摘要： A wound closure device has internal and external components designed to close, shrink or approximate an open wound. The internal component preferably comprises sachets filled with highly absorbent material such as carboxymethylcellulose, disposed at the surface of the wound bed to absorb exudate from the wound. The external components preferable include paddles that adhere to the skin, and form part of, or have a mechanism to couple to an elastic tensioning fabric. The internal component is placed between the open wound and the elastic tensioning fabric, such that expansion of the internal component applies pressure on the wound base. It is contemplated that the two components will work synergistically together to create ‘micro-deformation’ forces that stimulate granulation tissue.

摘要： An intervertebral disc placement system includes a multi part intervertebral disc, such as a mobile core disc, and an associated placement instrument. The placement instrument holds the disc securely with the disc endplates angled for ease of placement of the disc into an intervertebral disc space and quickly releases the implant within the disc space. The disc includes upper and lower plates having notches in inner surfaces for engagement of the placement instrument. The placement instrument has a rotatable key configured to fit into the first and second notches to grasp the disc from the interior and eliminate the need for an external grasping mechanism which could interfere with disc placement.

摘要： An intervertebral disc is provided having an upper plate, a lower plate, and a core. The upper and lower plates include outer vertebral body contacting surfaces which are provided with attachment enhancing features to ensure bone integration. The attachment enhancing features shown include one or more fins, serrations and teeth. An opposite surface of the plates from the vertebral body contacting surfaces is formed with a recess which serves as a bearing surface for the core. In order to form an intervertebral disc with a lower disc height, at least one of the recesses is provided opposite a corresponding dome shaped portion on the vertebral body contacting surfaces. This allows the plates to be formed with a thinner profile for a smaller overall disc height. In addition to providing a lower overall height to the artificial disc, the dome shaped portion of the plates also provides a more anatomically shaped outer vertebral body contacting surface.

摘要： A prosthetic disc for insertion between adjacent vertebrae includes a core having upper and lower curved surfaces, upper and lower plates, and peripheral restraining structure on at least one of the upper plate, the lower plate and the core. Each plate has an outer surface which engages a vertebra and an inner curved surface which slides over the curved surface of the core. The peripheral restraining structure serves to hold the core against a curved surface of at least one of the plates during sliding movement of the plates over the core.

摘要： A prosthetic disc for insertion between adjacent vertebrae includes upper and lower plates, a core disposed between the plates, and at least one projection extending from at least one of the upper and lower curved surfaces of the core into at least one recess of one of the inner surfaces of the plates. The recess is oversize with respect to the projection to allow sliding movement of the plate over the core while retaining the core between the plates during such sliding movement. The projection(s) may include a rod extending through an axial hole in the core, multiple surface features of the core, or the like.

摘要： The invention concerns an intervertebral prosthesis placement instrument which can be used to facilitate accurate positioning of a spinal disc prosthesis between adjacent spinal vertebrae. The instrument (10) has opposed jaws 12 formed with tips (24) that are shaped for insertion between the vertebrae. The jaws can be moved apart from one another to distract the vertebrae, allowing the prosthesis to enter between the vertebrae. The jaws also have opposed surfaces which are shaped to embrace the prosthesis between them and to guide the prosthesis into position.

摘要： The invention concerns a digital joint arthroplasty (10). The arthroplasty has a stemless, unitary body having opposite sides (12, 14) at least one of which is formed with a curved concavity shaped to receive, in articulated manner, a bone end in an MCP, PIP or DIP joint. In some embodiments, both of the opposite side surfaces are concavely curved while in other embodiments, only one side surface (12) is so curved, the opposite surface (40) being flat. In use the arthroplasty is installed between the shaped ends of bones which meet at the MCP, PIP or DIP joint. The absence of stems means that the installation of the arthroplasty is less surgically invasive than is the case with conventional arthroplasties having inter-medullary stems.
