ABSTRACT:
An electrode catheter comprising a tubular body with a distal section having a flexible tubular portion, wherein the flexible tubular distal section is covered by at least one spirally wrapped flat ribbon electrode. Each spirally wrapped flat ribbon electrode has an associated lead wire that can be connected to a source of energy for ablation or connected to a recording system to produce electrophysiologic signals for diagnosis. The preferred catheter is steerable by use of a puller wire connected to the distal section and connected to a handle with means for controlling the movement of the puller wire. In a preferred embodiment, the spirally wound flat ribbon electrode is partially masked with a polyurethane or latex mask.
