A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity. The apparatus may include a seal anchor member comprising a compressible material. The seal anchor member may be adapted to transition between a first condition for insertion of at least a portion of the seal anchor member within a tissue tract and a second condition to facilitate a securing of the seal anchor member within a tissue tract and in substantial sealed relation with tissue surfaces defining a tissue tract. The seal anchor member may have proximal and distal ends and may define at least one port extending between the proximal and distal ends, the at least one port 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 scaled relation with the object. The seal anchor member may include indicia that indicates to a user a location at which the member may be cut so as to reduce the size of the member. |
