The elongated member (110) may define a passage (101) for passage of the surgical instrument. The elongated member (110) is adapted to assume a substantial rolled configuration in a normal unstressed condition thereof. The elongated member (110) may be adapted to substantially seal the passage (101) when in the rolled configuration thereof. As a further feature, the elongated 10 member (110) may be adapted to establish a substantial sealed relation with the surgical instrument received within the passage (101). In one embodiment, the elongated member (110) may include an elastomeric material which is adapted to permit angulated movement of the surgical instrument relative to the central axis (y). The elongated member (110) may include a leading end portion (11 Ob) which is substantially closed in 15 the absence of the surgical instrument to substantially seal the passage (10 1).
