1. A surgical access device, comprising:
- a surgical retractor for retracting an opening in a biological body wall, the surgical retractor having,a noncompliant outer ring having an annular axis;
a first, middle lumen extending along the annular axis;
a second, top lumen having a diameter smaller than a diameter of the first, middle lumen and a third, bottom lumen having a diameter smaller than the diameter of the first, middle lumen;
the noncompliant outer ring being adapted for juxtaposition with an outer surface of the biological body wall,a noncompliant hoop having a split and ends at the split being aligned and in a non-overlapping relationship with each other with the noncompliant hoop being disposed flushed within the first, middle lumen of the noncompliant outer ring operatively preventing overlap of the ends of the noncompliant hoop and maintaining alignment of the noncompliant hoop with the annular axis of the noncompliant outer ring,an inner ring adapted for juxtaposition with an inner surface of the biological body wall, anda sleeve coupling the outer ring to the inner ring, the sleeve being adapted to traverse the opening in the body wall,the noncompliant outer ring being adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal the opening in the body wall; and
a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor.

Abstract
A surgical access device has a surgical retractor having a noncompliant outer ring with an annular axis, an inner ring, and a sleeve coupling the outer ring to the inner ring. The noncompliant outer ring is adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal an opening in a biological body wall. The access device may include a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor. The outer ring of the surgical retractor has a cross-sectional shape that prohibits the lid from being partially or incorrectly coupled to the outer ring of the surgical retractor.

12. A surgical access device, comprising:
-
a surgical retractor for retracting an opening in a biological body wall, the surgical retractor having, a noncompliant outer ring having a split, an annular axis and a lumen extending along the annular axis, the noncompliant outer ring being adapted for juxtaposition with an outer surface of the biological body wall, a noncompliant hoop having a split and ends at the split being aligned and in a non-overlapping relationship with each other with the noncompliant hoop being disposed flushed within the lumen of the noncompliant outer ring operatively preventing overlap of the ends of the noncompliant hoop and maintaining alignment of the noncompliant hoop with the annular axis of the noncompliant outer ring, a coupler disposed between the split in the noncompliant outer ring and having portions extending into opposing ends of the noncompliant outer ring at the split of the noncompliant outer ring, an inner ring adapted for juxtaposition with an inner surface of the biological body wall, and a sleeve coupling the outer ring to the inner ring, the sleeve being adapted to traverse the opening in the body wall, the noncompliant outer ring being adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal the opening in the body wall; and a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor, wherein the outer ring of the surgical retractor having a cross-sectional shape that facilitates proper coupling of the lid to the outer ring of the surgical retractor. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
