1. A surgical access assembly for positioning within an opening in tissue, the surgical access assembly comprising:
- first and second wings disposed in opposed relation relative to one another, each wing including a body portion, a distal portion and first and second portions;
a first side wall section hingedly connecting the body portions of the first and second wings to one another at the first portion of each of the body portions and a second side wall section hingedly connecting the body portions of the first and second wings to one another at the second portion of each of the body portions, the side wall sections being movable between a first position, wherein the side wall sections are disposed within an outer dimension defined by the first and second wings, and a second position wherein each of the side wall sections are angled outwardly to extend from the outer dimension defined by the first and second wings; and
wherein, the first and second wings are moveable between an approximated position corresponding to the first position of the side wall sections and a spaced apart position corresponding to the second position of the side wall sections.

Abstract
A surgical access assembly includes first and second wings disposed in opposed relation relative to one another. Each wing includes a body portion, a distal portion and first and second portions. A side wall section hingedly connects the body portions of the wings to one another at the first portion thereof and at the second portions thereof. Each of the side wall sections is movable with respect to the other side wall sections between a first position and a second position wherein each of the side wall sections is angled with the first and second wings. The first and second wings are moveable between an approximated position corresponding to the first position of the side wall sections and a spaced apart position corresponding to the second position of the side wall sections.

12. A surgical access assembly for positioning within an opening in tissue, comprising:
-
first and second members having inner and outer walls and movably connected to one another, the first and second members being movable from a first position wherein the inner walls are closer to one another to a second position wherein the inner walls are further apart, the first and second members further having proximal and distal portions and first and second side portions defined between the proximal and distal portions; and a collapsible member connected to the first side portion of the first and second members to connect the first and second members, the collapsible member movable from a collapsed position, wherein the collapsible member is flexed inwardly towards the first and second members, to an expanded position, wherein the collapsible member is angled outwardly to extend from the first and second members. - View Dependent Claims (13, 14, 15, 16)
