Patent number: 8460309Abstract: An inserter for inserting a suture anchor into bone. The inserter has external markings that uniquely identify the orientations and the relative longitudinal positions of at least two suture passages through a suture anchor releasably engaged with the inserter. The markings assist a surgeon in determining a preferred placement and orientation of the anchor at an operative site during a surgical procedure.Type: GrantFiled: March 4, 2011Date of Patent: June 11, 2013Assignee: DePuy Mitek, LLCInventor: Jonathan Howe

Patent number: 8449584Abstract: A bone anchor is provided that can toggle in two planes for secure anchorage within a bone cavity. The bone anchor includes an oblique suture channel configured such that a suture strand extending through the bone anchor can be tensioned to toggle the bone anchor inside the bone cavity. The suture strand can be located on the same side of the anchor body to maximize the area of the anchor surface which engages bone, resulting in increased engagement into bone and resistance to tensile forces.Type: GrantFiled: December 15, 2010Date of Patent: May 28, 2013Assignee: DePuy Mitek, LLCInventors: Lisa M. Donnelly, Edwin C. Bartlett, Karl S. Reese, Steven D. Muller, Paul J. Ares

Patent number: 8317863Abstract: A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.Type: GrantFiled: March 3, 2010Date of Patent: November 27, 2012Assignee: DePuy Mitek, LLCInventors: Nathan Cauldwell, Lisa M.
