Abstract
A surgical access assembly includes a body having first and second body members. Each body member has an opposed side and an outer side. The body members are coupled to one another by a connector and are moveable with respect to one another between an approximated position and a spread position wherein the opposed sides are flexed outwardly and apart from one another to define a passageway therebetween. A flexible membrane is coupled to the first and second body members and extends therefrom such that translating the flexible membrane radially outwardly moves the body members from the approximated position to the spread position.
