a cover attached to the top end of said main body, and configured to provide a barrier between the interior region and the exterior region at the top end of said main body.
2. Apparatus according to claim 1 wherein said sidewalls of said main body are tapered inwardly from said top end to said bottom end.
3. Apparatus according to claim 1 wherein the interior region comprises saline so as to provide an air-free environment therein.
4. Apparatus according to claim 1 wherein the interior region comprises carbon dioxide so as to provide an air-free environment therein.
5. Apparatus according to claim 1 wherein the interior region comprises a solution of saline and carbon dioxide so as to provide an air-free environment therein.
6. Apparatus according to claim 1 wherein said main body comprises a flexible material.
7. Apparatus according to claim 6 wherein said flexible material comprises urethane.
8. Apparatus according to claim 1 wherein said cover is integral with said main body.
9. Apparatus according to claim 1 wherein the top end of said main body comprises a mount, and said cover is removably attachable to said mount on said main body.
10. Apparatus according to claim 9 wherein said mount is formed of a substantially rigid material.
11. Apparatus according to claim 10 wherein the material comprises polycarbonate.
12. Apparatus according to claim 1 wherein the passageway in said base comprises an opening formed therein prior to attachment to the functioning vascular system of the patient.
13. Apparatus according to claim 1 wherein the passageway in said base comprises an opening formed therein after said base is attached to the functioning vascular system of the patient.
14. Apparatus according to claim 1 wherein the securing means comprises a stitching cuff extending around a perimeter of said base.
15. Apparatus according to claim 1 wherein said cover comprises a port therein, said port being configured to permit access between said exterior region and said interior region of said main body.
16. Apparatus according to claim 1 wherein the port comprises a base for a Luer lock fitting.
17. Apparatus according to claim 1 wherein the port comprises an entire Luer lock fitting.
18. Apparatus according to claim 1 wherein the port comprises an instrument passageway.
19. Apparatus according to claim 18 wherein said instrument passageway comprises a penetrable seal.
20. Apparatus according to claim 1 wherein said cover comprises a substantially rigid material.
21. Apparatus according to claim 20 wherein said substantially rigid material comprises polycarbonate.
22. Apparatus according to claim 1 wherein the seal comprises a vacuum seal.
23. Apparatus according to claim 1 wherein the securing means comprises hooks.
24. Apparatus according to claim 1 wherein the securing means comprises an adhesive material.
25. Apparatus according to claim 1 wherein said base comprises a blade guide for forming the passageway from the interior region of said main body to the functioning vascular system.
26. Apparatus according to claim 1 wherein said base is selectively configurable between a first configuration and a second configuration, and wherein the passageway from the interior region of said main body to the functioning vascular system of the patient is substantially closed in the first configuration and the passageway from the interior region of said main body to the functioning vascular system of the patient is substantially open in the second configuration.
27. Apparatus according to claim 26 wherein said main body is selectively configured between the first configuration and the second configuration by squeezing opposed ends of said main body toward one another.
