11. A compression device for the anastomosis of hollow organs according to claim 4, wherein each of said first, second and third collapsible members, respectively, comprises a plurality of resilient hinge portions disposed thereon to facilitate the collapsibility thereof.

12. A compression device for the anastomosis of hollow organs according to claim 11, wherein at least one of said resilient hinge portions is disposed along an inner surface of at least one of said first, second or third collapsible members.

13. A compression device for the anastomosis of hollow organs according to claim 11, wherein at least one of said resilient hinge portions is disposed along an outer surface of at least one of said first, second or third collapsible members.

14. A compression device for the anastomosis of a tubular hollow organ, according to claim 4, wherein a gap is formed between an end portion of each of said first and second collapsible members when said first, second and third collapsible members are joined.

15. A compression device for the anastomosis of a tubular hollow organ, according to claim 14, further comprising adjusting means disposed on at least one of said first, second or third collapsible members, for adjusting the size of said gap formed between said first and second collapsible members.

16. A compression device for the anastomosis of hollow organs according to claim 15, wherein said adjusting means includes first and second engaging portions disposed on said second collapsible member adapted for engaging said first and third collapsible members.

17. A compression device for the anastomosis of hollow organs according to claim 16, wherein each said first and third collapsible members have a plurality of sidewalls and at least one projecting portion extending from at least one of said sidewalls, said projecting portions being adapted for cooperatively mating with said either said first or said second engaging portions of said second collapsible member.
