An implant device having a non-conductive base structure with at least two exposed or exterior surfaces wherein at least one of the exposed or exterior surfaces has attained electrical conductivity on at least portions of the surface by an energy exposure wherein portions of the exposed or exterior surfaces are transformed by the energy exposure to attain the electrical conductivity.

A hand manipulated endoscopic medical device includes a body having a proximal end, which is hand manipulated, a distal end which includes a manipulator, a light emitting device at the distal end, an imaging device at the distal end. A tool for extracting an artificial lumbar disc from between a pair of vertebral plates includes a handle, a member for transmitting force, and a sharpened end, specially configured to be placed between the artificial disc and the vertebral plate. A tool for implanting or explanting a ball to or from an artificial lumbar disc includes a pinion shaft and a pinion shaft enclosure, with a tightening knob at the proximal end of the shaft enclosure and coupled to the pinion shaft, a pinion at the distal end of the pinion shaft, a grappling device at the pinion, and a pair of semi-circular rings.

Disclosed herein is an intervertebral disc prosthesis comprising a first cantilever arm; the first cantilever arm comprising a shaft that is affixed to a disc; a second cantilever arm that comprises a plurality of rods that contact the disc; the plurality of rods being equidistant from a central axis of the shaft; and a third cantilever arm that comprises a platform to which are attached a plurality of rings; the rings being concentrically disposed about the shaft; the rings being in operative communication with each other; where the plurality of rods contacts the platform; and where the second cantilever arm has more degrees of freedom than the first cantilever arm, while the third cantilever arm has a number of degrees of freedom that are greater than or equal to the number of degrees of the second cantilever arm.

A device for insertion into a spinal (intervertebral or intravertebral) space is expandable and contractable. The device includes a body assembly, a top member configured to fit within a gap in the body assembly, a drive gear disposed within the body assembly at a distal end of the body assembly, a proximal gear assembly, and a distal gear assembly. The drive gear includes a receiver accessible from outside the body assembly and configured to be rotated in order to rotate the drive gear. Each gear assembly is attached to the top member. The distal gear assembly engages the drive gear. Rotation of the drive gear in a first direction causes the gear assemblies to translate the top member away from the body assembly, and rotation of the drive gear in a second direction causes the gear assemblies to translate the top member towards the body assembly.

The present invention provides a supporting member for implanting into a vertebra of a subject, including: a hollow body including an upper surface and a lower surface opposite the upper surface; a first guiding part formed on the upper surface; a second guiding part corresponding to the first guiding part and formed on the lower surface; a first engaging part formed on the upper surface; and a second engaging part corresponding to the first engaging part and formed on the lower surface; wherein the second guiding part extends out an extending part from a side of the hollow body, and the extending part is configured to be slidably coupled to a first guiding part of another supporting member sliding to the lower surface of the supporting member, as a result two supporting members are slidably coupled to each other and engaged to each other. According to the invention, one single supporting member can be implanted into a vertebra of a subject, or two or more supporting members can be in sequence introduced into a vertebra of a subject and combined together therein.

A device promotes osseointegration between two adjacent vertebrae. The device includes a spacer fabric having a top layer, a bottom layer, and intermediate filler fibers connecting the top layer and the bottom layer. The spacer fabric is capable of expanding to fill a gap between two adjacent vertebrae.

A spine stabilization and fusion system includes a lateral cage having a lateral cage bore hole. The system also includes a lateral cage insertion shaft comprising a leading end, a mid-portion, and a terminal end. A shape of the leading end matches a shape of the lateral cage bore hole such that the leading end mates with the lateral cage bore hole via a friction fit. The system also includes a lateral plate having a lateral plate bore hole and a plurality of holes, where the lateral plate bore hole receives the mid-portion of the lateral cage insertion shaft, and where the plurality of holes receive fasteners to couple the lateral plate to one or more vertebra.

A monitoring system includes: (1) an implant having at least one sensor and configured for at least partial insertion into a patient, a first one of sensors being in contact with a perimeter of a hole in a body portion of the implant for accepting a fastener; (2) a microchip associated with the implant and the sensor, the microchip configured to receive at least a first signal from the sensor; (3) a transmitter associated with the microchip for transmitting a second signal, representative of the first signal; (4) a receiver located outside of the patient, the receiver configured receive the transmitted second signal; and (5) a display device associated with the receiver, the display device configured to provide an audible or visual representation of the second signal to a user.

Systems and methods for distracting an intervertebral disc space are provided. The systems use an expandable trial with telescopic stabilizers. The systems and methods of distracting an intervertebral space are provided in a manner that addresses the problem of subsidence. The method includes inserting the trial into the intervertebral space in a collapsed state and, once inserted, the trial is then used for distracting the intervertebral space using an expansion that includes a first stage and a second stage. The first stage includes expanding the trial laterally toward the peripheral zones of the top vertebral plate and the bottom vertebral plate, and the second stage includes expanding the trial vertically to distract the intervertebral space.

Disclosed herein are aspects of expandable interbody devices having an unobstructed graft material containment space. Such expandable interbody devices have a structure in which an overall plan view area of the graft material containment space is devoid of elements of the expandable interbody device enabling adjustment of the expandable interbody devices between a collapsed configuration and displaced configuration (e.g., an expanded configuration and/or a tilted configuration). In this manner, expandable interbody devices configured in accordance with embodiments of the disclosures made herein do not have obstructions within the graft material containment space thereof that limit the available volume of graft material and associated bony material growth that may be contained within the graft material containment space.
