Abstract
An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue

(canceled)
An optical access apparatus, comprising:
- an obturator sleeve defining a passageway, the passageway defining a longitudinal axis and configured to receive surgical instrumentation at least partially therethrough;
- and
- a tip disposed adjacent a distal end of the obturator sleeve and configured to separate tissue, the tip being rotatable about an axis of rotation parallel to the longitudinal axis between a first position where a distal end of the tip is in general alignment with the longitudinal axis and a second position where the distal end of the tip is offset from the longitudinal axis.
