Patent number: 9060757Abstract: An instrument for distracting and/or compressing adjacent vertebrae is described. The instrument includes a yoke, a first blade movably mounted to the yoke, a second blade mounted to the yoke and an adjustment system. The yoke, the first blade and the second blade form a working channel for the instrument.

Publication number: 20120232533Abstract: An elongate member having a fixed end is passed through a plurality of grippers that impart tension in the elongate member and prevent the tension from being released. At least one gripper is movable while at least one other can be fixed. The movable gripper travels along the elongate member toward the fixed end then reverses direction, grips the elongate member, and carries the elongate member away from the fixed end, thereby creating tension in the elongate member. At least one gripper prevents the tension from being released. In some embodiments, the elongate member passes through a rotatable shaft with a lumen. The shaft can be in communication with a crank, whereby operation of the crank rotates the shaft.Type: ApplicationFiled: December 1, 2010Publication date: September 13, 2012Applicant: SONOMA ORTHOPEDIC PRODUCTS, INC.Inventors: Michael Scott Veldman, Jeffrey Warren Beale, Robert H.

Patent number: 8118849Abstract: A screw assembly (10) for insertion into a bone region (12A) (12B) includes a screw body (14) and a washer (16). The screw body (14) includes a distal end (218), a proximal end (224), and a distal threaded area (220), and a proximal threaded area (226). The distal threaded area (220) is positioned near the distal end (218) and the proximal threaded area (226) is positioned near the proximal end (224). The washer (16) includes a washer threaded area (238) that engages the proximal threaded area (226) to selectively secure the washer (16) to the screw body (14). With this design, the washer (16) can be selectively attached to the screw body (14) and different sized washers (16) can be alternatively and selectively secured to the screw body (14). As a result thereof, the person inserting the screw assembly (10) can pick the washer (16) size best suited to retain the bone region (12A) (12B) in which the screw assembly (10) is being inserted.Type: GrantFiled: March 15, 2007Date of Patent: February 21, 2012Assignee: Tornier, Inc.Inventors: Rebecca Hawkins Wahl, Hanspeter Robert Bayer, Ronald George Litke, Jr., Scott W.
