A surgical apparatus (10, 20) for positioning within a tissue tract accessing an underlying body cavity, which comprises: a seal anchor member (100, 200), the seal anchor member (100, 200) having proximal and distal ends (102, 104) and defining at least one port (108, 208) extending between the proximal and distal ends (102, 104) for reception of an object; the seal anchor member comprising a compressible material such that: the seal anchor member (100, 200) is adapted to transition between a first expanded condition to facilitate a securing of the seal anchor member (100, 200) within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate an at least partial insertion of the seal anchor member (100, 200) within the tissue tract; and the at least one port (108, 208) is adapted to deform to establish a substantial sealed relation with the object; and wherein at least one of the proximal and distal ends (102, 104) exhibits an arcuate configuration to facilitate an insertion of the seal anchor member (100, 200) within the tissue tract; characterized in that in the expanded condition the perimeters of the proximal and distal ends (102, 104) are oblong such that the seal anchor member is configured to a rolled state to facilitate the positioning within a tissue tract accessing a narrow underlying body cavity. a seal anchor member (100, 200), the seal anchor member (100, 200) having proximal and distal ends (102, 104) and defining at least one port (108, 208) extending between the proximal and distal ends (102, 104) for reception of an object; the seal anchor member comprising a compressible material such that: the seal anchor member (100, 200) is adapted to transition between a first expanded condition to facilitate a securing of the seal anchor member (100, 200) within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate an at least partial insertion of the seal anchor member (100, 200) within the tissue tract; and the at least one port (108, 208) is adapted to deform to establish a substantial sealed relation with the object; the seal anchor member (100, 200) is adapted to transition between a first expanded condition to facilitate a securing of the seal anchor member (100, 200) within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate an at least partial insertion of the seal anchor member (100, 200) within the tissue tract; and the at least one port (108, 208) is adapted to deform to establish a substantial sealed relation with the object; and wherein at least one of the proximal and distal ends (102, 104) exhibits an arcuate configuration to facilitate an insertion of the seal anchor member (100, 200) within the tissue tract; characterized in that in the expanded condition the perimeters of the proximal and distal ends (102, 104) are oblong such that the seal anchor member is configured to a rolled state to facilitate the positioning within a tissue tract accessing a narrow underlying body cavity.
