Abstract

Devices for dispensing suture threads and/or suture threads with needles attached to them that are particularly useful for inserting surgical implants, such as suture anchors, that make use of sutures. The devices use a novel spool design to safely and neatly hold the suture thread and/or needles until the surgeon wishes to dispense them.
