ABSTRACT:
The invention relates to a catheter having a tube-like basic body with a distal end and a proximal end provided with a connecting member, at least one continuous channel and a flexible part at the distal end. In the flexible end section a pull wire, extending through the channel to the outside of the proximal end, can be attached eccentrically. The end section preferably includes an eccentrically positioned channel through which the pull wire or other bending member extends. The pull wire can be doubled back in a hook-shaped fashion at its end and the bent end-piece incorporated in a substantially diametrically opposite, eccentrically situated cavity. With a preferred embodiment the deflection of the end section can be varied with the aid of a sliding wire advanced further or less far in the end section. Also, a strip-like, longitudinally extending electrode of a helically wound coil can be included.
