- 4. The multiple stapling device of claim 1, further comprising an anvil bolster in communication with said stapler anvil and wherein said prosthesis includes a prosthesis bolster near said distal end of said outer housing, said anvil bolster and said prosthesis bolster being incorporated with the prosthesis, the vessel and the staples upon anastomosis.
- 5. The multiple stapling device of claim 4, wherein the staples are adapted to form rings and said bolsters substantially fill the annular space created by said rings.
- 6. The multiple stapling device of claim 4, wherein said plurality of shaped channels are situated with radial symmetry about said longitudinal axis.
- 7. The multiple stapling device of claim 4, further comprising an obdurator advancement mechanism, said obdurator advancement mechanism comprising a geared shaft extending from said obdurator to said proximal end of said housing and a geared dial in communication with said geared shaft and said exterior of said outer housing, wherein rotation of said geared dial moves said obdurator in a predetermined direction.
- 8. The multiple stapling device of claim 7, wherein said shaft is adapted to extend through the body.
- 9. The multiple stapling device of claim 8, wherein said shaft includes demarcations to indicate the general location of the obdurator.
- 10. The multiple stapling device of claim 4, wherein said prosthesis bolster is formed from said prosthesis.
- 11. The multiple stapling device of claim 4, wherein said prosthesis bolster is attached to said prosthesis.
- 12. The multiple stapling device of claim 4, wherein at least one of said prosthesis bolster and said anvil bolster are impregnated with a haemostatic agent.
- 13. The multiple stapling device of claim 4, further comprising and anvil closure lever in communication with said body, said anvil closure lever adapted to advance said at least one anvil toward said distal end of said outer housing when rotated in a first direction and away from said distal end of said outer housing when rotated in a second direction.
- 14. The multiple stapling anastomosis device of claim 4, further comprising an anvil closure sheath, said anvil closure sheath capable of being positioned over said at least one stapler anvil to place said at least one anvil bolster in communication with said vessel.
- 15. A synthetic prosthesis for anastomosis within the human body having a proximal end and a distal end, said prosthesis further comprising a bolster at said distal end.
- 16. The synthetic prosthesis of claim 15, wherein said prosthesis is formed from either Dacron or PTFE.
- 17. The synthetic prosthesis of claim 15, wherein said bolster is formed from Teflon, said bolster being in communication with said prosthesis.
- 18. The synthetic prosthesis of claim 15, wherein said bolster is formed from the rolling of said prosthesis.
- 19. The synthetic prosthesis of claim 15, wherein said bolster is impregnated with a haemostatic agent.
- 20. A multiple stapling device for attachment of a prosthesis to a vessel comprising:
a body having a plurality of staple channels extending therethrough; a plurality of straight wire segments, one of each said straight wire segments disposed within each of said staple channels; a plurality of staple drivers, one of each said staple drivers disposed within each of said staple channels in communication with said straight wire segments; wherein said straight wire segments may be simultaneously driven from said staple channels by said staple drivers to form ring-shaped staples to anastomose a prosthesis to a vessel.
- 21. The multiple stapling device of claim 20, wherein said body further comprises a longitudinal centerline and said channels are spaced with radial symmetry about said longitudinal centerline.
- 22. The multiple stapling device of claim 20, wherein said staple channels terminate at a distal end of said body, said multiple stapling device further comprising a stapler anvil situated about said body, said stapler anvil adapted to place a bolster in proximity with said distal end of said body such that said ring-shaped staples are in communication with said bolster when discharged.
- 23. A method of anastomosis between a vessel and a prosthesis utilizing a stapler having a trigger for firing staples, a staple obdurator for forming staples from wire segments, and a stapler anvil for securing a bolster thereto, said method comprising:
placing a prosthesis around the stapler; placing the stapler adjacent a cavity formed in a vessel; advancing the obdurator into the vessel; moving the stapler anvil such that the bolster is in proximity to the obdurator; moving the trigger to advance the wire segments along the obdurator to form a series of ring-shaped staples through the vessel and the prosthesis, the ring-shaped staples capturing the bolster within the annular space created thereby.
- 24. The method of claim 23, wherein the prosthesis further comprises a prosthesis bolster and the step of moving the trigger to advance the wire segments further comprises capturing the prosthesis bolster within the annular space created by the ring-shaped staples.
- 25. The method of claim 24, wherein the stapler further comprises an anvil closure sheath, said method further comprising:
closing said anvil closure sheath to move the bolster in proximity to the obdurator.
- 26. A multiple stapling-device comprising:
a housing adapted for storing a plurality of straight wire segments therein, said housing having a plurality of exit areas for discharge of said straight wire segments therethrough; an actuating assembly adapted for discharging said plurality of straight wire segments through said plurality of exit areas; and, a prosthesis situated about said housing, said prosthesis having a bolster arranged at said exit areas; wherein said straight wire segments are formed into ring-shaped staples piercing said prosthesis and in communication with said bolster when discharged.
