Expandable thoracic access port

摘要

A surgical access assembly (100) includes a body (110) having first and second side panels (112,122) opposing one another and first and second end panels (132,142) 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 (170) is coupled to the first and second side panels and extends proximally therefrom.
