Abstract: An instrument guide system for use with a surgical navigation system, the instrument guide system comprising a handle assembly, an instrument attachment assembly, a shaft connecting the handle assembly to the instrument attachment assembly, an electromagnetic sensor assembly removably mounted within an opening in the handle assembly, and an instrument removably attachable within a bore of the instrument attachment assembly.

Abstract: A percutaneous registration apparatus and method for use in minimally invasive spinal surgery. The apparatus including a holding member, first and second clamping members, first and second gripping members, and an adjustment mechanism for closing and opening the first and second gripping members.

Abstract: Described herein is one or more implementations for a percutaneous spinal registration-and-access tool for minimally invasive spinal surgery involving lumbar pedicle screw fixation and registration (which is the set-up process for spinal computer navigation). This spinal registration-and-access tool aids registration by allowing more precise targeting of the spinous process (of the vertebrae) and safe working channel for percutaneous placement of a sharp tool (e.g., a bone pin) through the protected subcutaneous tissue.

Abstract: A tissue tracking assembly and method is disclosed herewith. The tissue tracking assembly comprises: a flexible probe with a proximal end and distal end, the proximal end incorporates an electric connector and the distal end incorporates at least one trackable sensor. A delivery system is provided in association with the flexible probe to accurately embed the flexible probe within a tissue. The delivery system is configured to be attached to the flexible probe during insertion of probe within the tissue and detaches from the flexible probe after embedding the probe within the tissue.

Abstract: A system and method for placement of at least one implant comprising an imaging system configured for taking at least one image of a patient; a navigation system configured for tracking position and orientation of at least one implant; a computer configured to measure and calculate the position and orientation of the at least one implant; and a display configured to display the at least one image of the patient and superimpose a graphical representation of the at least one implant with position and orientation information of the at least one implant on the at least one image of the patient.

Abstract: An image guided surgical system and method for targeting the precise patient specific anatomical placement of surgical instruments and motion preservation implants with surgical navigation. The system and method comprising a surgical navigation system; at least one imaging system coupled to the surgical navigation system; at least one computer coupled to the surgical navigation system and the imaging system having planning software for measuring clinical parameters of anatomy of a subject to be operated on; and at least one display for displaying imaging data, planning data and tracking data.

Abstract: Certain embodiments provide systems and methods for intraoperative implant measurement. Certain embodiments of a method include noting a location of a first implant, noting a location of a second implant, measuring a distance between the first and second implants based on the location of the first implant and the location of the second implant, and displaying the distance to a user. Certain embodiments of a system include a processor configured to determine a distance between a first implant and a second implant based on tracking information for a location of the first implant and a location of the second implant and a display configured to display an image including the first and second implants and the distance to a user.
