33. A bowel retractor device, comprising:
a body portion that is configurable between a collapsed, non-planar configuration wherein said body portion is configured to be fully passed through a cannula and a second expanded planar configuration, said body portion comprising; a flexible collar defining a central area; a single flexible planar film coextensive with said central area and including a perimeter attached to said flexible collar; and at least one preformed opening through said flexible planar film wherein each said preformed opening is smaller that said central area such that each said preformed opening is completely bounded by portions of said flexible planar film. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41)

42. A bowel retractor device, comprising:
a body portion that is configurable between a collapsed, non-planar configuration wherein said body portion is configured to be fully passed through a cannula opening and a second expanded planar configuration that includes a size and shape that is larger than said cannula opening, said body portion comprising; a flexible annular collar defining a central area; a single flexible planar film coextensive with said central area and including an annular perimeter attached to said flexible annular collar; and at least one preformed opening through said flexible planar film wherein each said preformed openings is smaller that said central area such that each said preformed opening is completely bounded by portions of said flexible planar film. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49)

50. A bowel retractor device, comprising:
-
a bendable collar defining a central area, said bendable collar being selectively bendable between a planar configuration and non-planar configurations and be self-retained in such non-planar configurations; a flexible planar film coextensive with said central area and including a perimeter attached to said bendable collar; and at least one preformed opening through said flexible planar film wherein each said preformed opening is smaller that said central area such that each said preformed opening is completely bounded by portions of said flexible planar film. - View Dependent Claims (51, 52)
