A suture holder delivery system including a housing having a distal end and a proximal end, a first driver mechanism and a second driver mechanism, each movable in a longitudinal direction with respect to the housing, a first delivery needle and a second delivery needle, the first delivery needle connected at a proximal end to the first driver mechanism and the second delivery needle connected at a proximal end to the second driver mechanism, the first driver mechanism and said second driver mechanism each having fully retracted and fully extended positions and a toggle assembly operable to fix at least one of the first driver mechanism and second driver mechanism in at least one longitudinal position. The delivery system may include a locking mechanism operable to prevent the second driver mechanism from being moved in a distal direction until the first driver mechanism is longitudinally advanced to the extended position. |

1. A suture anchor delivery system, comprising:
a housing having a distal end and a proximal end; a first longitudinal channel and a second longitudinal channel disposed within the housing, the first longitudinal channel and the second longitudinal channel being adjacent to one another and open to a top surface of the housing; a bore disposed within the housing and extending in a lateral direction between the first longitudinal channel and the second longitudinal channel; a first driver and a second driver, each movable in a distal direction toward said distal end of said housing, from a respective fully retracted position to a respective fully extended position, the first driver being disposed in the first longitudinal channel and the second driver being disposed in the second longitudinal channel; a first delivery needle and a second delivery needle, said first delivery needle connected at a proximal end to said first driver and said second delivery needle connected at a proximal end to said second driver; a control operable to prevent said second driver from being moved in the distal direction from its respective fully retracted position toward its respective fully extended position until said first driver is moved in the distal direction to its respective fully extended position; wherein said control includes a first pin, the first pin having a pin body slidable in the lateral direction within the bore between a locked position and an unlocked position, wherein said pin body is in the locked position until the first driver is moved in the distal direction to its respective fully extended position, and is in the unlocked position after the first driver is moved in the distal direction to its respective fully extended position. |
