An anchor assembly (10) for retaining a cannula (14) or other medical instrument within a body cavity and including an inflatable member (18) selectively disposed between an expanded position and a collapsed position. A mounting assembly is cooperatively disposed and structured with a base (28), underlying the inflatable member, so as to mechanically attach the inflatabl e member to an exterior of the cannula. The mechanical attachment is accomplished by one or more retaining segments (40, 42) on the inflatable member being disposed in a compressed or sandwiched orientation between the base and the mounting assembly. |
