A ratcheted spinal device including a variable-length member including a ratchet mechanism that has an operative configuration that allows a change in length of the variable-length member in one direction and prevents a change in length of the variable-length member in an opposite direction, wherein the variable-length member includes polyaxial-joint attachment members for attachment to bone, which permit pivoting movement of the attachment members about more than one pivoting axis.

Ratcheted spinal device

A spinal device includes a rod which has a first end disposed in a housing and a second end which protrudes out of the housing through an aperture and which is movable to protrude more out of the housing or less out of the housing. A biasing device, mounted on the rod, includes a series of connected at-least partial coils. A first end of the biasing device is arranged to abut against the housing and a second end of the biasing device, opposite to the first end, is affixed to the rod.

Biasing device for spinal device

A spinal pedicle screw system includes distractions rods and has the ability to be distracted after the screws are inserted into the pedicle and maintain polyaxial motion via polyaxial joints.

Expandable polyaxial spinal system

A spinal device including a variable-length member including a ratchet mechanism that has an operative configuration that allows a change in length of the variable-length member in one direction and prevents a change in length of the variable-length member in an opposite direction, wherein the variable-length member includes polyaxial-joint attachment members for attachment to bone, which permit pivoting movement of the attachment members about more than one pivoting axis, characterized by a force applicator operative to adjust or advance the ratchet mechanism.

Ratcheted spinal devices

A spinal screw includes a shaft formed with a lumen and including a head, and a distal movable member including a distal tip and arranged to move in a distal portion of the lumen. A distal movable member () includes a proximal surface () arranged to abut against a stopper () formed in the shaft ().

Spinal screw with movable tip

A facet distraction prosthesis () includes an array of facet distraction base elements () connected to each other by one or more connector elements (). A pair of diagonally adjacent base elements () are connected to each other by a set of or more connector elements () which intersects with another set of one or more connector elements () that connects another pair of diagonally adjacent base elements (). The connector elements () are flexible so that the base elements () can flex with respect to each other and adapt to a geometry of a facet joint.

Facet distraction and fusion prosthesis

A spinal implant includes first and second pedicle screws, each of which comprises a threaded shank coupled to a head. First and second cantilevered arms are coupled to the first and second pedicle screws, respectively. The first cantilevered arm includes a contact member arranged to contact and move over a contact portion of the second cantilevered arm.

Bi-directional motion spinal implant

A delivery device includes a guide tool and an impact tool. The guide tool includes an elongate body formed with a longitudinal guide channel, whose inner perimeter is made to complement an outer contour of an implant. The elongate body is formed with a longitudinal impact-tool channel, whose inner perimeter is made to complement an outer contour of the impact tool.

Implant delivery system

A facet distraction prosthesis includes an array of facet distraction base elements, connected to each other by a set of connector elements located at adjacent base elements. The set of connector elements includes a male connector having an at least partial cylindrical or spherical contour that is received in, and articulates with, an at least partial cylindrical or spherical recess of a female connector, so that adjacent ones of the base elements can bend in multiple degrees of freedom about different bending axes with respect to each other and adapt to a geometry of a facet joint.

A spinal cage includes a first support plate pivotally connected to a second support plate by a hinge, and a plate mover actuated by an actuator and located between the first and second support plates. The plate mover is arranged to slide against an inclined surface on the first support plate. A hinge is journaled in an elongate aperture formed in a hinge housing protruding from first support plate, the hinge being free to translate and rotate in the elongate aperture.

Adjustable spinal cage

A spinal cage () including first and second spinal attachment members () attachable to vertebrae (), the first and second spinal attachment members () articulating with one another by means of an articulation joint (), characterized by a wedge element () arranged for wedging between the first and second spinal attachment members (), and an actuator () linked to the wedge element () for moving the wedge element () in a direction that wedges the wedge element () further in between the first and second spinal attachment members () or further away from the first and second spinal attachment members ().
