Abstract
A coil electrode for use in an electrophysiology probe includes a first material having a relatively high radiopacity and a second material having a relatively high resiliency. This combination provides the necessary levels of durability, resiliency and radiopacity. An electrophysiological probe includes a support structure, at least one first electrode defining a first radiopacity supported on the support structure and at least one second electrode defining a second radiopacity supported on the support structure, the second radiopacity being greater than the first radiopacity. When viewed under a fluoroscope, the pattern of electrodes of varying radiopacities allows the physician to distinguish between individual electrodes.
