Steerable catheter having a loop electrode

摘要

An electrophysiology catheter suitable for radiofrequency ablation of cardiac tissues comprises a proximal section, a catheter shaft section and a distal section whereby a distal loop electrode having a temperature sensor and a close-loop temperature control. A conducting wire extends through the lumen and is connected to the loop electrode. The steerable catheter having a loop electrode is inserted into the chambers of the heart to create a continuous, non-linear lesion by supplying radiofrequency energy to said conducting wire.
