1. A method, comprising:
advancing a guide extension catheter comprising a push member, an elongate tube member including a lumen having a diameter larger than a maximum outer dimension of the push member, and a fixation mechanism into a guide catheter; and
inhibiting longitudinal movement of a guidewire relative to the guide catheter or the tube member, including increasing a size of the fixation mechanism to engage the guidewire against an inner surface of the guide catheter or against an inner surface of the tube member, wherein when the fixation mechanism is positioned proximal to the tube member, the guidewire is engaged against the inner surface of the guide catheter.
