1. A surgical access device, comprising:
a non-inflatable access port sized to span a thickness of an abdominal wall of a patient and adapted to permit access of a surgical instrument through an incision in the abdominal wall of the patient and into an abdominal cavity under insufflation, wherein the access port comprises a proximal portion, a distal portion, and an intermediate portion between the proximal portion and the distal portion, the proximal portion comprises a proximal flange, the distal portion comprises a distal flange, the intermediate portion comprises an outer surface, the outer surface has a dimension that is less than corresponding dimensions of the proximal and distal flanges, wherein the proximal flange, the distal flange, and the intermediate portion are monolithically formed, wherein the access port comprises Styrene-Ethylene/Butylene-Styrene, and a surgical instrument, wherein the surgical instrument is a trocar having a valve structure configured to inhibit the escape of gas through the trocar when in use in an operative position, wherein the access port is sized and adapted to be disposed within the abdominal wall in an operative position, wherein disposition of the access port within the abdominal wall maintains the access port in the operative position when the intermediate portion is disposed across the incision and positioned within the incision with the proximal flange disposed exteriorly of the abdominal wall and the distal flange disposed interiorly of the abdominal wall, and wherein the access port is adapted to form a seal with the surgical instrument positioned through an opening in the access port in the operative position. |
