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 wood splitter apparatus comprising a base portion and a leg portion extending upwards from the base portion. An elevated cross member portion extending across the leg portion. A blade portion extending superiorly from the cross member portion. A leading upward edge at a superior aspect of the blade portion for splitting wood. A first splitter surface angled from a second splitter surface inferior to the leading upward edge. A collector portion positioned below the blade portion where the collector portion has a capture space. The collector having a floor face at a bottom of said capture space. The collector portion supported at an angle such that the floor face is sloped defining a high side and a low side where kindling split from a log over the blade portion falls into the high side of the collector portion and gathers on the low side of the collector portion.

Kindling splitter apparatus and methods of use

Systems and tools for inserting and securing an implant within the intervertebral space. An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. The implant may be provided with various securing members for fixing the implant within the intervertebral space. A tool may be used to insert the implant, which includes a plurality of shiftable implant engaging members that are shiftable between non-engaging and engaging configurations to alternatively release or hold the implant.

Intervertebral disc implant

An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein. In a further form, the device may be provided with a releasable connection so that the device may be connected in an insertion configuration and may be released in an operable configuration. Insertion tools and methods are also disclosed.

Artificial disc device

Systems and apparatuses for inserting an implant in intervertebral space

A method and apparatus for making a size measurement within an intervertebral space by placing an expandable and contractible device into the intervertebral space, expanding the device, measuring a size characteristic of the space, contracting the device and then removing it. The measurement may be accomplished by an external x-ray or other imaging device imaging the expanded device in situ or by mechanically operated devices. An expansion and contraction mechanism such as fluid containing bladder or mechanically shifted members expands the device which later contracts in a controlled manner to the contracted size. An apparatus and method is provided for the measuring of the intervertebral space at a controlled distraction force. The apparatus includes an expandable device for providing a measurement within the intervertebral space and facilitating the measurement of the angulations of the lordotic curve of the intervertebral space.

Intervertebral disc space sizing tools and methods

A system for replacing a natural nuclear disc in an intervertebral space has a spinal device configured for placement in the intervertebral space. An insertion tool is configured for holding the spinal device while the spinal device is inserted into the intervertebral space. A gripping member of the insertion tool has an end for adjustably holding the spinal device within the intervertebral space. A steering actuator of the insertion tool is operably connected to the spinal device and configured for pivoting the adjustably held spinal device within the intervertebral space while the steering actuator is controlled remotely from the intervertebral space.

System and methods for inserting a spinal disc device into an 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 one form, the implant retention device may include an elongated tensioning member having a portion configured to connect to the implant and at least one anchoring device disposed on the tensioning member, the anchoring device configured to at least partially penetrate spinal tissue such as the annulus, vertebral body, or other secure tissue.

Implant retention device and method

A spinal stabilization system includes a first engagement member and a support structure. The first engagement member is adapted to be disposed between a first vertebra and a second vertebra. The engagement member generally includes a seating surface for accommodating at least a portion of a laminar region of the first vertebra. The support structure engages a portion of the second vertebra. The structural cooperation of the first engagement member and the support structure is such that the engagement member restricts reduction of the intervertebral spacing between the first and second vertebrae.

Interlaminar stabilizing system

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

An implant device includes a pair of hook devices and an elongate guide device. The hook devices are configured to be disposed between and engage adjacent vertebral bodies. The elongate guide device is connected to the hook devices and allows for relative movement of at least one of the hook devices to adjust for the geometries of the vertebral surfaces to be engaged by the hook devices.
