Abstract:
The invention relates to a steerable catheter having a distal section with reduced variation in deflection path during deflection. The distal section of the catheter includes stripes of different material hardness along the length of the distal section affecting the directionality of catheter deflection upon the application of a deflection force like that applied by pull wires. The stripes result in preferential bending in a desired path with greater reproducibility.
