A preformed catheter set for production of linear ablation lines in the left and right atrium for treatment of atrial fibrillation, comprising:
- at least a first catheter including a pre-shaped distal segment having a distal linear ablation antenna and a U-shaped curve portion proximal to the distal linear ablation antenna.
A method of producing linear ablation lines in the left and right atrium for treatment of atrial fibrillation, comprising:
- providing a preformed catheter set including at least a first catheter including a pre-shaped distal segment having a distal linear ablation antenna and a U-shaped curve portion proximal to the distal linear ablation antenna;
- deploying the preshaped distal segment in the left or right atrium so that the preshaped distal segment of the first catheter takes the U-shaped curve shape;
- linearly ablating the atrium with the distal linear ablation antenna to treat atrial fibrillation.
