A soft tissue repair device can include a housing having a handle, a deployment system having an actuation member, and an insertion system having an inserter and a slider. The slider can be coupled to the actuation member and movable relative to the inserter between deployed and retracted positions.
A soft tissue repair device can include a housing having a handle, a deployment system having an actuation member, and an insertion system having an inserter and a slider. The slider can be coupled to the actuation member and movable relative to the inserter between deployed and retracted positions. First and second anchors can be carried on an external surface of the slider such that the anchors are spaced apart and portions of the anchors are coaxial with the slider and each other. A flexible strand can couple the anchors. The insertion system can cooperate with the deployment system to move the slider to the deployed position to deploy the first anchor upon activating the actuation member a first time, and to move the slider to the deployed position from the retracted position to deploy the second anchor upon actuating the actuation member a second time after the first time.

The method of claim 5, wherein the first and second flexible anchors are loaded in a substantially linear first shape on an external surface of the slider; and wherein tensioning the flexible strand comprises changing the shape of each flexible anchor from the first shape to a second deformed shape that is suitable for securing each flexible anchor to the external surface of the soft tissue. 7. The method of claim 2, wherein the first and second coupled anchors are loaded on the external surface of the slider with only a portion of the internal bores of the first and second coupled anchors positioned over the external surface of the slider such that a first portion of each anchor is coaxial with the slider and a second tail portion of each anchor extends at an angle relative to the slider, and wherein the second tail portion is configured to engage the external surface of the soft tissue when the actuation member is released and the slider is retracted from being translated beyond the distal end of the inserter. 8. The method of claim 1, wherein providing or obtaining an insertion device further includes providing or obtaining an insertion device with an outer cannula having a distal end extending from the housing and a proximal end coupled to an adjustment mechanism, the slider and the inserter being positioned in a longitudinal passage extending through the outer cannula. 9. The method of claim 8, further comprising adjusting a distal end of the outer cannula relative to the distal end of the inserter such that the distal end of the inserter extends beyond the distal end of the outer cannula so as to establish an insertion depth of the inserter. 10. The method of claim 1, wherein actuating an actuation member at a first time comprises translating a positioning member disposed coaxially around the slider and inside the inserter to translate the second anchor forward towards the distal end of the inserter. 11. The method of claim 10, wherein releasing the actuation member comprises retracting the slider to a retracted position such that an engagement portion of the slider is positioned adjacent to or beyond the translated second anchor; and wherein actuating the actuation member a second time includes depressing the actuation member a second time after releasing the actuation member and translating the second anchor to the third position such that the engagement portion of the slider engages the second anchor and moves the second anchor beyond the distal end of the inserter. 12. The method of claim 1, wherein the first and second coupled anchors are longitudinally spaced from one another along the slider when deploying the first anchor from the slider. 13. A method for repairing a tear in soft tissue, comprising: adjusting a position of a distal end of an outer cannula relative to a distal end of an inserter;inserting the distal end of the inserter into soft tissue and through the soft tissue to a first location along an exterior surface of the soft tissue, wherein during said inserting a first anchor and a slider carrying the first anchor are situated in the inserter;actuating an actuation member at a first time to translate a distal end of the slider beyond the distal end of the inserter, wherein, during said actuating, the slider is extending through a portion of the first anchor such that advancement of the slider through the inserter advances the first anchor through the inserter;deploying the first anchor from the slider to deliver the first anchor to the first location along the exterior surface of the soft tissue; andremoving the inserter from the soft tissue. 14. The method of claim 13, further comprising: releasing the actuation member after deploying the first anchor;retracting the slider to a retracted position such that an engagement portion of the slider is positioned adjacent to a translated second anchor;inserting the distal end of the inserter into the soft tissue for a second time and through the soft tissue to a second location along the exterior surface of the soft tissue; andactuating the actuation member at a second time to deploy the second anchor upon the engagement portion of the slider engaging the second anchor and moving the second anchor beyond the distal end of the inserter to deliver the second anchor to the second location along the exterior surface of the soft tissue. 15.
