Abstract: A transverse connector system for interconnecting two spinal rods includes a connector arranged to span the distance between the rods with a rod receiving recess and a pin receiving bore on each end. A one-piece pin member such as a set screw is disposed within each bore with an enlarged head protruding from the bottom of the connector so that when the set screw is retracted into the bore the head engages a side of the respective rod to clamp the rod within the recess. The connector may comprise two elongated members with a recess and pin receiving bore at one end of each member, a middle coupler which allows three degrees of freedom between the members to accommodate any anticipated spatial orientation between the members and a set screw for securing the other ends of the members together.

Abstract: An anchoring device for attaching an upper vertebra adjacent to a lower vertebra comprises a clamp having a first end and a second end opposite the first end, adapted to be positioned around upper and lower lateral masses of the adjacent vertebrae, and a fastener which in an installed position engages opposite ends of the clamp and which engages adjacent vertebrae thereby attaching the adjacent vertebrae together.

Abstract: A spinal fixation device and method including at least one longitudinal rod mounted substantially parallel to the axis of the spine and having a plurality of stem clamps adjustably mounted to the longitudinal rod. Each stem clamp has a stem extending outwardly therefrom with the diameter of the stem being identical to the diameter of the longitudinal rod. A plurality of C-clamps are provided and are mounted to the stems and to the longitudinal rods. Each C-clamp includes a female-tapered through-passage for matingly engaging a male tapered head of a pedicle screw. A plurality of pedicle screws are used to simultaneously anchor the C-clamps to the bone and to the respective stem and longitudinal rod.

Abstract: A spinal rod system includes a first rod and a second rod engaged to a connector with the first and second rods extending axially therefrom in opposite direction and in laterally offset relation. The connector includes first and second side-by-side receptacles for receiving respective ones of the rods. The connector includes a clamping arrangement to releasably secure the rods in the respective receptacles. The receptacles allow the relative axial position between the rods to be adjusted to accommodate anatomical conditions.

Abstract: A system for connecting a spinal osteosynthesis rod and a crossbar include a passage for receiving the crossbar and hinge mounted jaws for clamping the rod. A locking device biases the crossbar against the jaws. A return spring pulls the jaws relatively close to one another independently of the crossbar such that the jaws may clamp the osteosynthesis rod to ensure a stable mounting of the connection system to the osteosynthesis rod.

Abstract: A cross connector that can be used with a spinal implant includes a first rod clamp having a first end and an opposing second end, the first rod clamp having a first clamp arm crossing a second clamp arm so as to form a scissor coupling. The cross connector also includes a second rod clamp and a cross bar assembly extending between the first rod clamp and the second rod clamp.

Abstract: A connector assembly includes a coupling body for securing an elongate member to an implant engaged to the spinal column. The elongate member is offset to one side of and transversely oriented to the implant. The coupling body includes a first passage for receiving the implant and a second passage for receiving the elongate member and a clamping member positioned about the elongate member. The coupling assembly also includes an engaging member that engages the coupling body and contacts the clamping member to clampingly engage the elongate member with the clamping member while manipulating the coupling body positioned about the implant to engage the coupling body to the implant.

Abstract: A spinal cross connector is configured for connection between spinal rods and provides allowance or space for spinal extensor muscles once the spinal process has been removed. The cross connector has curved first and second connection members that are adjustable in length and rotation relative to one another. A first clamping member is provided on the first connection member and defines first and second arcuate jaws that are adapted to clamp onto a first spinal rod. A second clamping member is provided on the second connection member and defines first and second arcuate jaws that are adapted to clamp onto a second spinal rod. Both the first and second clamping members are rotatable and thus provide the rotational adjustment. The cross-connector also provides easy in situ sizing and adjustability.

Abstract: A bone plate mounted on a bone. The bone plate has at least one opening for receiving a flush mounted cam. A through-bore passes from a side surface to opposing side surface of the bone plate. The through-bore has a diameter sized to allow insertion of a cable. A portion of the through-bore intersects with a peripheral portion of the opening. A second opening also passes from the side surface to opposing side surface. A cable may be inserted in the second opening, wrapped around the bone and its free end inserted in the through-bore. The cable may be tightened around the bone. The flush mounted cam can be rotated in place. Rotation of the cam results in the cam surface squeezing the cable between concave cam surface and walls of the opening, thereby locking the cable in the tightened state.

Abstract: A transverse spinal linking device links at least one spinal osteosynthesis bar to a transverse bar. The device may include a first part that has a vertical axis and a first jaw, a second part that has a second jaw, and a clamping resource. The first part may include a sliding surface, which may be inclined in relation to the vertical axis, and which may mate with at least one sliding surface of the second part. The sliding surfaces may be configured so that the descent of the second part results in an approach of the jaws, with the clamping action of the clamping resource causing the fixing and/or the locking of the device on the osteosynthesis bar and the fixing and/or the locking of the transverse bar.

Abstract: An enhanced pedicle rod clamp device for connecting two or more pedicle rods in spinal surgery is disclosed. The device may include an arm, an upper clamp, and a lower clamp, which are configured for coupling to a pedicle rod. The upper clamp may be coupled to the arm, and the lower clamp may be coupled to the upper clamp. The upper clamp may be rotationally and/or translationally movable with respect to at least one of the arm and the lower clamp. The lower clamp may be rotationally and/or translationally movable with respect to at least one of the arm and the upper clamp.

Abstract: A system for treating spinal deformities. A plurality of retaining clamps are fixed to a plurality of vertebrae and at least one elastic or super elastic rod is caused to pass through openings in the plurality of retaining clamps, the at least one elastic or super elastic rod being slidable within each of the plurality of retaining clamps along the axis of the spine to enable the spine to retain full flexion and extension in both its coronal and saggital planes.

Abstract: The present invention includes a system and method for the stabilization and fixation of the lumbar spine. Another aspect of the invention includes a system and method for the stabilization and fixation of the lumbar spine in a minimally invasive manner. The system can include a plurality of pedicle screws, a support rod, a plurality of rod clamps, and a plurality of coupling members. In one aspect, each coupling member can be configured to engage a proximal portion of a pedicle screw and can have a socket portion that is configured to receive a socket engaging portion of the rod clamp, such that the coupling member and the pedicle screw can be pivoted three-dimensionally relative to the rod clamp and the support rod.

Abstract: An orthosis for correcting spinal deformities by urging spinal vertebrae toward a vertical axis. The orthosis includes a series of retaining clamps fixed onto the spinous process of said vertebrae, each of said retaining clamps having guides for retaining at least one elastic rod.
