Abstract
Cette invention concerne un cathéter à résonance magnétique utilisé pour la détection de position et l'imagerie comprenant un corps tubulaire de base (2) équipé d'une extrêmité distale, d'une extrêmité proximale et d'un circuit (10) pour la detection de position et l'imagerie placé à proximité de l'extrêmité distale. Ce circuit (10) est relié à l'extrêmité proximale par un conducteur (11) et il est conçu pour réagir au champs de résonance magnétique ou le détecter. Ce circuit (10) comprend au moins une bobine (13, 14) et un circuit de résonance (16, 17). Le circuit (10) est sensible à une gamme de fréquence présélectionnée du champs de résonance magnétique tel qu'un champs dont les fréquences avoisinent la fréquence de Lamor. La bobine (13, 14) et le circuit de résonance (16, 17) sont capables de detecter la position de l'extrêmité distale du cathéter et de reconstituer l'image du tissu environnant.
