Abstract
Abstract An anchor and anchor driver device for securely and accurately positioning and installing a bone (suture) anchor in place are disclosed. The bone anchor has a rounded or pointed head and a series of ridges around it which are used to help force fit the anchor into a hole and to hold it in place. A suture is positioned through the anchor for subsequent use during the surgical procedure. The driver device has a handle and elongated shaft and is used to position and install the anchor in place. The anchor snap fits onto the end of the shaft over an anti-rotation pin which mates with slots in the anchor. The ends of the suture are affixed to the driver handle. Means are provided on the driver to prevent the suture from interfering with the positioning and installation procedure.
