The present invention provides multi-functional medical catheters, systems and methods for their use. In one particular embodiment, a medical catheter (100) includes a flexible elongate body (105) having a proximal end (110) and a distal end (120). A plurality of spaced apart electrodes (130-136) are operably attached to the flexible body near the distal end. At least some of the electrodes are adapted for mapping a tissue and, in some embodiments, at least one of the electrodes is adapted for ablating a desired portion of the tissue. The catheter includes a plurality of tissue orientation detectors (140- 146) disposed between at least some of the electrodes. In this manner, the medical catheter is capable of tissue mapping, tissue imaging, tissue orientation, and/or tissue treatment functions.

L'invention concerne des cathéter médicaux à fonctions multiples, des systèmes et leurs procédés d'utilisation. Dans un mode de réalisation particulier, un cathéter médical (100) comprend un corps allongé souple (105) possédant une extrémité proximale (110) et une extrémité distale (120). Plusieurs électrodes espacées (130-136) sont fixées opératoires au corps souple, à proximité de l'extrémité distale. Au moins certaines électrodes sont conçues pour mapper un tissu, et dans certains modes de réalisation, au moins une des électrodes est conçue pour assurer l'ablation d'une partie choisie du tissu. Ce cathéter comprend plusieurs détecteurs d'orientation de tissu (140-146) placés entre au moins certaines électrodes. Ainsi, le cathéter médical est capable d'assurer des fonctions de mappage, d'imagerie, d'orientation et/ou de traitement du tissu.
