Claim:
1. A surgical access device comprising: an obturator comprising: an elongate shaft extending along a longitudinal axis between a proximal end and a distal end; the elongate shaft defining a first lumen and having an opening at the proximal end; the first lumen having a first lumen diameter that is sized and configured to receive an optical instrument having a distal end adapted to receive an image; and a transparent distal tip disposed at the distal end of the elongate shaft and adapted to permit passage of an image; at least part of the distal tip having a generally tapered configuration and an outer surface adapted for penetrating tissue; an elastomeric element disposed at the proximal end of the elongate shaft; the elastomeric element having an inner diameter that is smaller than the first lumen diameter of the elongate shaft; the elastomeric element being configured to frictionally engage an optical instrument inserted into the first lumen and restrain the optical instrument inserted into the first lumen from moving axially relative to the obturator.
