Abstract
An optical penetrating adapter for mounting to a surgical portal to permit visualization through the surgical portal includes an adapter member defining a longitudinal axis and having a transparent window adapted to penetrate tissue and to permit visualization therethrough and means for coupling the adapter member to the surgical portal. The transparent window may have various shapes and configurations adapted to penetrate, dissect, resect or separate tissue in a non traumatic manner. Alternatively, the transparent window may incorporate structure such as cutting edges blades, points, etc to pierce, cut or incise tissue.

1-20. (canceled)
A surgical system comprising:
- a member configured for use with a cannula sleeve, the member defining a central longitudinal axis, a distal portion of the member including a penetrating surface configured to facilitate advancement of the member through tissue, the member 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, each of the second surfaces intersecting one of the pair of first surfaces and extending proximally and contiguously therefrom;
- and
- a pair of third surfaces, each of the third surfaces intersecting one of the pair of second surfaces and extending proximally and contiguously therefrom;
- the penetrating surface including a rounded penetrating end face, the end face of the penetrating surface being offset from the central longitudinal axis of the member.
A member configured for use with a cannula sleeve, the member comprising:
- a penetrating surface configured to facilitate advancement of the member through tissue, the penetrating surface including:
- a pair of first surfaces extending proximally and contiguously from the penetrating surface and in a parallel relation to a central longitudinal axis of the member;
- a pair of second surfaces, each of the second surfaces intersecting one of the pair of first surfaces and extending proximally and contiguously therefrom, at least one of the pair of second surfaces diverging outwardly in a proximal direction relative to the central longitudinal axis to define a first angle;
- and
- a pair of third surfaces, each of the third surfaces intersecting one of the pair of second surfaces and extending proximally and contiguously therefrom, at least one of the pair of third surfaces diverging outwardly in a proximal direction relative to the central longitudinal axis to define a second angle greater than the first angle.
