A catheter tracking system for tracking and monitoring a position of a catheter head within the human or animal body comprises a self referencing catheter. The self referencing catheter comprises an inner core, wherein the said outer sheath comprises a plurality of sensors and a fixing means for fixing the said outer sheath at a predetermined position, and wherein the said sensors receive signals generated by the said transducer, so as to produce measurement signals in accordance with a time of propagation of the said signals for determining the position of the said head relative to the said outer sheath.

Système de repérage d'un cathéter, comprenant un cathéter auto-référent, permettant de surveiller la position de la tête du cathéter à l'intérieur du corps d'un humain ou d'un animal. Le cathéter auto-référent est constitué d'un corps interne possédant un manchon extérieur muni de nombreux détecteurs et d'un dispositif de fixation dudit manchon dans une position prédéterminée. Les détecteurs reçoivent des signaux émis par le transducteur, afin de produire des signaux de mesure selon le temps d'émission de ces signaux dans le but de déterminer la position de la tête par rapport au manchon extérieur.
