Abstract: A guide wire includes an elongate core section and a flexible member disposed on the distal end, the flexible member including a first wire wound into an inner helical coil in a first direction and a second wire wound into an outer helical coil wrapped about the first helical coil in the opposite direction. The two combined helical coils add stiffness and torque transmission to the guide wire without sacrificing tactile feedback.
