Patent number: 8549732Abstract: A surgical navigation system for navigating a region of a patient includes a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be repeatably placed on the patient in a precise location for guiding the instruments. The instruments may be precisely guided by positioning sensors near moveable portions of the instruments. Electrical sources may be electrically isolated from the patient.Type: GrantFiled: July 1, 2011Date of Patent: October 8, 2013Assignee: Medtronic Navigation, Inc.Inventors: Bruce M. Burg, John H. Dukesherer, Bradley A. Jascob, Paul Kessman

Patent number: 8320991Abstract: A portable system can be provided that works with a surgical navigation system. The portable system can control a localizer to assist in the tracking of a tracking device. The portable system can be provided to be substantially carried by a single user form one location to another. Further, various digital control components can be provided to assist in miniaturization, robustness, and the like.Type: GrantFiled: December 1, 2006Date of Patent: November 27, 2012Assignee: Medtronic Navigation Inc.Inventors: Bradley A. Jascob, Vince J. Doerr, Paul Kessman, Orey G. Block, Jeffrey Swetnam, John H. Dukesherer

Patent number: 8271069Abstract: A surgical navigation system for navigating a region of a patient that may include a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be placed on the patient in a precise location for guiding the instruments. The dynamic reference frames may be fixedly placed on the patient. Also the dynamic reference frames may be placed to allow generally natural movements of soft tissue relative to the dynamic reference frames. Also methods are provided to determine positions of the dynamic reference frames. Anatomical landmarks may be determined intra-operatively and without access to the anatomical structure.Type: GrantFiled: July 1, 2010Date of Patent: September 18, 2012Assignee: Medtronic Navigation, Inc.Inventors: Bradley A. Jascob, Scott Shaver, Todd Martens, Nadim Yared, Kirsten Boes, John H. Dukesherer, Mark W. Hunter
