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 at least one surgical instrument through an incision in the abdominal wall of the patient and into an abdominal cavity, wherein the access port comprises a proximal portion, a distal portion, and an intermediate portion between the proximal portion and the distal portion, wherein an opening extends through the access port between the proximal portion and the distal portion, anda 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 proximal portion comprises a proximal flange having a proximal flange diameter, wherein the proximal portion has a proximal surface portion and a distal surface portion, wherein the proximal surface portion at least partially defines a concave area,wherein the distal portion comprises a distal flange having a distal flange diameter,wherein the proximal flange, the distal flange, and the intermediate portion are monolithically formed of an elastomeric material, wherein the intermediate portion comprises an outer surface and at least one inner surface, the outer surface has a diameter that is less than the proximal and distal flange diameters, the inner surface at least partially defines the opening, andwherein 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 and forms a perimeter seal between the outer surface and the abdominal wall 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 the access port, wherein the intermediate portion conforms to the surface of the surgical instrument positioned through the opening and forms the seal between the inner surface and the surgical instrument.
