Claim:
A surgical cannula apparatus, which comprises: a cannula member defining a longitudinal axis and having proximal and distal ends; a seal member at least partially disposed within the cannula member, the seal member being generally elongated extending along the longitudinal axis of the cannula member, the seal member having an inner surface defining a passage and being adapted to form a substantial sealing relation with a surgical object introduced therethrough, the seal member defining proximal and distal seal ends, wherein the seal member comprises a fabric material and an elastomeric material; and a seal mount secured to the distal seal end of the seal member adjacent the distal end of the cannula member, the seal mount dimensioned for axial movement with the distal seal end of the seal member upon insertion of the surgical object through the seal member to permit expansion of the passage of the seal member while maintaining the substantial sealing relation with the surgical object.
