Abstract:
1. A steerable catheter comprising: an elongated catheter body; a deflectable intermediate section comprising an integrated tubing construction with at least two off-axis lumens defining a plane of deflection, the deflectable intermediate section further comprising at least two bias members extending longitudinally and non-linearly along the intermediate section at opposing locations defining a transverse axis that is generally perpendicular to the plane of deflection; a first puller wire extending through a first lumen of the at least two off-axis lumens, and a second puller wire extending through a second lumen of the at least two off-axis lumens; a control handle at the proximal end of the catheter body; wherein the deflectable intermediate section is biased by the bias members to remain generally within the plane of deflection.
