Abstract: A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

Abstract: A method and apparatus are disclosed that provides a system to perform a procedure on a patient or on a patient's anatomy. The apparatus can include a guide member that includes at least three degrees of freedom of movement of a guide or alignment portion. The apparatus can be used to guide or form reference points for a guide to resect a portion of an anatomy.

Abstract: A method and apparatus for percutaneous and/or minimally invasive implantation of a construct. The construct may be implanted using a navigation system for planning and execution of a procedure. A plurality of portions of the construct may be interconnected using locations and paths determined and navigated with the navigation system.
