Abstract

A suture/anchor and delivery device combination includes a first cannulated suture and a second stepped or staged suture that has a smaller diameter section connected to a larger diameter section. The smaller diameter of the second suture is passed through the first suture and the assemblage of sutures is further passed through a tube which acts as an inserter. To actuate the device, the larger diameter of the second suture is pulled into the lumen of the first suture, thereby expanding the first diameter of the first suture to create an interference fixation within bone.
