Abstract

A fibrous tissue repair device includes first and second tubular anchors having corresponding longitudinal passages. The tissue repair device includes corresponding first and second inserters. Each inserter has a shaft with a distal portion received in the longitudinal passage of the corresponding tubular anchor. A flexible strand couples the first and second anchors.

4. The repair device of claim 1, wherein the flexible strand is formed as a self-locking adjustable knotless loop.

5. The repair device of claim 1, further comprising a slider control mechanism configured to prioritize separate deployment of the first inserter and the second inserter.

6. The repair device of claim 1, wherein the first anchor is in a folded configuration on the distal outer surface of the first inserter.

7. The repair device of claim 1, wherein the flexible strand extends into an internal passage of the flexible strand at a first aperture, extends along the internal passage of the flexible strand and out of the flexible strand at a second aperture in the flexible strand to form a self-locking adjustable loop.

8. The repair device of claim 1, wherein the first anchor is positioned proximal of the tissue-piercing distal end of the first inserter without the first inserter penetrating the first anchor.

9. The repair device of claim 1, wherein the first inserter and the second inserter are both unitary one-piece inserters.

10. A tissue repair device comprising:

a handle;

a first inserter extending from and movable relative to the handle;

a second inserter extending from and movable relative to the handle;

a first slider configured to move the first inserter;

a second slider configured to move the second inserter;

a first anchor carried on a first distal end of the first inserter;

a second anchor carried on a second distal end of the second inserter; and

a slider control mechanism configured to prioritize separate deployment of the first inserter relative to the second inserter, wherein the slider control mechanism is configured to enable a forward deployment motion of the first inserter before enabling a retraction motion of the first inserter and a subsequent forward deployment motion of the second inserter, and wherein the slider control mechanism includes a disc having a first side and a second side where the first side includes a first post and a second post and the second side includes a third post, the handle defining a first track, a second track and a third track, each track configured to receive the first, second and third post, respectively, to prioritize separate deployment of the first inserter relative to the second inserter.

11. The repair device of claim 10, wherein the first anchor and the second anchor are coupled together with a flexible strand formed as a self-locking adjustable knotless loop.

12. The repair device of claim 11, wherein the first anchor and the second anchor are slidable along the flexible strand.
