The device of claim 2, wherein the extension comprises a shape memory material. 4. The device of claim 1, wherein the measuring member comprises a measuring tape. 5. The device of claim 4, wherein the measuring tape comprises a shape memory material. 6. The device of claim 1, wherein the measuring member comprises at least one of: a self-expanding material;a self-collapsing material. 7. The device of claim 1, wherein the blood vessel measuring device comprises: an extension;a connector attaching a first end of the measuring member to the extension, the connector comprising an opening dimensioned to receive a second end of the measuring member. 8. The device of claim 1, wherein the measuring member comprises a cylinder of shape memory material. 9. The device of claim 1, wherein the measuring member comprises at least one of: a circular shape;an elliptical shape. 10. A method comprising: inserting a measuring device into an incision in a patient, the measuring device comprising an adjustable measuring member and a handle, the measuring device extending in a plane perpendicular to a longitudinal dimension of the handle;wrapping the measuring member completely around a blood vessel of the patient;measuring a dimension of the blood vessel with the measuring member. 11. The method of claim 10, further comprising: placing the measuring member near the blood vessel in an expanded position;releasing the measuring member to allow the measuring member to collapse to a closed position around the blood vessel. 12. The method of claim 10, wherein the dimension is a circumference of the blood vessel. 13. The method of claim 10, wherein the dimension is a width of a region available for attaching a connector to the blood vessel. 14. The method of claim 10, wherein the measuring member is attached to a handle. 15. The method of claim 10, wherein a connector attaches a first end of the measuring member to an extension, and the connector comprises an opening dimensioned to receive a second end of the measuring member. 16. A blood vessel measuring device comprising: a handle;an extension, a first end of the extension being attached to the handle;a connector attached to a second end of the extension;a measuring member attached to the connector and oriented in a plane perpendicular to a longitudinal dimension of the extension, the measuring member having a free end, the measuring member being configured to overlap itself in a circumferential direction such that the free end is automatically movable to wrap around a blood vessel to measure a size of the blood vessel. 17. The device of claim 16, wherein the connector comprises an opening dimensioned to receive a second end of the measuring member. 18. The device of claim 16, wherein the measuring member comprises circumferential measuring marks for measuring a circumference of the blood vessel. 19. The device of claim 18, wherein the measuring member comprises width measuring marks for measuring a width of a region of the blood vessel. 20. The device of claim 19, wherein the region is suitable for attachment of a cardiovascular conduit system to the blood vessel. 21. The device of claim 16, wherein the extension comprises a shape memory material and the measuring member comprises a measuring tape. 22. A method comprising: inserting a measuring device into an incision in a patient, the measuring device comprising a measuring member;wrapping the measuring member around a blood vessel of the patient;measuring a dimension of the blood vessel with the measuring member;placing the measuring member near the blood vessel in an expanded position;releasing the measuring member to allow the measuring member to collapse to a closed position around the blood vessel. 23. The method of claim 22, wherein the dimension is a circumference of the blood vessel. 24. The method of claim 22, wherein the dimension is a width of a region available for attaching a connector to the blood vessel. 25. The method of claim 22, wherein the measuring member is attached to a handle. 26. The method of claim 22, wherein a connector attaches a first end of the measuring member to an extension, and the connector comprises an opening dimensioned to receive a second end of the measuring member. 27. A method comprising: inserting a measuring device into an incision in a patient, the measuring device comprising a measuring member;wrapping the measuring member around a blood vessel of the patient;measuring a dimension of the blood vessel with the measuring member;wherein a connector attaches a first end of the measuring member to an extension, and the connector comprises an opening dimensioned to receive a second end of the measuring member. 28. The method of claim 27, wherein the dimension is a circumference of the blood vessel. 29. The method of claim 27, wherein the dimension is a width of a region available for attaching a connector to the blood vessel. 30. The method of claim 27, wherein the measuring member is attached to a handle. 31. A blood vessel measuring device comprising: a handle;a measuring member attached to the handle, the measuring member having an adjustable size and being dimensioned to wrap around a blood vessel to measure a size of the blood vessel while the handle is arranged parallel with a longitudinal dimension of the blood vessel;an extension with first and second ends, the first end being attached to the handle and the second end being attached to the measuring member, and the extension comprises a shape memory material. 32. A blood vessel measuring device comprising: a handle;a measuring member attached to the handle, the measuring member having an adjustable size and being dimensioned to wrap around a blood vessel to measure a size of the blood vessel while the handle is arranged parallel with a longitudinal dimension of the blood vessel;wherein the measuring member comprises a measuring tape having a shape memory material. 33. A blood vessel measuring device comprising: a handle;a measuring member attached to the handle, the measuring member having an adjustable size and being dimensioned to wrap around a blood vessel to measure a size of the blood vessel while the handle is arranged parallel with a longitudinal dimension of the blood vessel;wherein the measuring member comprises at least one of a self-expanding material and a self-collapsing material. 34.
