A cylindrical first anchor can be disposed in the bore proximal to a distal end of the bore. A cylindrical second anchor can be disposed in the bore proximal to the first anchor. A pusher wire can include teeth positioned at a distal end of the pusher wire. The pusher wire and teeth can be configured to engage an interior of the first anchor; advance distally, with respect to the needle, to force the first anchor distally out of the bore; retract proximally, with respect to the needle and the second anchor, to position the teeth inside an interior of the second anchor; engage the interior of the second anchor; and advance distally, with respect to the needle, to force the second anchor distally out of the bore. ## Claims ### Claim 1 A repair device, comprising: a needle defining a bore extending through a distal end of the needle; a deformable cylindrical first anchor sized and shaped to be disposed in the bore proximal to a distal end of the bore; a deformable cylindrical second anchor sized and shaped to be disposed in the bore proximal to the first anchor; and a pusher wire including teeth positioned at a distal end of the pusher wire, the teeth configured to: be positioned entirely within an interior of the deformable cylindrical first anchor; be advanced distally with respect to the needle while remaining entirely within the interior of the deformable cylindrical first anchor to force the deformable cylindrical first anchor distally out of the bore through engagement of the teeth with the interior of the deformable cylindrical first anchor; be retracted proximally, with respect to the needle and the deformable cylindrical second anchor, to position the teeth entirely within an interior of the deformable cylindrical second anchor; and be advanced distally with respect to the needle while remaining entirely within the interior of the deformable cylindrical second anchor to force the deformable cylindrical second anchor distally out of the bore through engagement of the teeth with the interior of the deformable cylindrical second anchor. ### Claim 2 (depends on 1) The repair device of claim 1, wherein the teeth are sized and shaped to: catch on the interiors of the deformable cylindrical first and second anchors when the pusher wire and teeth are advanced distally with respect to the deformable cylindrical first and second anchors, respectively; and slide along the interiors of the deformable cylindrical first and second anchors when the pusher wire and teeth are retracted proximally with respect to the deformable cylindrical first and second anchors, respectively. ### Claim 3 (depends on 1) The repair device of claim 1, wherein the pusher wire has an outer diameter smaller than the inner diameters of the deformable cylindrical first and second anchors, so that the pusher wire is slidable through the deformable cylindrical first and second anchors in the proximal and distal directions. ### Claim 4 (depends on 1) The repair device of claim 1 further comprising a tube pusher positioned over the pusher wire within the bore of the needle, the tube pusher having a distal portion that extends radially beyond an outer circumference of the second anchor, so that the tube pusher pushes the second anchor distally as the tube pusher advances distally within the bore of the needle. ### Claim 5 (depends on 1) The repair device of claim 1 further comprising: a handle fixedly coupled to a proximal end of the needle, and a push button disposed on an exterior of the handle, the push button being slidable proximally and distally with respect to the handle between a first proximal position and a first distal position, the push button being coupled to the pusher wire so that proximal and distal movement of the push button produces proximal and distal movement of the pusher wire and teeth. ### Claim 6 (depends on 5) The repair device of claim 5, further comprising an adjustable depth stop assembly configured so that movement of the push button to the first distal position distally advances the teeth to a selectable distance beyond a distal end of the needle. ### Claim 7 (depends on 6) The repair device of claim 6, wherein the handle is configured to emit an audible click when the push button reaches the first distal position on the handle. ### Claim 8 (depends on 5) The repair device of claim 5, wherein the teeth are positioned within the deformable cylindrical first or second anchors when the push button is positioned at the first proximal position. ### Claim 9 (depends on 8) The repair device of claim 8, wherein the handle is configured to emit an audible click when the push button reaches the first proximal position on the handle. ### Claim 10 (depends on 8) The repair device of claim 8 further comprising a tube pusher positioned over the pusher wire within the bore of the needle, the tube pusher having a distal portion that extends radially beyond an outer circumference of the second anchor, so that the tube pusher pushes the second anchor distally as the tube pusher advances distally within the bore of the needle, wherein proximal motion of the push button does not move the tube pusher proximally. ### Claim 11 (depends on 10) The repair device of claim 10, wherein distal motion of the push button advances the tube pusher distally. ### Claim 12 (depends on 8) The repair device of claim 8, wherein: the teeth are positioned within the deformable cylindrical first anchor when the push button is positioned at the first proximal position; and the teeth are positioned within the deformable cylindrical second anchor when the push button is positioned at the second proximal position. ### Claim 13 (depends on 12) The repair device of claim 12, wherein the handle is configured to emit an audible click when the push button reaches the second proximal position on the handle. ### Claim 14 (depends on 12) The repair device of claim 12 further comprising a tube pusher positioned over the pusher wire within the bore of the needle, the tube pusher having a distal portion that extends radially beyond an outer circumference of the second anchor, so that the tube pusher pushes the second anchor distally as the tube pusher advances distally within the bore of the needle, wherein proximal or distal motion of the push button does not move the tube pusher proximally or distally. ### Claim 15 (depends on 1) The repair device of claim 1, wherein the deformable cylindrical first and second anchors are connected by an adjustable suture loop. ### Claim 16 A repair device, comprising: a needle defining a bore extending through a distal end of the needle;
