| 摘要 |
This invention is an electrode catheter comprising a tubular body (11) with a distal section (13) having a flexible tubular portion, wherein the flexible tubular distal section (13) is covered by at least one spirally wrapped flat ribbon electrode (15). Each spirally wrapped flat ribbon electrode (15) has an associated lead wire (25) that can be connected to a source of energy of ablation or connected to a recording system to produce electrphysiologic signals for diagnosis. The preferred catheter is steerable by use of a puller wire (27) connected to the distal section (13) and connected to a handle (17) with means for controlling the movement of the puller wire (27). In a preferred embodiment, the spirally wound flat ribbon electrode (15) is partially masked with a polyurethane or latex mask (127).
