ABSTRACT:
A surgical access device comprising an instrument access channel extending through an instrument seal and a shroud comprising an inverting region disposed distally of the instrument seal exhibits improved tear-resistance of the instrument seal from instrument manipulation, for example, instrument withdrawals. Some embodiments of the inverting region invert through the instrument seal on instrument withdrawal. Some embodiments of the inverting region induce at least a portion of the instrument seal itself to invert on instrument withdrawal.
