Abstract: The present invention provides a significantly improved guiding catheter for use in catheter systems. It utilizes a segmented body to tailor the catheter strength and flexibility for optimal responsiveness at the distal end. The segmented body utilizes progressively softer materials in the distal direction in order to improve overall maneuverability. The longest and proximalmost segment is substantially straight and harder or stiffer than the rest of the catheter and than typical guiding catheter bodies. This segment performs the function of a handle having a platform at its distal end in order to improve response in the distal segments of the remainder of the catheter. This invention improves the transmission of torque, axial and lateral forces and reduces the likelihood of kinking both laterally and radially. Achieved is improved control of the distal portion through input from the hub at the proximal end of the elongated stiff handle segment.
