Abstract:
An MRI-compatible intrabody device includes an elongated flexible shaft having a distal end portion, an opposite proximal end portion, an electrical connector interface configured to be in electrical communication with an MRI scanner, and a tracking coil assembly adjacent the shaft distal end portion. The tracking coil assembly includes a first spool having opposing first and second end walls and a second spool having opposing third and fourth end walls. The second spool is in end-to-end relationship with the first spool such that the second and third end walls are in adjacent, spaced-apart relationship. A tracking coil is wound around the first spool, and a coaxial cable is wound around the second spool. An outer conductor of the coaxial cable is connected to one end of the tracking coil and the inner conductor of the coaxial cable is connected to an opposite end of the tracking coil.
