Abstract

Bowel retractor devices. In various forms, the bowel retractor devices are configurable from a collapsed position wherein the retractor may be inserted through a trocar cannula or other opening in a patient'"'"'s body to a second expanded position wherein at least a portion of the patient'"'"'s bowel may be advantageously supported in a desired position.

Claims

1-32. -32. (canceled)

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.

34. The bowel retractor device of claim 33, wherein when said body portion is in said collapsed orientation, said flexile collar is in a twisted configuration.

35. The bowel retractor device of claim 34, wherein when said flexible collar is in said twisted configuration, said flexible collar resembles a figure eight.

36. The bowel retractor device of claim 33, wherein the flexible planar film includes first amount of elasticity and wherein said flexible collar includes a second amount of elasticity that differs from said first amount of elasticity.

37. The bowel retractor device of claim 36, wherein said second amount of elasticity is less than said first amount of elasticity.

38. The bowel retractor device of claim 33, wherein said flexible collar comprises a metal wire embedded around the perimeter of said flexible planar film.

39. The bowel retractor device of claim 33, wherein at least one of said at least one preformed openings comprises an elongated slot.

40. The bowel retractor device of claim 33, wherein at least one of said at least one preformed openings comprises a multiple pointed star-shaped opening.

41. The bowel retractor device of claim 33, wherein said at least one preformed opening comprises a plurality of rupturable perforations.

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.

43. The bowel retractor device of claim 42, wherein when said body portion is in said collapsed orientation, said flexile collar is in a twisted configuration.

44. The bowel retractor device of claim 43, wherein when said flexible collar is in said twisted configuration, said flexible collar resembles a figure eight.

45. The bowel retractor device of claim 42, wherein the flexible planar film includes first amount of elasticity and wherein said flexible collar includes a second amount of elasticity that differs from said first amount of elasticity.

46. The bowel retractor device of claim 45, wherein said second amount of elasticity is less than said first amount of elasticity.

47. The bowel retractor device of claim 42, wherein said flexible collar comprises a metal wire embedded around the perimeter of said flexible planar film.

48. The bowel retractor device of claim 42, wherein at least one of said at least one preformed openings comprises an elongated slot.

49. The bowel retractor device of claim 42, wherein at least one of said at least one preformed openings comprises a multiple pointed star-shaped opening.

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.

51. The bowel retractor device of claim 50, wherein said bendable collar comprises a metal wire embedded around the perimeter of said flexible planar film.

52. The bowel retractor device of claim 50, wherein said at least one preformed opening comprises a plurality of rupturable perforations.
