Abstract: A method and system to assist in a selection and planning of procedure and assist in selecting a prosthetic for the procedure. Generally, the system allows for image acquisition of a selected area of the anatomy. A model may be formed of the anatomy from the acquired images. The system may also allow for navigational tracking of the procedure to ensure that the procedure is substantially carried out relative to the selected plan.

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.

Abstract: A surgical navigation system for tracking a procedure relative to a patient is disclosed. The system can track a portion of the patient, an instrument, both, and both or either relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a minimally or non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits.

Abstract: An image guided navigation system for navigating a region of a patient includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of a patient. The tracking device tracks the location of the instrument in a region of the patient. The controller superimposes an icon representative of the instrument onto the images generated from the imaging device based upon the location of the instrument. The display displays the image with the superimposed instrument. The images and a registration process may be synchronized to a physiological event. The controller may also provide and automatically identify an optimized site to navigate the instrument to.

Abstract: A method for use during a procedure on a body. The method generates a display representing relative positions of two structures during the procedure.

Abstract: A method and apparatus for performing a calibration and navigation of a member. The member may be calibrated relative to a selected portion, such as a sensor on an instrument. The calibrated member may then be navigated with a selected system. The calibration technique can be infinitely flexible and not rigid or designed for specific components. Moreover, the calibration may occur when the member is interconnected to an end of the instrument that is non-co-axial with another end of the instrument.

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: An apparatus for determining the position of a wireless catheter probe being used during a surgical procedure. Magnetic fields are projected into an anatomical body to induce voltage signals in a sensing coil that are sufficient to describe the position of a wireless sensor/transmitter. The voltage signals are wirelessly re-transmitted by the sensor/transmitter as positional signals indicative of a current location of the sensor/transmitter in the anatomical body. In a preferred embodiment, the wireless catheter probe is self-powered using the induced voltage signals on a sensing coil. In another embodiment, induced voltage signals of a separate coil are used to power the device.

Abstract: An integrated surgical anchor/localization sensor is disclosed. The anchor is adapted to be secured to an anatomical structure and contains a sensor housing. A receiver is located within the sensor housing and is adapted to sense reference signals generated by a surgical guidance system. A transmitter, connected to the receiver, conveys to a processor signals received by the receiver, so that the signals transmitted by the receiver are indicative of a current position of the anchor. Various other structures and methods are also disclosed.

Abstract: A patient positioning device used to position a patient during a navigated medical procedure includes a contoured patient support and a portion of a navigation system. The contoured patient support positions the patient in a desired manner. The portion of the navigation system is integrated within the patient support, such that the navigated medical procedure may be performed in a substantially unobstructed manner.
