Device and method for tacking a prosthetic screen
A prosthetic screen tacking device includes a barbed filament with a perpendicular foot at one end and a loop at the other. The barbs are situated near the foot and angulated in such a manner that they permit movement of the device through tissue in one direction (toward the loop), but prevent movement in the opposite direction (toward the foot). Different barbs and feet are shown. Methods of using the device with or without an associated button are also disclosed.
1. A surgical tacking device suitable for the fixation of a prosthetic screen, said device comprising:
a filament having a first end and a second end;
a plurality of barbs arranged on said filament between said first and second ends, said barbs being configured and angulated to allow said filament to pass through body tissue when said first end is pulled but to prevent said filament from passing through body tissue when said second end is pulled; and
a loop on said first end of said filament.
2. The surgical tacking device according to claim 1 , wherein said barbs are arranged in side by side pairs.
3. The surgical tacking device according to claim 1 , wherein said barbs are arranged in an alternating configuration.
4. The surgical tacking device according to claim 1 , wherein said barbs are arranged in a random configuration.
5. The surgical tacking device according to claim 1 , wherein said barbs are conical structures.
6. The surgical tacking device according to claim 1 , further comprising a button arranged to slide over said barbs when moved over said filament from said first end toward said second end but unable to slide over said barbs when moved from said second end toward said first end.
7. The surgical tacking device according to claim 1 , further comprising a button configured to slide over said barbs when rotated to a first position but unable to slide over said barbs when rotated to a second position.
8. The surgical tacking device according to claim 1 , wherein said device is made of a biodegradable material.
9. The surgical tacking device according to claim 1 , wherein said filament, barbs and loop are formed in one piece.
10. The surgical tacking device according to claim 1 , further comprising: a foot on said second end of said filament, said foot arranged to prevent said second end of said filament from passing through a prosthetic screen.
11. The surgical tacking device according to claim 10 , wherein said foot is substantially linear in shape.
12. The surgical tacking device according to claim 10 , wherein said foot is substantially circular.
13. The surgical tacking device according to claim 10 , wherein said foot is substantially elliptical.
14. The surgical tacking device according to claim 10 , further comprising a button arranged to slide over said barbs when moved over said filament from said first end toward said second end but unable to slide over said barbs when moved from said second end toward said first end.
15. The surgical tacking device according to claim 10 , further comprising a button configured to slide over said barbs when rotated to a first position but unable to slide over said barbs when rotated to a second position.
16. The surgical tacking device according to claim 10 , wherein said device is made of a biodegradable material.
17. The surgical tacking device according to claim 10 , wherein said filament, barbs, loop and foot are formed in one piece.
18. A method for affixing a prosthetic screen to the wall of the abdomen, said method comprising:
attaching a plurality of surgical tacking devices to the screen, the tacking devices including a filament having a first end and a second end with a loop at said first end and a plurality of barbs between said first and second ends;
delivering the screen with attached tacking devices to the peritoneal cavity; and
pulling the loop of each tacking device through the abdominal wall so that the barbs of the device lodge in the abdominal wall and affix the prosthesis to the abdominal wall.
19. The method according to claim 18 , further comprising cutting said tacking devices at a point between said first and second ends.
20. The method according to claim 18 , wherein said step of delivering includes delivering the screen and attached tacking devices into the peritoneal cavity through a port site.
21. A method for affixing a prosthetic screen to the wall of the abdomen, said method comprising:
attaching a plurality of surgical tacking devices to the screen, the tacking devices including a filament having a first end and a second end with a loop at said first end, a foot at said second end, and a plurality of barbs between said first and second ends;
delivering the screen with attached tacking devices to the peritoneal cavity; and
pulling the loop of each tacking device through the abdominal wall.
22. The method according to claim 21 , further comprising:
cutting said tacking devices at a point between said first and second ends.
23. The method according to claim 21 , wherein:
said step of delivering includes delivering the screen and attached tacking devices into the peritoneal cavity through a port site.
24. A method for affixing a prosthetic screen to the wall of the abdomen, said method comprising:
attaching a plurality of surgical tacking devices to the screen, the tacking devices including a filament having a first end and a second end with a foot at said second end and a plurality of barbs between said first and second ends;
delivering the screen and attached tacking devices to the peritoneal cavity of the abdomen; and
pulling the filament of each tacking device through the abdominal wall so that the barbs of the device lodge in the abdominal wall and affix the prosthesis to the abdominal wall.
25. The method according to claim 24 , further comprising cutting said tacking devices at a point between said first and second ends so that when the surgical procedure is concluded in parts of the tacking devices penetrate into or through the skin.
26. The method according to claim 24 , wherein said step of delivering includes delivering the screen and attached tacking devices into the peritoneal cavity through a port site when performing laparoscopic hernia repair.
27. The method according to claim 24 , wherein said step of delivering includes delivering the screen and attached tacking devices into the peritoneal cavity when performing open hernia repair.
