Abstract
Driver assemblies are configured to protect a threaded sleeve of an anchor from damage due to over-insertion. An internal spring permits axial retraction of an outer shaft coupled to the sleeve independent of the inner shaft and the handle. Connection members extending along the spring create an axial stop between a drive housing and a center housing of the driver assembly. The drive housing is allowed to travel proximally in response to axial loading against the spring, while travel distally is limited by the engagement between the connection members and receivers on the center housing.
