Claims
- 1. A temporary anastomosis device for achieving patency and eliminating fluid loss in a damaged vessel of the body, said device comprising:
a shunt comprising at least one elongate tube with second and first ends and inner and outer surfaces; and at least one clamp adapted to secure the vessel around the outer surface of the shunt; wherein the first end of the shunt is adapted for insertion into the damaged vessel or lumen tissue structure, and the clamp is sized and dimensioned to surround the vessel around the first end of the shunt, and said clamp is operable to secure the vessel to the shunt to create a substantially fluid-tight seal.
- 2. The device of claim 1 further comprising at least one obturator located at the first end of the shunt, said obturator having a tip adapted for insertion into the vessel.
- 3. The device of claim 1 wherein the first end of the shunt is angled for insertion of the shunt into the vessel.
- 4. The device of claim 2 wherein the outer surface of the shunt comprises a frictional gripping surface.
- 5. The device of claim 2 wherein the shunt is loop shaped.
- 6. The device of claim 2 wherein the shunt is Y-shaped.
- 7. The device of claim 2 wherein the obturator further comprises at least one wire strut that protrudes from the obturator.
- 8. The device of claim 7 wherein the wire strut is retractable into the shunt.
- 9. The device of claim 2 wherein the obturator is tapered at the first end for insertion into the vessel.
- 10. The device of claim 2 wherein the clamp is spring-loaded.
- 11. The device of claim 2 wherein the clamp is an elastomeric rolled tube attached at one end to the second end of the shunt.
- 12. The device of claim 7 wherein the obturator has a rod attached at the second end and a handle attached to an end of the rod.
- 13. The device of claim 2 further comprising a side port on the outer surface of the shunt for injection or withdrawal of fluids or air.
- 14. The device of claim 2 wherein the obturator has apertures at the second and first ends for ingress and egress of fluid within the obturator.
- 15. A temporary anastomosis device for achieving patency and eliminating fluid loss in a severed vessel comprising:
a first shunt comprised of an elongate tube with second and first ends and inner and outer surfaces wherein a flange is attached at the second end of the shunt; a second shunt comprised of an elongate tube with second and first ends and inner and outer surfaces wherein a flange is attached at the second end of the shunt; a first obturator contained on the first end of first shunt; a second obturator contained on the first end of second shunt; a first clamp that secures the vessel around the outer surface of the first shunt; and a second clamp that secures the vessel around the outer surface of the second shunt; wherein the first shunt is adapted for insertion into a first portion of the severed vessel and the second shunt is inserted into a second portion of the severed vessel and wherein the flanges of the shunts are releasably engaged to each other.
- 16. The device of claim 15 wherein the outer surface of the shunts comprise frictional gripping surfaces.
- 17. The device of claim 15 wherein the first ends of the obturators angle outwardly.
- 18. The device of claim 17 wherein at least a portion of each obturator is comprised of a collapsible region.
- 19. The device of claim 18 further containing a lumen positioned axially within the obturator for the enclosure of the guidewire.
- 20. The device of claim 15 wherein the clamps are spring-loaded.
- 21. The device of claim 15 wherein the clamps are elastomeric rolled tubes attached at to the second ends of the shunts.
- 22. The device of claim 15 wherein the obturator further comprises at least one wire strut at that protrudes from the first end of the obturator.
- 23. The device of claim 22 wherein the wire strut is retractable into the shunt.
- 24. The device of claim 15 wherein the obturator is tapered at its first end for insertion into the vessel.
- 25. The device of claim 23 wherein the obturator has a rod attached at the second end and a handle attached to an end of the rod.
- 26. The device of claim 15 further comprising a side port on the outer surface of the shunt for injection or withdrawal of fluids or air.
- 27. The device of claim 15 wherein the obturator has apertures at the second and first ends for ingress and egress of fluid within the obturator.
- 28. A method of achieving temporary patency and eliminating fluid loss in a severed body vessel or lumen tissue structure comprising the steps of:
providing a shunt device having a elongate tube dimensioned and configured to be inserted into the vessel, said tube having second and first ends, inner and outer surfaces, and an obturator on the first end of the tube; preparing the damaged body vessel or lumen tissue site by drawing ends of the damaged vessel or lumen together and applying at least one vessel clip to maintain the damaged vessels or lumens in close proximity to each other; and inserting the first end of the tube into the vessel, securing a clamp about the vessel and then removing the clip.
- 29. The method according to claim 28 wherein the step of inserting the first end of the tube into the vessel includes removing the obturator prior to placement of the clamp and removal of the clip.
- 30. A method of achieving temporary patency and eliminating fluid loss in a damaged body vessel or lumen tissue structure comprising the steps of:
providing a shunt device having a elongate tube dimensioned and configured to be inserted into the vessel, said tube having second and first ends, inner and outer surfaces, and an obturator on the first end of the tube; inserting the first and second ends of the shunt into the damaged region and placing clamps around the vessel at the shunt ends to seal the vessel in the region of the damage; and de-airing the vessel and removing the clamps.
- 31. The method according to claim 30 wherein the step of inserting the ends of the tube into the vessel includes removing the obturator.
