An electrophysiology guidewire (20) including an elongated core (22) and a biocompatible coil mechanism (24) disposed helically around the core (22) to define a plurality of windings. The coil mechanism (24) is formed from at least one conductor (A, B, C, D) covered externally with a layer of insulation. The insulation is adapted for selective removal to expose a portion of the at least one conductor (A, B, C, D) to define at least one electrode (#1, #2, #3, #4). The guidewire (20) is manufactured by carrying out the steps of selecting an elongated moldable core (22); coiling at least one insulated conductor (A, B, C, D) in a helical relationship around the core (22) to define a plurality of insulated windings; and removing a portion of the insulation from at least one of the windings to define at least one electrode (#1, #2, #3, #4).
