An implant device is provided that is configured for implantation at multiple locations between adjacent vertebrae. The implant device comprises an implant body, a first portion of the implant body, and a second portion of the implant body adjustably interconnected with the first portion. The implant body has a compact orientation and an extended orientation to allow the implant body to be shifted from one orientation to the other orientation for being positioned in any one of areas between the spinous processes of the adjacent vertebrae, between laminar regions of the adjacent vertebrae, spanning an opening in the annulus between the adjacent vertebrae, and in the intervertebral space between the adjacent vertebrae.

Intervertebral implant devices and methods for insertion thereof

A device for connecting two spinal rods is provided. In one form, the device includes two clamping devices for receiving and locking to spinal rods and a central bridge or plate member that couples the clamping devices. In one aspect, the clamping devices are unitary members with deflectable jaw portions that snap-fit and then locked by operation of actuators. In another aspect, one or both of the clamping devices are adjustably coupled to the central bridge or plate member to allow at least translation and pivoting or rotation of the clamping devices relative to a central axis of the elongate bridge member. The clamping devices may be coupled to the bridge or plate member with the same locking actuator that causes clamping of the clamp device so that the positions of the clamp device and the spinal rod are locked into place by manipulation of only a single locking actuator.

Posterior spinal stabilization plate device

An implant device is provided for implantation within an intervertebral space between adjacent vertebrae comprising an implant body, a rotatable portion and a piercing portion configured to pierce the adjacent vertebra.

Device for securing an implant to tissue

Spinal rods are provided that transition from one diameter to another without an extended transition region to which coupling devices may not be attached, allowing coupling devices for mounting the spinal rod to the spine to be secured almost anywhere along the rod's length without having a weakened transition point.

Size transition spinal rod

A prosthetic spinal implant having a securing member for fixing the implant relative to an adjacent bone. In one form, the securing member is deployable into a portion of the vertebral space for affixing the implant between the vertebrae. The securing member may be disposed substantially within the body of a bearing member of the implant when the securing member is in an undeployed orientation. In other forms, the securing member is provided separately from the implant such that it may be inserted into the intervertebral space after the implant has been placed in an implanted orientation between the vertebrae. In such forms, the securing member is configured for ease of insertion between an outer bearing surface of the implant and an adjacent bone via linear or rotary motion.

Systems and methods for sizing, inserting and securing an implant in intervertebral space

An implant retention device is provided to assist in restraining movement of a nuclear implant and to assist in preventing expulsion of the nuclear implant through an incision portal or defect in the annular wall. In general, the implant retention device blocks or obstructs at least a portion of an opening in the annular wall, thereby keeping the implant from exiting the nuclear space through the annular opening. In one form, the implant retention device comprises an expulsion prevention member positioned adjacent the nuclear implant and configured to transition between a compressed position and an expanded position. In another form, the implant retention device may comprise a mounting portion to be positioned adjacent one of the vertebral bodies, a blocking portion for at least partially obstructing the annular opening, and an end projection at a terminal end of the blocking portion to resist expulsion of the implant through the annular opening. In yet another form, the implant retention device may include an elongate blocking member having annulus connector portions extending from each side of the blocking member for engaging with an annular wall.
