Abstract

Methods and devices are provided for deploying and applying multiple suture anchors. In one embodiment, a surgical device is provided having a shaft configured to be introduced into a body, e.g., through a scoping device, and to deliver a plurality of suture anchors into tissue, preferably without the need to remove the shaft from the body. The shaft can have a plurality of channels, with each of the plurality of channels configured to seat at least one of a plurality of suture anchors. Each of the anchors can be removably seated in a channel such that the anchors can be removed from the device, such as by pulling on sutures attached to the respective anchors.

Claims

1. A surgical device, comprising:

a plurality of anchors;

a plurality of sutures, each of the plurality of anchors having one of the sutures coupled thereto; and

an elongate shaft having a tissue-penetrating tip at a distal end thereof, a plurality of channels formed in the elongate shaft each configured to seat one of the plurality of anchors, and an inner lumen isolated from the plurality of channels and extending through the elongate shaft, the sutures each at least partially extending through the inner lumen, and the plurality of channels being configured such that upon insertion of the shaft through tissue each of the anchors can be selectively retracted proximally relative to the shaft by pulling the suture coupled thereto to release the anchor from the channel in which the anchor is seated and engage tissue with the suture coupled thereto extending through the tissue.

2. The device of claim 1, wherein a distal portion of the shaft has a plurality of openings formed in an outer surface thereof and in communication with the plurality of channels, each of the plurality of openings being configured to allow one of the plurality of anchors to be retracted therethrough.

3. The device of claim 2, wherein each of the openings is configured to move from a substantially closed configuration when its associated anchor is seated in its associated channel to an open configuration when its associated anchor is retracted therethrough.

4. The device of claim 1, wherein the plurality of channels are arranged circumferentially around the inner lumen.

5. The device of claim 1, wherein the tissue-penetrating tip is formed on a penetrating element movably disposed in the inner lumen.

6. The device of claim 5, wherein a distal end of the tissue-penetrating tip is movable between a retracted configuration in which the distal end is contained within the inner lumen and a deployed position in which the distal end extends beyond an open distal end of the shaft.

7. The device of claim 5, wherein the tissue-penetrating tip is rotatable relative to the shaft.

8. The device of claim 5, wherein the tissue-penetrating tip has a closed distal-most end.

9. The device of claim 1, wherein each of the anchors is loaded in one of the plurality of channels.

10. The device of claim 9, wherein each of the sutures has a pushable knot formed thereon.

11. The device of claim 1, wherein the shaft is flexible such that the shaft can be passed through a tortuous pathway.

12. The device of claim 1, further comprising a plurality of suture channels formed in the shaft configured to seat the sutures extending from the suture anchors, the plurality of suture channels being axially aligned with the plurality of channels.

13. The device of claim 1, wherein each of the anchors is configured to be deployed independent of a remainder of the anchors seated in the channels such that the anchors can be deployed sequentially from the shaft.

14. The device of claim 13, wherein the anchors are configured to be deployed simultaneously from the shaft.

15. The device of claim 1, wherein the plurality of channels are located entirely in a distal portion of the device.

16. The device of claim 1, wherein each of the plurality of channels has an open end and a closed end.

17. A surgical device, comprising:

an elongate flexible shaft having proximal and distal ends;

a handle at the proximal end of the elongate shaft; and

a plurality of suture anchors disposed within a distal portion of the shaft, each suture anchor having a length of suture extending therefrom, each of the plurality of suture anchors being configured to be deployed from the shaft through a sidewall of the shaft, and each of the plurality of anchors being configured to be pulled proximally relative to the shaft to be deployed from the shaft through the sidewall of the shaft independent of a remainder of the anchors such that the anchors can be deployed sequentially from the shaft through the sidewall of the shaft,

wherein each suture is configured to be pulled to deploy one of the plurality of suture anchors coupled thereto,

wherein each suture extends through a suture channel formed in the shaft, and

wherein a plurality of channels are formed in the elongate shaft each configured to seat one of the plurality of anchors, each of the plurality of channels having an open end and a closed end, where each of the plurality of channels are isolated from the suture channel.

18. The device of claim 17, wherein the sidewall of the shaft has a plurality of openings, each of the plurality of suture anchors being configured to be deployed through one of the plurality of openings.

19. The device of claim 17, further comprising a penetrating element movable through the shaft and having a tissue-penetrating tip rotatable relative to the shaft for penetrating tissue.

20. The device of claim 17, wherein the plurality of anchors are configured to be deployed simultaneously from the shaft.

21. The device of claim 17, wherein the elongate shaft has a tissue-penetrating tip at the distal end thereof.

22. The device of claim 17, wherein each of the plurality of anchors are configured to be pulled proximally relative to the shaft by pulling proximally the length of suture coupled thereto.
