Claim 20:
21. A surgical access device comprising:
an elongated tubular body having a proximal end and a distal end and having a lumen extending along a longitudinal axis between the proximal and the distal ends, wherein the proximal end of the elongated tubular body has an inner diameter greater than an inner diameter of the distal end;
at least one irradiation element positioned along the elongated tubular body and oriented to direct radiant energy toward the lumen, the irradiation element positioned outside the elongated tubular body; and
wherein the at least one irradiation element is positioned at an end of an opening in a wall of the elongated tubular body, wherein the opening in the wall extends through the wall at a non-perpendicular angle to the lumen to permit ultraviolet light to illuminate an interior portion of the lumen at an angle, such that the ultraviolet light is directed more toward the distal end of the lumen than the proximal end of the lumen.
