A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity including a compressible seal anchor member. The seal anchor member includes a leading portion that is expandable to facilitate transitioning between a first condition and a second condition. Insertion of the seal anchor member into a tissue tract is facilitated by the reduced dimensions of the leading portion while in the first condition. Anchoring of the seal anchor member within the tissue tract is facilitated by the expanded dimensions of the leading portion while in the second condition. |
