guide channels extending through the foot from a proximal side to a distal side of the foot;

a plurality of hollow needles, each needle having a proximal end, a distal end suitable for forming a needle path through the vessel wall, each needle configured to extend from the proximal side of the foot, through a respective guide channel of the plurality of guide channels, and distally beyond the distal side of the foot;

wires associated with each needle, each wire being slidably disposed within a hollow needle of the plurality of needles and having a distal end and a proximal end; and

hooks coupled to each of the distal ends of each wire, each hook being configured to anchor the wire to an interior portion of the vessel wall, the slidable movement of the wires and deployment of the hooks from within the plurality of hollow needles being independent from proximal movement of the needle.

2. The device of claim 1, wherein at least one hook is configured to be stored completely within one of the needles prior to deployment and to be extended beyond the distal end of the needle after deployment.

3. The device of claim 1, wherein the foot is configured to move from a low profile configuration aligned along the shaft to a deployed configuration extending laterally from the shaft and along the vessel and wherein the first and second needles are advanced from a stored positioned within the shaft through the vessel wall outside the puncture.

4. The device of claim 3, wherein the guide channels defined therein are configured for guiding the needles as the needles advance in cantilever and distally relative to the shaft.

5. The device of claim 1, further comprising a proximal body and a needle deployment handle coupled to the proximal end of the needles, wherein moving the needle deployment handle toward the proximal body deploys the needles.

6. The device of claim 5, further comprising a hook deployment handle, wherein moving the hook deployment handle distally relative to the needle deployment handle deploys the hooks.

7. The device of claim 6, further comprising a pull pin configured to retain the hook deployment handle in position relative to the needle deployment handle as the needle deployment handle is moved toward the proximal body to deploy the needles and is configured to be removed to allow the hook deployment handle to move distally relative to the needle deployment handle to deploy the hooks.

8. The device of claim 6, wherein the hook deployment handle has a push mandrel coupled thereto, the push mandrel being configured to deploy the hooks when the hook deployment handle is moved distally relative to the needle deployment handle.

9. The device of claim 1, wherein at least one of the hooks comprises a single tip configured to move away from at least one of the wires.

10. The device of claim 1, wherein at least one of the hooks comprises a plurality of tips configured to form a T-shape when deployed.

11. A device for deploying a suture in a puncture through a vessel wall of a blood vessel, the puncture disposed within a tissue tract of a patient body, the device comprising:

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

a foot coupled to the shaft, the foot including a plurality of guide channels extending through the foot from a proximal side to a distal side of the foot;

a plurality of hollow needles, each needle having a proximal end, a distal end suitable for forming a needle path through the vessel wall, and a needle deployment handle disposed at the proximal end of each needle, each needle configured to extend from the proximal side of the foot, through a respective guide channel of the plurality of guide channels, and distally beyond the distal side of the foot;

wires associated with each needle, each wire having a distal end and a proximal end and being disposed within a hollow needle of the plurality of hollow needles; and

hooks coupled to each of the distal ends of each wire, each hook being configured to anchor the wire to an interior portion of the vessel wall and having a proximally extending portion that initially extends towards the wire and subsequently extends outwardly away from the wire, each wire including a hook deployment handle disposed at the proximal end of the wire, the hook deployment handle slidably cooperating with a proximal end of the needle deplayment handle.

12. The device of claim 11, wherein at least one hook is configured to be stored completely within one of the needles prior to deployment and to be extended beyond the distal end of the needle after deployment.

13. The device of claim 11, wherein the hooks further comprise a sharpened tip.

14. The device of claim 11, wherein a portion of the hooks is flattened.

15. The device of claim 11, wherein the wire comprises a break-off location to separate the wire into two portions.

16. The device of claim 15, further comprising a hook deployment handle.

17. The device of claim 11, wherein the foot is configured to move from a low profile configuration aligned along the shaft to a deployed configuration extending laterally from the shaft and along the vessel.

18. The device of claim 11, further comprising a proximal body and a needle deployment handle coupled to the proximal end of the needles.
