A dynamic intervertebral spacer includes a ring which is split on an anterior portion. A posterior portion of the ring acts as a torsion spring. After implantation, the ring is able to act as a spring between superior and inferior vertebral bodies, thus allowing dynamic bone growth in fusion procedures.

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

In various exemplary embodiments, the present disclosure provides a process for the conversion of certain polymers into diamond and diamond-like materials using laser pulse annealing. The process includes transforming the polymer to carbon, melting the carbon and quenching the carbon melt into to form Q-carbon, diamond, and/or graphene. The process can be applied to a polymer film such aa a polytetrafluoroethylene (PTFE) tape. An object can be coated with the polymer film which can then be converted to Q-carbon, diamond, and/or graphene using laser pulse annealing. A process is also provided for making a three-dimensional object using a combination of, for example, 3D printing the polymer and converting each layer of polymer into Q-carbon, diamond and/or graphene.

An expandable interbody fusion device and an associated instrument for inserting the device into an intervertebral disc space, expanding the device and for use in delivering graft material into the device once expanded in the disc space. The device is small enough to fit through Kambin's triangle yet is capable of expanding both in the vertical direction to accommodate spinal lordosis and in the lateral direction to provide sufficient structural support for opposing vertebral bodies laterally within the disc space. A process of forming textured top and bottom surfaces of the device by initially laser ablating each surface with a nano-second pulsed laser followed by laser ablating those surfaces with a femto-second pulsed laser.

A scaffold (12) for tissue engineering comprises an inner portion (14), an outer portion (16), and a base portion (22) connecting the inner portion and the outer portion. The inner portion (14) comprises a channel (18) surrounded by a first set of one or more walls. The outer portion (16) comprises a second set of one or more walls. The portions are arranged such that the second set of one or more walls substantially surrounds the first set of one or more walls with a spacing between the first and second sets of walls defining a cavity (20) between the inner portion (14) and the outer portion (16). The inner portion (14) and the outer portion (16) may have different shapes; and/or the scaffold (12) may further comprise a filler material in the cavity (20) defined between the inner and outer portions.

The present disclosure relates to a method of manufacture of a dental implant for a molar, including acquiring, structural data corresponding to bones of the facial skeleton, the bones of the facial skeleton being proximate the molar, selecting, as a dental implant fixation surface, a surface of the bones based upon a determined thickness of the bones, generating, based on the selected dental implant fixation surface, a contoured surface of the dental implant, and fabricating, based upon an instruction transmitted by processing circuitry, a bone plate extending from a buccal end of a cylindrical plate of the dental implant, the cylindrical plate having support lattices extending therefrom, at least one support lattice of the support lattices being arranged on a lingual end of the cylindrical plate, the cylindrical plate having an opening in a central region thereof, the opening being configured to receive a dental post.

A method of replacing a portion of a cranium with a hard tissue implant can include resecting a first portion of the cranium to define a first margin region. The first portion of the cranium can be analyzed to determine if the first margin region is free of cancerous cells. A second portion of the cranium can be resected to define a second margin region that is larger than the first margin region when the first margin region is not free of cancerous cells. An outer implant can be secured to the cranium at the second margin region. An inner implant can be secured to the outer implant.

The invention relates to an implant (1) for introducing into a patient, having an implant body that is at least partially resorbable and is porous at least in some regions and that is made of a ceramic carrier material (2), the carrier material being provided with a donor material (3) that delivers ions to influence the patient's cellular metabolism in the implanted state, the carrier material (2) being interspersed with the donor material (3). The invention also relates to a method for producing an implant (1) of said type.

Medical devices, such as implants, and corresponding methods of manufacturing using an additive manufacturing technique, wherein the finished medical devices include a build plate retained therein, are disclosed. In some embodiments, the medical device includes a build plate having a plurality of peaks and a plurality of indentations, the plurality of peaks and the plurality of indentations together defining a surface roughness of an exterior surface of the build plate. The medical device may further include a first layer formed atop the exterior surface of the build plate, the first layer comprising a plurality of powder structures disposed over the plurality of peaks and the plurality of indentations. In some embodiments, an average peak distance between adjacent peaks of the plurality of peaks is less than an average width dimension of at least a portion of the plurality of powder structures.
