Patent ID: 8864659

Claim:
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises: 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 defining a central longitudinal axis and having leading and trailing ends, and at least one longitudinal object port extending between the leading and trailing ends and being adapted for reception of a surgical object whereby the compressible material defining the at least one longitudinal object port is adapted to deform to establish a substantial sealed relation with the surgical object, the seal anchor member including at least two removable anchor segments dimensioned to be positioned in adjacent stacked relation to selectively alter a longitudinal length of the seal anchor member to accommodate tissue tracts of different lengths, each anchor segment defining longitudinal object port segments adapted to be aligned when in the adjacent stacked relation to define the at least one longitudinal object port of the seal anchor member, wherein the seal anchor member includes a supplemental longitudinal opening extending along the full longitudinal length of the seal anchor.
