ABSTRACT:
A surgical access apparatus includes a housing, an access member extending from the housing and having a longitudinal passageway for passage of an object and defining trailing and leading ends and an elongated seal mechanism mounted relative to the housing. The elongated seal mechanism includes a trailing hub and a leading hub longitudinally spaced from the trailing hub, and being adapted for relative rotational movement about the longitudinal axis, a plurality of spokes extending between and connected to the trailing hub and the leading hub, and an elongated seal member disposed within the spokes and adapted to establish a sealing relation about the object. The spokes define a first minimum internal dimension in a first condition thereof in the absence of an object and defining a second minimum internal dimension in a second condition thereof upon insertion of the object and relative rotation of the trailing hub and the leading hub. The second minimum internal dimension is greater than the first minimum internal dimension. The at least two of the spokes are generally obliquely arranged at a first angle relative to the longitudinal axis when in the first condition thereof and are adapted to be generally arranged at a second angle relative to the longitudinal axis when in the second condition thereof, the second angle being less than the first angle.
