Abstract

Embodiments of the present invention are directed to ablation catheter systems configured, for example, to ablate tissue adjacent an ostium of the pulmonary vein in a left atria of a heart. In one embodiment, an ablation catheter system includes a handle and a catheter coupled to the handle defining a lumen extending through a length of the catheter, the catheter including a distal end thereof. The ablation catheter system may also include an electrode coupled to the handle with lines extending through the lumen of the catheter, the electrode being configured to be constrained adjacent the distal end of the catheter and configured to be deployed from the distal end of the catheter to an expanded configuration.

First claim

What is claimed is:

1. A catheter system configured to heat tissue, the catheter system comprising:
a catheter extending between a proximal end and a distal end and defining a lumen extending through a length thereof;
an RF energy source operatively coupled with the catheter; and
an electrode having an electrode frame coupled to the RF energy source and configured to be positioned adjacent the distal end of the catheter, the electrode frame configured to receive RF energy for…
