Abstract: A catheter with three distinct compression resistance coils, including a body coil and two pull wire coils, is disclosed. The triple coil system can provide maximal resistance to compression of the catheter's proximal shaft, as well as maximization of the curve angle that the catheter tip can achieve. Additionally, the tri-coil catheter can allow for a lower initial compression load and a more flexible proximal shaft. A gap between the outer diameter of the pull wire and the inner diameter of the pull wire compression coil that is equal to about 10-30% of inner diameter of the pull wire compression coil can provide optimal catheter performance.

Abstract: The instant disclosure relates to electrophysiology catheters for tissue ablation within a cardiac muscle. In particular, the instant disclosure relates to an ablation balloon and catheter shaft that deflects to conform to a shape of a target pulmonary vein receiving ablation therapy for a cardiac arrhythmia, for example. The deflection of the catheter shaft enables a lesion line along a circumference of the target pulmonary vein with improved consistency.
