1. A device for performing a surgical procedure comprising:

  • an outer member extending along a central longitudinal axis and comprising an inner surface defining a first passageway;

    an inflatable member having a proximal end coupled to the outer member, the inflatable member including an inner surface defining a chamber;

    an inner member positioned within the first passageway and the chamber such that a distal end of the inner member is coupled to a distal end of the inflatable member, the distal end of the inner member comprising a stopper positioned such that the axis intersects an end wall of the stopper, the inner member having an inner surface defining a second passageway; and

    a support member movably disposed within the second passageway,wherein translation of the support member along the axis in a first direction causes the device to move between a first position in which a distal end of the support member is spaced apart from the stopper and the inflatable member has a first length and a second position in which the distal end of the support member is positioned within the stopper and the inflatable member has a second length, the second length being greater than the first length.
