A cannula (

10

) for receiving surgical instruments for performing a surgical procedure on a body includes a tubular structure (

12

) defining a passage (

16

) through which the surgical instruments are inserted into the body. The tubular structure (

12

) includes an expandable portion (

40

) for enabling an increase in the cross-sectional area of the passage (

16

). The expandable portion (

40

) of the tubular structure (

12

) has a slot (

100

) and a guide member (

114

) disposed in the slot. The guide member (

114

) is movable from a first end (

102

) of the slot (

100

) toward a second end (

104

) of the slot to enable the cross-sectional area of the passage (

16

) to increase. The expandable portion (

40

) has a stop (

106

) between the first and second ends (

102

and

104

) of the slot (

100

) engageable with the guide member (

114

) to retain the guide member in a position relative to the slot and resist movement of the guide member from the position relative to the slot.
