A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity includes a seal anchor member comprising a compressible material and being adapted to transition between a first expanded condition to facilitate securing of the seal anchor member within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract and a second compressed condition to facilitate at least partial insertion of the seal anchor member within the tissue tract. The seal anchor member has proximal and distal ends defining elongated perimeters. At least one port extends between the proximal and distal ends and is adapted for reception of an object whereby compressible material defining the at least one port is adapted to deform to establish a substantial sealed relation with the object.
