Preformed catheter set for use with a linear ablation system to produce ablation lines in the left and right atrium for treatment of atrial fibrillation

摘要

A preformed catheter set for production of linear ablation lines in the left and right atrium for treatment of atrial fibrillation includes 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.
