The insertion instrument can include a single cannula that retains the pair of anchor bodies in a stacked relationship, or a pair of adjacent cannulas that each retain a corresponding anchor body. The insertion instrument can be actuated so as to eject the anchor bodies into respective target anatomical locations.SELECTED DRAWING: Figure 7A |
