A delivery apparatus includes a steerable shaft having a pull-wire conduit. A pull wire extends through the pull-wire conduit. The steerable shaft includes one or more layers. A compression-resistance portion is incorporated into at least one of the one or more layers. A cross-section of the compression-resistance portion has an arcuate shape that extends along a portion of a cross-section of the steerable shaft. The compression-resistance portion has a hardness that is greater than a hardness of the one or more layers that the compression-resistance portion is incorporated into.
