Patent ID: 8545495

Claim:
A catheter comprising: an elongated flexible tubular catheter body having an axis and proximal and distal ends; an ablation assembly at the distal end of the catheter body having a preformed generally circular curve that is generally transverse to the axis of the catheter body, the ablation assembly comprising a flexible tubing and carrying a tip electrode at its distal end, the tip electrode having an asymmetric design, wherein a first side of the tip electrode extending longitudinally from a proximal end to a distal end of the tip electrode and being adapted to contact tissue extends radially beyond an outer wall of the flexible tubing and a second side of the tip electrode generally opposite the first side and extending longitudinally from the proximal to the distal end of the tip electrode is generally even with the outer wall of the flexible tubing; and an electrode lead wire extending through the catheter body and into the ablation assembly and having a distal end connected to the tip electrode.
