lt Apparatus and method for sequentially anchoring multiple graft ligaments in a bone tunnel By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen. The sleeve is configured for at least partial insertion into the bone tunnel with each graft ligament positioned laterally adjacent a different ligament-contacting surface and at least partially located between the bone tunnel and the sleeve. An actuating member has proximal and distal actuating member ends. An asymmetrically offset profile is defined by the sleeve and/or the actuating member. The asymmetrically offset profile has engagement thresholds. The actuating member is inserted into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface, the frictional engagement of each graft ligament being temporally spaced apart from the frictional engagement of at least one other graft ligament.

lt Multi-spindle milling By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT A milling apparatus is provided for cutting desired contours into a workpiece. The apparatus comprises a head that moves relative to a workpiece in a direction of cut. Spindles are supported on the head for rotation about parallel spaced-apart spindle z axes and comprise respective rotary cutters adapted for use in machining operations. A rotary head positioner is configured to be operatively connected between the head and a milling machine and to rotate the head about a head axis. A stagger controller is connected to the rotary head positioner and is configured to provide a desired swath of a cut to be formed in a workpiece by rotating the head to set a corresponding spindle stagger angle value.
