  • Patent number: 10213169
    Abstract: Embodiments are described herein for determining anatomical landmarks on a patient by virtue of anatomical landmarks being called up from a database with an anatomical model and being converted into individual body dimensions and an individual position of the patient. As a result, anatomical landmarks may be called up from a database, calculated individually for the patient and used as an item of reference location information. The positioning of the patient table is thus considerably accelerated, wherein the accuracy is also improved. Thus, the item of reference location information may be calculated individually for the same patient in a different position or a different patient with different body dimensions by virtue of this item of reference location information being recalculated by the conversion rule for the respective patient.

    Abstract: An orthopedic implant system includes a set of provisional orthopedic implants having different implant sizes, in which each provisional implant facilitates an intraoperative selection of the next-smallest implant size without removing the provisional implant from the bone. All of the implant sizes share a common sagittal configuration of distal and anterior bone contacting surfaces, but have variable sagittal configurations only in the posterior bone contacting surfaces. Thus, where a relatively larger femoral provisional component is mounted to a femur, changing to a smaller provisional component (i.e., “downsizing”) can be accomplished by recutting only two of five original femoral cuts. Cut slots provided in each provisional implant are sized and positioned to correspond to the posterior bone contacting surface geometry of the next-smallest provisional implant size.

  • Patent number: 9931165
    Abstract: A light diffuser, which is particularly suitable for introducing diffuse light into a tissue, is produced by interpenetration of a diffuser material in a liquid state into a boundary layer of a porous shaping material, by which process a diffuser surface is formed having a surface structure which represents essentially a negative of the pore structure of the shaping material and includes undercut structures induced by a surface tension. The light diffuser is e.g. produced by introducing a diffuser blank including material that is liquefiable through mechanical vibration into the shaping material and simultaneously stimulating it with mechanical vibrations, such that the liquefiable material liquefies at least there where it is in contact with the shaping material and is pressed into the shaping material. An in situ production of the diffuser is particularly advantageous for photodynamic therapy in bone tissue.

    Abstract: A rod connector for joining a first rod and a second rod includes bore holes that are offset and/or non-parallel to each other. The rod connector provides an offset or non-parallel connection between the rods that allows for the rods to match the contour of a patient's body without requiring bending of the rods. The rod connector may include a first bore hole for receiving the first spinal rod and a second bore hole for receiving the second spinal rod that is adjustable relative to the first bore hole to adjust the position and/or orientation of the second spinal rod relative to the first spinal rod. The rod connector may comprise a first housing component defining the first bore hole and a second housing component that is movable relative to the first housing component and defining the second bore hole.

  • Patent number: 9907646
    Abstract: Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.

  • Patent number: 9839531
    Abstract: A process and system for performing orthopedic surgery to create a series of channels with a subject's bone to allow a reduced pressure system to be applied directly to the bone-implant interface to enhance bone healing is provided. The process for to promote healing of a bone of a subject includes creating a three-dimensional model of the bone; preoperatively planning a location of an implant relative to the model; creating a plan for the location of precision channels that reach the bone-implant interface based on the model and the implant; resurfacing the bone to fit the implant into or onto the bone based on the preoperative plan; and milling the precision channels into the bone in the location to promote healing of the bone and/or bone implant interface; and applying a pressure reduction system at the bone-implant interface to promote bone healing.

  • Patent number: 9782265
    Abstract: An implant is insertable in the joint space to separate bones of the joint. The implant has two endplates each configured to engage a separate articulating bone of the joint, and a threaded member positioned between the two endplates and configured to increase the space between the two endplates when the threaded member is rotated. A rotatable gear is engaged with the threaded member, and is engageable with a rotating gear of a connected implantation tool, so that rotation of the gear on the tool causes rotation of the threaded member and expansion of the implant to separate the bones. Connector portions on the tool and the implant may be rotated together to securely engage the implant and the tool so that the gears of the tool and the implant can be rotated using an actuator outside of the body, when the implant is inside the body.
