Patent ID: 8257252

Claim:
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises: a seal anchor member comprising a proximal end, a distal end, an intermediate portion extending between the proximal and distal ends, and a longitudinal axis defined between the proximal and distal ends, the seal anchor including a compressible material; the seal anchor member being adapted to transition between a first expanded condition and a second compressed condition, the first expanded condition facilitating a securing of the seal anchor member within the tissue tract and in substantial scaled relation with tissue surfaces defining the tissue tract, and the second compressed condition facilitating an at least partial insertion of the seal anchor member within the tissue tract; wherein the perimeters of the intermediate portion are elongated in a direction substantially orthogonal to the longitudinal axis when in the first expanded condition to facilitate the positioning of the seal anchor member within a tissue tract accessing a narrow underlying body cavity; the seal anchor member defining at least one port extending between the proximal and distal ends and being adapted for the 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; and wherein at least one of the proximal and distal ends exhibits an arcuate configuration to facilitate an insertion of the seal anchor member within the tissue tract.
