Abstract
An apparatus having an insertable portion for holding a position sensor is disclosed. The position sensor can transmit a signal indicative of its position with respect to a field generator. The insertable portion of the catheter has fiducial markings that are detectable by an imaging modality when the insertable portion is inserted into the anatomical body. The fiducial markings are asymmetrical about at least a first axis of the insertable portion. After the insertable portion has been inserted into the anatomical body, the fiducial markings can be detected to facilitate registration of the position sensor held in the insertable portion to the anatomical body. The apparatus also has a fixing mechanism for releasably fixing the insertable portion to the anatomical body. The non-symmetrical fiducial markings facilitate unambiguous registration of the insertable portion to the anatomical body. When the insertable portion is inserted into the anatomical body to a location of interest, the fixing mechanism substantially rigidly fixes the insertable portion of the catheter to a part of the anatomical body near the location of interest.
