description Catheter devices, systems and methods for penetrating from one location within a patient's body to another location. An elongate catheter is insertable into a natural or man-made lumen within the body of a patient. A penetrator is advanceable from the catheter to a target location outside of the lumen in which the catheter is positioned. An optical imaging or tissue characterization apparatus (e.g., an optical coherence tomography apparatus) is useable to image the anatomy and/or sense variables within tissue so as to locate the target location relative to indicia of the trajectory on which the penetrator will advance from the catheter. The operator may then adjust the position and/or rotational orientation of the catheter such that when the penetrator is subsequently advanced, the penetrator will enter the target location. L'invention porte sur des cathéters allongés (et les systèmes et procédés associés) permettant de passer d'un point à un autre du corps de patients après avoir été insérés dans un orifice naturel ou artificiel. On peut faire progresser un pénétrateur partant d'un cathéter vers un emplacement cible situé hors de l'orifice d'introduction. On utilise à cet effet un appareil optique d'imagerie ou de caractérisation de tissus (par exemple un tomographe à cohérence optique) pour voir l'anatomie et/ou détecter les aspects variables des tissus et localiser un emplacement cible en fonction d'indices situés sur la trajectoire du pénétrateur progressant depuis le cathéter. L'utilisateur peut modifier la position ou l'orientation en rotation du cathéter pour permettre au pénétrateur de poursuivre sa trajectoire et d'arriver à l'emplacement cible.
