Abstract
A surgical access assembly includes a body having first and second side panels opposing one another and first and second end panels interconnecting the side panels. The first and second end panels are moveable between a folded position and an expanded position to correspondingly move the first and second side panels with respect to one another between an approximated position and a spaced apart position. In the spaced apart position, the first and second side panels are flexed outwardly and apart from one another to define a passageway therebetween. A flexible membrane is coupled to the first and second side panels and extends proximally therefrom.
