Abstract

A catheter includes a torque transmission assembly (28) coupled to an elongate body (10) wherein the torque transmission assembly can transmit torque along the elongate body. The elongate body includes a distal portion and an opposite proximal portion. The torque transmission assembly includes one or more segments along the elongate body. The torque transmission assembly ensures that a substantial fraction of the rotational and displacement forces provided along the elongate body are translated to rotational and displacement forces at the distal portion. An electrical connector is coupled to the wires and these wires (32, 36, 42) can conduct electrical current between the electrical connector and at least one of the distal portion and the one or more exposed segments.
