Abstract: A shoulder implant system includes a humeral stem implant, a humeral neck implant component, a humeral head implant component, and a glenoid implant. The humeral stem implant has a fin coupled to an exterior surface thereof that is inwardly tapered at an angle relative to vertical. At least a portion of the fin forms a wedge that directly engages and compacts cancellous bone during installation of the humeral stem implant. The humeral neck implant component is configured to be coupled with the humeral stem implant. The humeral head implant component is configured to be coupled to the humeral stem implant via the humeral neck implant component. The glenoid implant has a plurality of peripheral pegs. Each of the peripheral pegs has a plurality of sets of resilient lobes.

Abstract: A driver instrument for engaging and transferring rotational torque to a bone screw assembly which includes a shaft and sleeve adapted to engage and couple the bone screw assembly into a single coaxial unit while the bone screw assembly is being driven into a bone and then to release the bone screw assembly from the driver instrument. The driver instrument includes an elongate shaft, a sleeve, and bone screw assembly engaging features on the elongate shaft and/or the sleeve.

Abstract: Embodiments of the invention include expandable, implantable devices and methods. Devices expand linearly to provide secure fixation between or among anatomical structures. In some embodiments, an implant replaces one or more vertebral bodies of the spine.

Abstract: An expandable medical implant for supporting skeletal structures. The medical implant having a length along its expandable dimension. The implant having a first tubular member with a connection end, an opposite skeletal interface end, and a central expansion instrument opening. Also, the implant has a second tubular member with a connection end configured to engage with the connection end of the first tubular member. The second tubular member having an opposite skeletal interface end. Additionally, an expansion instrument is insertable through the central expansion instrument opening and expandable against the first tubular member and the connection end of the second tubular member to expand the medical implant. The combined first and second tubular members are of a greater dimension along the length of the implant than the combined first and second tubular members are in any dimension perpendicular to their length.

Abstract: Intervertebral spacers are provided for use in orthopedic treatment of spinals defects. The intervertebral spacer is formed of a shape memory polymer. The spacer can be fabricated into a desired configuration and then deformed into an alternative or deformed configuration. Cooling the deformed spacer effectively freezes the spacer into its deformed conformation. The deformed configuration can be selected to facilitate implantation of the spacer into a prepared disc space between adjacent vertebrae. During operation, the surgeon can heat the spacer to allow it to revert to its original configuration. The spacer in its original conformation is sized to restore and/or maintain the adjacent vertebrae in a desired conformation and disc space height.

Abstract: This invention relates to an deformable stent or catheter formed of a shape-memory polymeric material (SMP). The stent is originally molded into a desired configuration for treatment of a variety of medical treatments. Subsequently, the stent can be deformed to a second configuration selected to facilitate implantation. Either during implantation or after implantation, the stent can be stimulated to induce it to deform, for example, but not restricted to reverting to the original molded configuration or an approximation of that configuration.
