| 20080234691 | Flex-Rod, Curvature-Adaptable - The design of a rod is disclosed that can serve in general structural applications or as an orthopedic spinal implant to retain formation or stimulate the reduction of deformity as occurring in scoliosis and kyphosis. Different from common solid rod implants, the here-disclosed rod is curvature-adaptable in three dimensions to the actual or desired curvature or shape of the spine and can be provided with elasticity in order to serve as support or agent for curvature correction. The curvature adaptation of the proposed rod can be done with minimal force before or after implantation by means of the simple rotation of always only one in a pair of wedge shaped washers inserted between rod segments while leaving full mechanical strength or elasticity to the rod after curvature adaptation. The rotation of the washers can be done by various means, either once before implant or subsequently in the implanted state. | 09-25-2008 |

| 20120004664 | MEDICAL IMPLANT EXTRACTION DEVICE - Extraction instruments and systems for use in revision arthroplasty are provided. The extraction instruments are shaped and configured to fit within the typically tight confines in which revision arthroplasty is performed, and to enhance the surgeon's control over the axis, quantum and speed of the force that is required be applied to disrupt a bone-to-prosthesis bond. This enables completion of a revision arthroplasty to proceed more quickly, and with reduced risk that unwanted movements might cause accidental injury to nearby vital structures. | 01-05-2012 |
| 20120089149 | Medical device insertion instrument - A known x-stop implantation instrument is modified to provide a slide hammer mechanism to selectively apply an impact force. Both the axial location of the slide hammer and the angle of the slide hammer may be adjusted. A surgeon, when necessary or desirable, may thus apply an impact force to the forward end of the implement having a least a component of force in the direction of insertion of the x-stop device. The invention permits the surgeon to vary both the position along the shaft where the impact is applied as well as the angle at which the impact is applied relative to the direction of insertion. | 04-12-2012 |
| 20120150190 | Systems and Methods for Implant Removal - Implant removal systems and methods for using the system for removing an implant from a bone are disclosed herein. In an embodiment, a method for removing an intramedullary implant from a bone includes navigating a guidewire into an intramedullary cavity of the bone; inserting the guidewire into a lumen of an intramedullary implant located in the intramedullary cavity of the bone; advancing a removal screw over the guidewire to the intramedullary implant; threading the removal screw into the lumen of the intramedullary implant to engage the removal screw to the intramedullary implant; and applying impaction force on the removal screw to remove the intramedullary implant from the intramedullary cavity. | 06-14-2012 |
