Abstract

Meniscal repair devices, systems, and methods are provided.

First claim

What is claimed is:

1. A surgical system, comprising:
an implant having an open proximal end and having an external thread;
a driver including a distal portion configured to extend through the open proximal end of the implant to mate the implant to the driver, the driver being configured to rotate to drive the implant when mated thereto through tissue to move the implant from being located entirely within a first cavity on one side of a tissue to being located entirely within a second cavity on an opposite side of the tissue, and the driver being configured to be withdrawn from the implant to leave the implant entirely within the second cavity;
a first suture attached to the implant, the first suture including a noose; and
a second suture including a knot coupled to the noose at a swivel coupling that couples the first and second sutures together, the swivel coupling being configured to allow the driver to rotate the implant and the first suture relative to the second suture.

2. The system of claim 1 , wherein the implant has a pointed distal tip and is non cannulated.

3. The system of claim 1 , wherein the implant has an inner lumen extending therethrough such that the implant is cannulated, and the driver has a pointed distal tip that is located distal to the implant when the implant is mated to the driver.

4. The system of claim 1 , wherein the second suture is configured to extend from the first cavity to the second cavity in response to the implant being moved to the second cavity.

5. The system of claim 4 , further comprising a second implant having the second suture coupled thereto, the rotation of the driver to drive the implant not rotating the second implant.

6. A surgical system, comprising:
an implant having a distal end, a proximal end, an indented intermediate portion located between the distal and proximal ends and extending circumferentially around the implant, a first external thread located entirely between the proximal end and the indented intermediate portion, and a second external thread located entirely between the proximal end and the indented intermediate portion; and
a collapsible suture seated in the indented intermediate portion and configured to be collapsed so as to cinch the suture around the implant;
wherein the intermediate portion is defined by a ring of material attaching together proximal and distal rigid portions of the implant;
the ring of material is configured to flex radially inward in response to tension of the suture therearound;
the first external thread is located in the proximal rigid portion; and
the second external thread is located in the distal rigid portion.

7. The system of claim 6 , wherein the proximal end is open;
the system further comprises a driver including a distal portion configured to extend through the open proximal end of the implant to mate the implant to the driver, the driver being configured to, with the distal portion of the driver extending through the open proximal end of the implant rotate to drive the implant through tissue; and
the rotation of the driver is configured to rotate the implant relative to the suture seated in the indented intermediate portion.

8. The system of claim 7 , further comprising a second implant having the suture coupled thereto;
wherein the rotation of the driver to rotate the implant does not rotate the second implant.

9. A surgical system, comprising:
an implant having a distal end, a proximal end, an indented intermediate portion located between the distal and proximal ends and extending circumferentially around the implant, a first external thread located entirely between the proximal end and the indented intermediate portion, and a second external thread located entirely between the proximal end and the indented intermediate portion; and
a collapsible suture seated in the indented intermediate portion and configured to be collapsed so as to cinch the suture around the implant;
wherein the intermediate portion is defined by a plurality of fabric strips extending between proximal and distal rigid portions of the implant;
the first external thread is located in the proximal rigid portion; and
the second external thread is located in the distal rigid portion.

10. The system of claim 6 , wherein the intermediate portion is unthreaded.

11. The system of claim 6 , wherein the proximal end is open; and
an internal bore extends distally in the implant from the open proximal end of the implant and terminates proximal to the intermediate portion.

12. The system of claim 6 , wherein the proximal end is open, and the distal end is open.

13. The system of claim 6 , wherein the collapsible suture seated in the indented intermediate portion is configured to be collapsed so as to cinch the suture around an entire circumference of the implant.
