1. A method for repairing a defect in soft tissue comprising:
- positioning a tissue repair device having an inserter and a cannula adjacent to the defect in the soft tissue;
determining a depth of a distal end of the inserter to extend beyond a distal end of the cannula;
providing a depth limiter separate from the inserter and separate from the cannula;
installing the depth limiter over a shaft of the inserter between a handle of the inserter and a handle of the cannula for controlling the depth of the distal end of the inserter relative to the distal end of the cannula to the determined depth;
extending the distal end of the inserter beyond the distal end of the cannula to the determined depth; and
passing the distal end of the inserter into the soft tissue from a first side of the defect to a second side of the soft tissue until at least a portion of the distal end of the inserter exits the second side of the soft tissue, wherein an anchor carried on the distal end of the inserter is passed from the first side of the defect to the second side of the soft tissue.

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.

11. A method for repairing a defect in soft tissue comprising:
-
passing a distal end of a first inserter that carries a first anchor between a buttress and a distal piercing end of the first inserter into and through the soft tissue; deploying the first anchor from the first inserter at a first location relative to the defect; passing a distal end of a second inserter that carries a second anchor between a buttress and a distal end of the second inserter into and through the soft tissue; deploying the second anchor from the second inserter at a second location relative to the defect; and tensioning a flexible strand that couples the first anchor to the second anchor so as to compress the defect, wherein the first anchor and the second anchor each comprise a flexible tube received on the flexible strand, wherein the flexible strand provides a self-locking adjustable knotless loop, and 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 the self-locking adjustable knotless loop. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for repairing a tear in a meniscus comprising:
-
advancing a first anchor carried on a distal end of a first inserter between a buttress and a distal piercing end of the first inserter out a distal end of a cannula; pushing the first anchor through the meniscus with the first inserter; retracting the first inserter into the cannula to deploy the first anchor at a first location on the meniscus; advancing a second anchor carried on a distal end of a second inserter between a buttress and a distal piercing end of the second inserter out the distal end of the cannula; pushing the second anchor through the meniscus with the second inserter; retracting the second inserter into the cannula to deploy the second anchor at a second location on the meniscus; and tensioning a flexible strand that couples the first anchor to the second anchor so as to repair the tear in the meniscus, wherein the flexible strand provides a self-locking adjustable knotless loop, the flexible strand extending into an internal passage of the flexible strand at a first aperture, extending along the internal passage of the flexible strand and out of the flexible strand at a second aperture in the flexible strand to form the self-locking adjustable knotless loop, wherein the first anchor is positioned proximal of the distal piercing end of the first inserter without the first inserter penetrating the first anchor, and wherein the second anchor is positioned proximal of the distal piercing end of the second inserter without the second inserter penetrating the second anchor. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
