1. A balloon catheter comprising:

  • a inflatable balloon comprising a balloon wall defining an interior volume, the balloon further comprising a distal end, a proximal end, and a central portion disposed therebetween;

    a catheter comprising an elongated shaft extending along an axis between a distal end portion and a proximal end portion, the proximal end portion comprising a connector configured to engage an inflation device, the distal end portion fixedly connected to the proximal end of the balloon, and a lumen extending though the shaft and in fluid communication with the interior volume of the balloon; and

    a stiffening member extending distally from the distal end portion of the catheter and through the interior volume of the balloon, the stiffening member being non-fixedly connected to the distal end of the balloon, wherein movement of the distal end of the balloon relative to the proximal end of the balloon is not restrained by the catheter, wherein axial movement of the distal end of the balloon relative to the proximal end of the balloon in a direction generally parallel to the axis of the shaft is not restrained by the stiffening member, and wherein transverse movement of the distal end of the balloon relative to the proximal end of the balloon in a direction generally perpendicular to the axis of the shaft is restrained by the stiffening member.
