Claim Text:
1. An optical penetrating system for permitting visualization comprising: a cannula sleeve including an internal longitudinal passage dimensioned to permit passage of surgical instrumentation; and an adapter member adapted for mounting directly to a distal end of the cannula sleeve, the adapter member defining a central longitudinal axis, and including an optical window with a distal end defining a penetrating surface configured to facilitate advancement of the adapter member through tissue, the optical window including a pair of first surfaces extending proximally and contiguously from the penetrating surface and in a parallel relation to the central longitudinal axis, a pair of second surfaces intersecting the pair of first surfaces, and extending proximally and contiguously therefrom, and a pair of third surfaces intersecting the pair of second surfaces, and extending proximally and contiguously therefrom, the penetrating surface of the optical window being arcuate in configuration and defining a rounded penetrating end face, the end face of the penetrating surface being offset from the central longitudinal axis of the adapter member.
