Abstract
An access apparatus for use during a surgical procedure to provide access to the interior of the body includes an access member defining a longitudinal axis and having a proximal end for being disposed at an exterior side of the body and a distal end for extending into the interior of the body. The access member has a bore therethrough dimensioned to permit passage of an object. A seal is disposed within the bore of the access member. The seal includes a fabric material and an elastomeric material, and defines an internal passageway dimensioned to form a substantial sealing relation with an object inserted therethrough.

21. A cannula assembly for use in a surgical procedure, comprising:
-
a) a cannula member defining a longitudinal axis, the cannula member defining a longitudinal bore therethrough for passage of a surgical instrument;
b) a cannula housing defining an opening for receipt of the instrument, the cannula housing being connected to a proximal end of the cannula member so that the opening and the bore communicate with one another; and
c) a sealing member mounted within the cannula member for forming a substantial seal with the instrument, the sealing member comprising a fabric material, the fabric material comprising a plurality of strands, and an elastomeric material. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A surgical access apparatus for providing access to the interior of the body, which comprises:
-
an access member defining a longitudinal axis and having a proximal end for being disposed at an exterior side of the body and a distal end for extending into the interior of the body, the access member having a longitudinal passage extending therethrough;
an elongated seal coaxially mounted within the passage of the access member to define an outer passageway between the access member and the elongated seal, the seal comprising a fabric material, and an elastomeric material, the seal having a longitudinal passageway for receipt of an object therethrough in substantial sealed relation therewith; and
at least one of the access member and the elongated seal defining a port to permit communication of insufflation gases between the outer passageway and the longitudinal passage of the seal. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
