Patent ID: 8192405

Claim:
A surgical access device for permitting access to body tissue, which comprises: a seal housing assembly; a first seal positioned within the seal housing assembly and including a proximal face and a distal face, the first seal including a resilient material and comprising at least one polymeric surface and at least one fabric surface positioned in juxtaposition with the at least one polymeric surface, the first seal including inner portions defining a first aperture extending therethrough and being adapted to expand from a first open condition to an expanded second open condition upon insertion of a surgical object, the inner portions of the first seal engaging the surgical object in the second open condition to establish a substantially fluid-tight seal therewith; a second seal positioned within the seal housing assembly distally of the first seal, the second seal including a substantially planar configuration and inner portions defining a second aperture extending therethrough, the second aperture being larger than the first aperture of the first seal; a cannula assembly extending distally from the seal housing assembly along a longitudinal axis, the cannula assembly being configured and dimensioned for introduction into body tissue and including a longitudinal passage configured and dimensioned to permit insertion of the surgical object; and a third seal positioned within the cannula assembly, the third seal being configured and dimensioned to substantially inhibit communication of fluid therethrough in the absence of the surgical object, wherein the at least one fabric surface is configured as at least one layer of fabric material embedded within the first seal, and the resilient material comprises at least two layers of resilient material, the at least one layer of fabric material being at least partially positioned between the at least two layers of resilient material.
