A surgical access device includes a surgical sleeve defining a central longitudinal axis and having a longitudinal passageway to permit passage of a surgical object, and a diameter reduction assembly operably couplable to the surgical sleeve. The diameter reduction assembly includes a structure foundation and at least three stand-off elements mounted to the structure foundation. Each stand-off element is positioned to engage the surgical object and is independently movable relative to the remaining stand-off elements. The at least three stand-off elements are normally biased to a first position which urges the surgical object into general alignment with the central longitudinal axis, and are adapted for distal pivotal movement from the first position to a second position to facilitate passage of the surgical object, and for proximal pivotal movement from the first position to a third position to facilitate withdrawal of the surgical object.
