EXPANDABLE THORACIC ACCESS PORT A surgical access assembly (100) includes a body (105) having first and second body members (110, 120). Each body member (110, 120) has an opposed side (112, 122) and an outer side (113, 123). The body members (113, 123) are coupled to one another by a connector (108) and are moveable with respect to one another between an approximated position and a spread position wherein the opposed sides (112, 122) are flexed outwardly and apart from one another to define a passageway (190) therebetween. A flexible membrane (140) is coupled to the first and second body members (110, 120) and extends to therefrom such that translating the flexible membrane (140) radially outwardly moves the body members (110, 120) from the approximated position to the spread position. ,--100 ,-100 130 153a,b 153 154 153a,b 144 .154a,b 140d 140b 142 149 140a "R" 1283 "N" "R" 126 190 116 119 T"119 127 FIG. 3 117 |
