Patent ID: 8454502

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: the seal anchor member being 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 having proximal and distal ends and defining 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 sealed relation with the object, and wherein the at least one port includes an undercut configured to collect gas that leaks through a substantially fluid-tight seal between the object and the at least one port.
