Abstract

A catheter for use in radiofrequency ablation of the myocardium of the heart of a patient having a flexible elongate member with at least one lumen extending therethrough and having proximal and distal extremities. A needle-like electrode formed of a conducting material is mounted on the distal extremity of the flexible elongate member. A conductor extends through the lumen and is connected to the electrode. Radiofrequency energy is supplied to to said conductor and to the electrode to cause ablation of the myocardium.
