Catheter having a high torque capability adapted to be inserted into and through a lumen of a blood vessel comprising a flexible elongate tubular shaft having proximal and distal extremities. The shaft is comprised of a torque tube extending substantially the entire length of the shaft. The torque tube has a cylindrical wall with at least one flexible portion therein with the flexible portion being characterized in that at least one slot is provided in the cylindrical wall subtending an angle of less than 360.degree.. A flexible sleeve encloses the torque tube and serves to cover the flexible portion while permitting the torque tube to bend in the vicinity of the slot a predetermined amount which is less than that which would create a permanent strain in the torque tube.
