Abstract
An improved catheter system having a rollable electrode at its tip section capable of treating a tissue of a patient. A catheter suitable for radiofrequency ablation of cardiac tissues comprises a catheter shaft having a distal section with an open groove, a distal end, a proximal end and at least one lumen extending therebetween, wherein a rollable electrode secured onto a moving wire is disposed at the tip section of the said catheter to treat the tissue. In one embodiment, the rollable electrode is moved forward and/or backward while the RF energy is delivered through the rollable electrode to the tissue, creating a true linear lesion without dragging the catheter.
