Patent Images
1. A device for image guided surgery that includes a k-wire for insertion in an anatomical body, the k-wire comprising:
- at least one electromagnetic position-indicating element, located in a distal end of the elongated member and capable of providing the position and orientation of the location of the position-indicating element;
at least one conductive lead-wire from which signals are carried from the at least one electromagnetic position-indicating element at the distal end along at least a portion of a length of the k-wire to a proximal end;
a plurality of connection bands associated with the k-wire, wherein the plurality of connection bands are located at the proximal end and connect the at least one conductive lead-wire to an electromagnetic position sensor system.
