In addition, at least portions of the upper shaft are detachable from the lower shaft such that the upper shaft can be thoroughly cleaned and re-used if desired.

Allografts containing viable cells and methods thereof

Allograft biomaterials, implants made therefrom, methods of making the biomaterial and implants, methods of promoting cartilage, tissue, bone or wound healing in a mammal by administering the biomaterial or implant to the mammal, and kits that include such biomaterials, implants, or components thereof. For example, the allograft may include viable cells, for example, which were native to intervertebral discs and/or umbilical cords that the allograft was derived from.

Facet joint prosthesis

A facet joint prosthesis comprising an inferior prosthetic portion and a superior prosthetic portion is disclosed. Inferior prosthetic portion includes a first anchor member and a first articulating member and superior prosthetic portion includes a second anchor member and a second articulating member. The first articulating member comprises a support portion and first articulating surface and the second articulating member comprises a second articulating surface, and first and second articulating surfaces are configured and dimensioned to contact or engage one another. A flexible element is positioned between the support portion and the first articulating surface.

Polyaxial screw

The present invention generally is directed toward a spinal fixation system whereby a coupling element allows the physician to selectively lock or unlock either the connection between the coupling element and a fastener, such as to allow for repositioning of the coupling element, or the connection between the coupling element and an elongate rod. The locking or unlocking of these connections may be made independently and as desired by the physician.

Artificial intervertebral disc implant

An intervertebral disc for placement between adjacent vertebrae comprising: an anterior side; a posterior side; a first lateral side; a second lateral side; an upper endplate having an inner surface and an outer surface, wherein the outer surface of the upper endplate is adapted for contacting a first vertebra; a lower endplate having an inner surface and an outer surface, wherein the outer surface of the lower endplate is adapted for contacting a second vertebra; and an elastic membrane extending from the inner surface of the upper endplate to the inner surface of the lower endplate and defining an inner volume that is at least partially filled with a fluid, wherein the elastic membrane is affixed to the inner surface of the upper endplate and to the inner surface of the lower endplate.

Demineralized bone-derived implants

Selectively demineralized bone-derived implants are provided. In one embodiment, a bone sheet for implantation includes a demineralized field surrounding mineralized regions. In another embodiment, a bone defect filler includes a demineralized cancellous bone section in a first geometry. The first geometry is compressible and dryable to a second geometry smaller than the first geometry, and the second geometry is expandable and rehydratable to a third geometry larger than the second geometry.

Protocol for remote visual composition

A method and protocol to create and control compositions on a remote device is disclosed. The protocol allows servers and other devices to take advantage o f processing capabilities of remote devices to render compositions on the remote devices, thereby increasing server scalability and leveraging the remote device processing capabilities. The protocol provides high-level command packets to communicate resource command packets and control packets to the remote device with the payload having the information needed to process the commands.
