Abstract
Fixation device cartridges. At least one example embodiment is a cartridge including: a first tube; a second tube parallel to first tube; a first spacer coupled to the first tube and the second tube such that slots of the first and second tubes face each other; a second spacer coupled to the first tube and the second tube, the first and second spacers defining a suture volume between the slots of the first and second tubes, and the slot of the first tube and the slot of the second tube open into the suture volume; a first bone anchor disposed within the first tube, a first suture line associated with the first bone anchor and extending through the slot; and a second bone anchor disposed within the second tube and coupled to the first suture line.
