    摘要： Orthopedic plates (including anterior cervical plates), plate systems, and methods of use allow orthopedic screws to be placed with full visualization. This allows screw placement without use of specialized locating instruments or pins. The new plates are introduced to the surgical wound after the screws are placed and are secured by a press or interference fit. Because the screws are placed before the plates are introduced, the screws function as attachment points for distraction implements. The new plates and plate systems obviate the need to achieve a particular position and angulation of screws. The screws allow more angulation, and plate eyes adjust to screw position. Plate eyes translate to match the effective plate size to the screw placement, thereby allowing each plate to fit multiple screw spacings. Plates are adapted to adjust to bone remodeling or subsidence. Screw eyes can slide to maintain graft contact and compression.

    摘要： A self-retaining screwdriver includes an elongate inner driver rod and an outer sleeve disposed about the inner driver rod and having a distal end, the distal end having a plurality of fingers. Each of the fingers includes a retention feature. The retention feature may be formed as an area of thickening of the finger, whereby an effective diameter of the outer sleeve at the retention features of the fingers is increased. When the inner driver rod is disposed within the outer sleeve with a distal portion of the inner driver rod extended as far as the retention feature, the presence of the inner driver rod prevents the fingers from being radially displaced inwardly. When the inner driver rod is at least partially withdrawn, the distal portion of the inner driver rod does not extend to a distal end of the fingers, and the fingers can be radially displaced inwardly.

    摘要： Medical implants and implant components are formed by additive manufacturing processes. The additive manufacturing process used results in the implants or implant components having surfaces having a higher coefficient of friction as opposed to a similar implant manufactured using a different process, such as having a machined surface. The higher coefficient of friction of the relevant surface is particularly useful for multi-component implants that are to have a fixed relationship between the components based at least in part on a frictional engagement between them. While manufacturing via an additive manufacturing process may result in an implant component having slightly less strength for its size when compared with traditional manufacturing methods, the advantage of the increased coefficient of friction may offset any loss of component strength, and may allow for overall reduced implant size while maintaining other desirable implant characteristics.

    摘要： An expandable interbody spacer for use in spinal fusion procedures includes a plurality of rigid segments connected by flexible connections to form a ring encompassing and defining a hollow central area of variable dimensions. The flexible connections between the plurality of rigid segments may include flexible regions formed between the rigid segments or a continuous flexible member extending along a multisegmented region. The flexible regions formed between the rigid segments may be integrally formed with the rigid segments. One or more of the flexible regions formed between the rigid segments may include a plurality of flexure divisions extending between adjacent rigid segments. One or more of the flexible regions formed between the rigid segments may include a flexure extending between adjacent rigid segments. The rigid segments may include surfaces to limit the range of motion between adjoining rigid segments.

    摘要： A surgical implant includes a deployable, retractable, or removable ramped nose. During insertion of the implant, the ramped nose is deployed such that the ramped nose can serve to distract a space into which the implant is inserted. At some point during or after insertion, the ramped nose can be collapsed and removed or retracted so that it does not extend beyond the space into which the implant is inserted, while the implant extends at full height throughout the space into which the implant is inserted. The implant includes an implant body having a deployable ramped nose adapted to selectively extend from the body and transition from a first height proximate the implant body to a second, shorter, height distal from the implant body. The deployable ramped nose is adapted to distract an implant site upon insertion of the implantable medical device.

    摘要： A porous implant design method includes defining a design volume for a porous implant, a load to be borne by the design volume, and an objective function solution characteristic related to the design volume. Next, the load is divided into a plurality of sub-loads and an optimization procedure is performed: until all sub-loads have been applied, one of the plurality of sub-loads is applied to the material in the design volume, material from the design volume is removed such that remaining material within the design volume is capable of bearing one of the plurality of sub-loads while satisfying the objection function solution characteristic; the remaining material defines a void space without material, the void space is set as a new design volume for any remaining sub-loads, the new design volume is set as being full of material. Then, the remaining material from each cycle of the optimization is combined.
