Abstract
A composite wire guide shaft includes first and second sets of fibers which are arranged along a longitudinal axis and are embedded in an epoxy matrix. The first set of fibers are arranged substantially parallel to the longitudinal axis of the wire guide shaft and the remaining second set of fibers are helically wound in opposing directions about the longitudinal axis. The longitudinally parallel fibers provide pushability to the wire guide shaft while the helically wound fibers provide rotational stiffness for improved torqueability.
