  • Patent number: 8414623
    Abstract: A connector for connecting together elongated members in a side-by-side arrangement. The connector includes a first receptacle for connecting to the first elongated member, and a second receptacle for connecting to the second elongated member. The angular position of the second receptacle may be adjustable relative to the first receptacle to accommodate the elongated members. Further, the connector may be configured to extend between the elongated members and the patient when the connector is implanted in a patient.

  • Patent number: 8317834
    Abstract: Surgical constructs pre-assembled for insertion as a unit into a patient. The pre-assembled construct may include an elongated member with opposing first and second ends. The construct may also include a connector with a body, a first receptacle that extends through the body and receives the elongated member, a threaded aperture that extends from an exterior of the body into the first receptacle, a fastener threaded into the threaded aperture, and a second receptacle that receives a structural member in the patient. The first receptacle may be larger than the elongated member for the connector to be movable along the elongated member. The construct may also include retaining members permanently attached to each of the first and second ends of the elongated member. The retaining members may include a central opening with an inner radial surface that contacts the elongated member and an outer radial surface that extends outward beyond the elongated member.

  • Patent number: 8128665
    Abstract: Apparatuses are disclosed for use in orthopedic surgery, for example for procedures in which a support member is connected to the spine. A connector member for connecting to an orthopedic implant and a support member is provided. A sleeve fits around the implant, and a locking member or mechanism connects to the sleeve. Locking causes a part of the sleeve to press the support against the connector, and causes a part of the sleeve to compress around the implant, so that the implant and support are substantially inhibited or prevented from moving with respect to each other.

  • Publication number: 20120035667
    Abstract: Bone anchors are provided that include a distal shaft for engaging bony structure of a vertebral body and a proximal post pivotably mounted at or near the proximal end of the shaft during implantation of the bone anchor. The bone anchors include a locking member that is engageable to the post and to the shaft to lock the post in a selected angular orientation relative to the shaft.

  • Publication number: 20090264926
    Abstract: Embodiments of a spinal implant system include a fixation element, a connector body, and a compression member. The fixation element has a bone engaging portion, a pivoting portion, and a hinge portion. The hinge portion permits pivotal motion of the pivoting portion relative to the bone engaging portion. Additionally, the connector body defines a channel configured for receipt of an elongate member and defines an elongate slot configured for receipt of the pivoting portion of the fixation element. The pivoting portion is positionable in any one of a plurality of positions along the elongate slot. The compression member is adapted to engage the pivoting portion of the fixation element and press against the connector body to lock the pivoting portion at a desired angular position relative to the bone engaging portion and lock the connector body to the fixation element at the desired position along the elongate slot.

  • Patent number: 7578822
    Abstract: An apparatus for use in orthopedic distraction or compression is disclosed. In the illustrated embodiments, two arms are provided that are connected by a rod or bar with a mechanism that enables the arms to be brought toward or away from each other. At the end of each arm, an assembly for connecting to a bone implant is provided. The assemblies are pivotable with respect to the arms, and allow some rotational motion between parts of the assembly so as to accommodate different positions of the bone implants. Once the assemblies are appropriately positioned, connected and locked to the bone implants, the mechanism can be operated to move the arms together in compression or apart in distraction.

  • Patent number: 7270665
    Abstract: A bone fixation system for locking a longitudinal member, such as a spinal rod, to a bone anchor element allowing a variable orientation of the axis of the longitudinal member relative to the axis of the bone anchor. A one-piece body element split along a substantially horizontal plane into upper and lower portions by a slot includes a ball element through which a longitudinal member, such as a spinal rod, may pass. A portion of a bone anchor element passes through an aperture having portions on each of the upper and lower portions of the body element. Tightening a set screw draws the upper and lower portions of the body element together and locks the bone anchor and spinal rod into the desired position.

  • Patent number: 6556857
    Abstract: A trackable medical instrument includes a guide member and an emitter array coupled to the guide member. A drive shaft is rotatably coupled to the guide member, and a locking mechanism is provided along the drive shaft. The emitter array emits a signal that is used to track the position of the guide member. The locking mechanism has an unlocked position in which the drive shaft rotates relative to the guide member. The locking mechanism also has a locked position in which the drive shaft is rotationally stationary relative to the guide member. A processor tracks medical instruments using a sensor array and a reference array. A display that is operatively coupled to the processor displays the position of the instrument in relation to a patient.
