20090088851 | COMBINATION PLATE AND DISC PROSTHESIS - Orthopedic medical devices for use in orthopedic procedures are provided, having in certain embodiments a first member and a second member configured to replace a disk between a first vertebra and a second vertebra. Additionally, the second member is also configured to fuse the second vertebra to at least a third vertebra. In one embodiment, the second member has a first portion that is elastic and a second portion that is substantially rigid. In other embodiments, the second member is substantially rigid. In yet another embodiment, the first member and second member are configured to replace a disk between the first vertebra and the second vertebra, and the second member and a third member are configured to replace a second disk between the third vertebra and a fourth vertebra. In this embodiment, the first, second, and third members may be connected to vertebrae by various anchors. | 04-02-2009 |
20120197401 | INTERBODY SPINAL IMPLANTS WITH MODULAR ADD-ON DEVICES - An implant assembly for a spinal column includes at least an interbody element and an add-on element that is removably attachable to the add-on element to form an implant assembly. At least a portion of the add-on element is positionable in a space between vertebrae along with the interbody element to support the vertebrae. | 08-02-2012 |
20120197402 | INTERVERTEBRAL IMPLANT WITH ROTATING MEMBER - An implant for spacing apart skeletal structures. The implant includes a base, a rotatable member, and a connector. The base extends around at least a portion of the member, and the member is pivotally connected to the base by the connector. The member includes a first pair of opposing sides that have a first height that is smaller than or equal to a height of the base, and a second pair of opposing sides that have a second height larger than the base. The member is movable to a first rotational position with the first pair of opposing sides facing in the same direction as the sides of the base such that the member is shorter than or equal to the base. The member is also movable to a second rotational position with the second pair of opposing sides facing in the same direction as the sides of the base such that the member is taller than the base. | 08-02-2012 |
20120259416 | LATERALLY EXPANDABLE INTERBODY SPINAL FUSION IMPLANT - A spinal implant particularly adapted for lateral expansion while disposed in the disc space between adjacent vertebrae. The implant includes a first frame member pivotally linked to a second frame member via at least one, and preferably multiple, pivoting links. The implant may be inserted into the disc space in a collapsed configuration using a lateral approach, and then expanded in the anterior-posterior direction (lateral to insertion direction) to a deployed configuration where the first and second frame members are farther apart. The implant may be expanded by holding one frame member and pushing on the other frame member or one or more proximal links linking the two frame members. | 10-11-2012 |

20090203967 | Instruments and methods for minimally invasive tissue retraction and surgery - Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. Instruments are engageable to the first and second portions and operable to move the first and second portions relative to one another. | 08-13-2009 |
20130231708 | Bone Screw - A bone screw and method of inserting a bone screw into a bone is disclosed. In one example, the bone screw includes a tip segment for creating a starter hole in the bone. A pilot segment is located proximally of the tip segment for creating a pilot hole in the bone after creation of the starter hole. A threaded segment is located proximally of the pilot segment for fixedly securing the bone screw in the bone. A head is located proximally of the threaded segment for allowing a surgical rod to be fixedly secured to the bone screw. | 09-05-2013 |
20140094858 | MULTI-ROD BONE ATTACHMENT MEMBER - A fixation element for use in orthopedic surgery, particularly spinal surgery is disclosed. The fixation element is capable of being screwed, hooked, or otherwise attached to a bone, and is configured to accommodate two or more rods or other elongated members. The head of the fixation elements thus has multiple places for positioning a rod, either vertically or horizontally spaced from each other. | 04-03-2014 |
20140135796 | Trajectory Storage Apparatus and Method for Surgical Navigation Systems - A method and apparatus for determining, calculating, and/or viewing a trajectory. The trajectory can be displayed on a display relative to image data of a patient. A user can use the system to determine relationships between two or more trajectories that have been determined. The relationships can be within two dimensional, three-dimensional, or four dimensional space. The relationships can include distance, angle, etc. The relationships can also be determined between real time trajectories and stored trajectories, or combinations thereof. | 05-15-2014 |
