摘要： 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.

摘要： A medical instrument assembly is disclosed. The medical instrument has proximal and distal ends. A receiver coil being mounted proximate to a distal end of the medical instrument, the receiver coil being electrically connectable at a proximal end of the medical instrument. A deployable object being disposed and movable within the medical instrument. The deployable object bearing a high magnetic permeability material located proximate to the receiver coil. The high magnetic permeability material and the receiver coil combining to form an inductive element having an inductance that varies in a predetermined manner with the position of the deployable device relative to the receiver coil. A determination of the inductance being performed at the proximal end of the delivery catheter indicates the extension of the deployable device through the medical instrument.
