The integrated anastomosis tool of claim 8, wherein said casing includes a stop defined thereon, and wherein said cam cylinder includes a notch configured to engage said stop. 10. The integrated anastomosis tool of claim 1, wherein at least a part of said first mechanism is moved along a first axis to create the opening in the vessel wall, and wherein said at least a part of said first mechanism is configured to move away from said first axis before said second mechanism deploys said anastomosis device. 11. The integrated anastomosis tool of claim 1, wherein at least a part of said first mechanism is moved along a first axis to create the opening in the vessel wall, and wherein at least a part of said second mechanism is moved from a position away from said first axis to align with said first axis before said second mechanism deploys said anastomosis device. 12. The integrated anastomosis tool of claim 1, further comprising a hollow introducer tip placed at least partially into the opening in the target vessel, wherein at least a portion of said first mechanism and at least a portion of said second mechanism pass through said introducer tip. 13. The integrated anastomosis tool of claim 12, wherein said introducer tip is expandable. 14. The integrated anastomosis tool of claim 1, wherein at least one of said first mechanism and said second mechanism is at least partially lubricated with a biocompatible lubricious substance. 15. The integrated anastomosis tool of claim 14, wherein said lubricious substance is sodium stearate. 16. An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising: a first mechanism configured to create an opening in the target vessel; a second mechanism configured to complete an anastomosis with the target vessel; and a single control configured to operate both said first mechanism and said second mechanism; wherein at least a part of said first mechanism is moved along a first axis to create the opening in the vessel wall, and wherein said at least a part of said first mechanism is configured to move away from said first axis before said second mechanism deploys said anastomosis device. 17. The integrated anastomosis tool of claim 16, wherein said first mechanism and said second mechanism are located outside the lumen of the graft vessel. 18. The integrated anastomosis tool of claim 16, wherein said single control is movable in a single direction to operate both said first mechanism and said second mechanism. 19. The integrated anastomosis tool of claim 16, further comprising a cam cylinder connected to said single control, said cam cylinder including at least one cam path. 20. The integrated anastomosis tool of claim 19, wherein said first mechanism and said second mechanism each include at least one cam follower configured to engage at least one said cam path on said cam cylinder. 21. The integrated anastomosis tool of claim 16, further comprising a hollow introducer tip placed at least partially into the opening in the target vessel, wherein at least a portion of said first mechanism and at least a portion of said second mechanism pass through said introducer tip. 22. The integrated anastomosis tool of claim 21 wherein said introducer tip is expandable. 23. The integrated anastomosis tool of claim 16, wherein at least one of said first mechanism and said second mechanism is at least partially lubricated with a biocompatible lubricious substance. 24. An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising: a first mechanism configured to create an opening in the target vessel; a second mechanism configured to complete an anastomosis with the target vessel; and a single control configured to operate both said first mechanism and said second mechanism; wherein at least a part of said first mechanism is moved along a first axis to create the opening in the vessel wall, and wherein at least a part of said second mechanism is moved from a position away from said first axis to align substantially with said first axis before said second mechanism deploys said anastomosis device. 25. The integrated anastomosis tool of claim 24, wherein said first mechanism and said second mechanism are located outside the lumen of the graft vessel. 26. The integrated anastomosis tool of claim 24, wherein said single control is movable in a single direction to operate both said first mechanism and said second mechanism. 27.
