- 7. The method of claim 5 wherein said marking further comprises grasping said sheath at said skin surface.
- 8. The method of claim 5 wherein said marking further comprises placing a marker around said sheath at said skin surface.
- 9. The method of claim 5 wherein said marking further comprises a depth indicator on said sheath.
- 10. The method of claim 5 further comprising measuring a distance from said marking to said bleed back hole.
- 11. The method of claim 5 wherein said withdrawing said dilator and said sheath further comprises applying external pressure to said blood vessel puncture site.
- 12. The method of claim 5 wherein said marking further comprises:
applying external pressure to said blood vessel puncture site; removing said dilator; and delivering a hemostasis promoting material to said blood vessel puncture site through said sheath.
- 13. A method for determining the location and depth of a blood vessel puncture site from a skin surface with a sheath positioned within a blood vessel, comprising:
inserting a control tip dilator into the sheath and said blood vessel; withdrawing said sheath until a blood flow no longer enters a distal end of said sheath; marking said sheath at a skin surface; and removing said sheath to determine the depth of said blood vessel puncture site.
- 14. The method of claim 13 wherein said withdrawing further comprises controlling the blood flow from said puncture site with said control tip dilator.
- 15. The method of claim 13 wherein said marking further comprises grasping said sheath at said skin surface.
- 16. The method of claim 13 wherein said marking further comprises placing a marker around said sheath at said skin surface.
- 17. The method of claim 13 wherein said marking further comprises a depth indicator on said sheath.
- 18. The method of claim 13 wherein said removing further comprises applying external pressure to said blood vessel puncture site.
- 19. The method of claim 13 further comprising measuring a distance from said marking to said distal end of said sheath.
- 20. The method of claim 13 wherein said marking further comprises:
applying external pressure to said blood vessel puncture site; removing said control tip dilator; and delivering a hemostasis promoting material to said blood vessel puncture site through said sheath.
- 21. A method for determining the location and depth of a blood vessel puncture site from a skin surface with a sheath positioned within a blood vessel, comprising:
applying external pressure to said blood vessel puncture site; withdrawing said sheath until a blood flow from said blood vessel no longer enters a distal end of said sheath, wherein said blood flow can not be seen from a vent tube; marking said sheath at a skin surface; and removing said sheath to determine the depth of said blood vessel puncture site.
- 22. The method of claim 21 wherein said marking further comprises grasping said sheath at said skin surface.
- 23. The method of claim 21 wherein said marking further comprises placing a marker around said sheath at said skin surface.
- 24. The method of claim 21 wherein said marking further comprises a depth indicator on said sheath.
- 25. The method of claim 21 further comprising measuring a distance from said marking to said distal end of said sheath.
- 26. A method for delivering a hemostasis promoting material to a blood vessel puncture site, through a sheath located within a blood vessel, comprising:
inserting a dilator into the sheath and said blood vessel, said dilator having a bleed back hole near a distal end of said sheath; withdrawing said dilator and said sheath until a blood flow from said blood vessel no longer enters said bleed back hole; applying external pressure to said blood vessel puncture site; removing said dilator; and delivering the hemostasis promoting material to said blood vessel puncture site through said sheath.
- 27. A method for delivering a hemostasis promoting material to a blood vessel puncture site, through a sheath located within a blood vessel, comprising:
inserting a control tip dilator into the sheath and said blood vessel; withdrawing said sheath until a blood flow no longer enters a distal end of said sheath; applying external pressure to said blood vessel puncture site; removing said control tip dilator; and delivering a hemostasis promoting material to said blood vessel puncture site through said sheath.
- 28. A method for delivering a hemostasis promoting material to a blood vessel puncture site, through a sheath located within a blood vessel, comprising: applying external pressure to said blood vessel puncture site;
withdrawing said sheath until a blood flow from said blood vessel no longer enters a distal end of said sheath; and delivering the hemostasis promoting material to said blood vessel puncture site.
- 29. The method of claim 28 further comprising releasing said external pressure.
- 30. An apparatus for determining the location and depth of a blood vessel puncture site from a skin surface, comprising:
a procedural sheath positioned within a blood vessel; a control tip dilator located within said procedural sheath such that a control tip of said control tip dilator is located external a distal end of said procedural sheath; a marking means on said procedural sheath; and a means for determining a bleed back flow.
- 31. The apparatus of claim 30 further comprising means for controlling a bleed back flow with said control tip dilator.
- 32. The apparatus of claim 30 wherein said marking means comprises a finger placement marker.
- 33. The apparatus of claim 30, wherein said marking means further comprises an o-ring.
- 34. The apparatus of claim 30 wherein said marking means further comprises a depth indicator.
- 35. An apparatus for determining the location and depth of a blood vessel puncture site from a skin surface, comprising:
a procedural sheath positioned within a blood vessel; means for applying external pressure to said blood vessel puncture site; means for determining a bleed back flow with a vent tube; and a marking means on said procedural sheath.
- 36. The apparatus of claim 35 wherein said marking means further comprises a finger placement marker on said procedural sheath at said skin surface.
- 37. The apparatus of claim 35 wherein said marking means further comprises an o-ring at said skin surface.
- 38. The apparatus of claim 35 wherein said marking means further comprises a depth indicator at said skin surface.
