An anchor insertion instrument for closing an annulus defect after a microdiscectomy technique is provided. An insertion instrument is configured to discharge a pair of anchor bodies across an anatomical gap to narrow the gap. The insertion instrument can have one cannula that holds a pair of anchor bodies in a stacked relationship, or a pair of adjacent cannulas, each holding each anchor body. The insertion instrument can be actuated to eject the anchor body to each target anatomical location. [Selection] Figure 7A |
