Patent ID: 8369930

Claim:
An MRI-compatible catheter, comprising: an elongated flexible shaft having a distal end portion, and an opposite proximal end portion; a handle attached to the proximal end portion, wherein the handle includes an electrical connector interface configured to be in electrical communication with an MRI scanner; an ablation tip at the shaft distal end portion, wherein an RF conductor extends longitudinally within the shaft to the electrical connector interface at the handle and that connects the ablation tip to an RF generator; and at least one RF tracking coil positioned adjacent the distal end portion, wherein the at least one tracking coil includes a conductive lead extending between the at least one RF tracking coil and the electrical connector interface and configured to electrically connect the at least one tracking coil to an MRI scanner, wherein the conductive lead has a length sufficient to define an odd harmonic/multiple of a quarter wavelength of the operational frequency of the MRI Scanner.
