<p>A surgical access assembly for use during a surgical procedure includes a housing, an access member extending distally from the housing and being dimensioned for positioning within tissue and a seal assembly disposed within the housing. The seal assembly includes first and second seal components operatively coupled to each other. Each of the first and second seal components includes respective seal members defining a respective passage for passage of a surgical object. The first seal component is adapted for rotational movement about the longitudinal axis and relative to the second seal component. The first seal component may be capable of relative rotation between a first position, in which the passages of the first and second seal members are in substantial longitudinal alignment, and a second position in which the passages of the first and second seal members are radially offset to inhibit the communication of fluid through the seal assembly.</p> |
