Abstract

An apparatus for supplying surgical buttress material to a surgical stapler is provided. The apparatus has a pivotable area for attaching surgical buttress material. The apparatus may also have an adhesive and a release liner disposed over the buttress material.

Claims

1. An apparatus for applying surgical buttress material to a surgical stapler comprising:

a base member comprising at least a first side and a second side;

a first tensioning member extending outwardly from said first side;

a second tensioning member spaced apart from said first tensioning member and extending outwardly from said first side;

a surgical buttress material disposed over said base member wherein at least a portion of opposing edges of said surgical buttress material is coupled to at least a portion of said first and second tensioning members; and

wherein said surgical buttress material is maintained under tension by said first and second tensioning members prior to application.

2. The apparatus of claim 1 wherein said surgical buttress material further comprises perforations along said opposing edges of said surgical buttress material.

3. The apparatus of claim 1 wherein said surgical buttress material is coupled to said first and second tensioning members by posts extending outwardly from said first and second tensioning members.

4. The apparatus of claim 1 wherein said base member further comprises an alignment mechanism.

5. The apparatus of claim 1 further comprising a handle coupled to the base member.

18. A method for releasably affixing surgical buttress material to a surgical stapler comprising the steps of:

a) obtaining an apparatus according to claim 2;

b) inserting the apparatus between open stapler arms;

c) orienting the stapler arms so that the surgical buttress material is in position to be applied to the arms of the stapler upon contact there between;

d) closing stapler arms upon the surgical buttress material

e) applying pressure sufficient to tear the surgical buttress material along said perforations

f) opening the stapler arms; and

g) removing the apparatus from contact with the stapler arms.

6. An apparatus for applying surgical buttress material to a surgical stapler comprising:

a flexible, substantially planer base member with a first predetermined width, a first surface and a second surface; and

a surgical buttress material with a second predetermined width, wherein said second predetermined width is less than that of said first predetermined width,

wherein at least a portion of opposing edges of the surgical buttress material are coupled to at least a portion of opposing edges on said second surface of said base member, and

wherein the base member is maintained in a substantially u-shaped configuration by said surgical buttress material prior to application.

7. The apparatus of claim 6 wherein said surgical buttress material further comprises perforations along said opposing edges of said surgical buttress material.

8. The apparatus of claim 6 wherein said surgical buttress material is coupled to said base member by posts extending outwardly from said second surface of said base member.

9. The apparatus of claim 6 wherein said base member further comprises an alignment mechanism.

10. The apparatus of claim 6 further comprising a handle coupled to the base member.

19. A method for releasably affixing surgical buttress material to a surgical stapler comprising the steps of:

a) obtaining an apparatus according to claim 7;

b) inserting the apparatus between open stapler arms;

c) orienting the stapler arms so that the surgical buttress material is in position to be applied to the arms of the stapler upon contact there between;

d) closing stapler arms upon the surgical buttress material

e) applying pressure sufficient to tear the surgical buttress material along said perforations

f) opening the stapler arms; and

g) removing the apparatus from contact with the stapler arms.

11. An apparatus for applying surgical buttress material to a surgical stapler comprising:

a base member comprising a void, an elastic portion and a surgical buttress material wherein said base member is coupled to said surgical buttress material at the elastic portion and wherein said surgical buttress material is disposed across said void and is maintained under tension prior to application.

12. The apparatus of claim 11 wherein the base member comprises said elastic component.

13. The apparatus of claim 11 wherein the surgical buttress material comprises said elastic component.

14. The apparatus of claim 11 wherein said buttress material further comprises perforations within an area of the buttress material disposed across said void.

16. The apparatus of claim 11 wherein said base member further comprises an alignment mechanism.

17. The apparatus of claim 11 further comprising a handle coupled to the base member.

15. (canceled)

20. (canceled)

21. An apparatus for applying surgical buttress material to a surgical stapler comprising a base member with a first side and a second side, a plurality of tensioning members extending outwardly from said first side, and a coupling mechanism arranged on said tensioning members for coupling a surgical buttress material to said apparatus.

22. The apparatus of claim 21 wherein said base member further comprises an alignment mechanism.

23. The apparatus of claim 21 further comprising a handle coupled to the base member.

24. An apparatus for applying surgical buttress material to a surgical stapler comprising:

a base member comprising at least a first side and a second side;

a first tensioning member extending outwardly from said first side to a first point;

a second tensioning member spaced apart from said first tensioning member and extending outwardly from said first side to a second point;

wherein the distance between said first and second point is greater in an uncoupled configuration than in a coupled configuration.

25. The apparatus of claim 24 wherein at least a portion of opposing edges of a surgical buttress material is coupled to at least a portion of both first and second tensioning members when the apparatus is in a coupled position.

26. The apparatus of claim 24 further comprising at least one hinge coupling said first tensioning member to said base member.

27. A method for releasably affixing surgical buttress material to a surgical stapler comprising the steps of:

a) obtaining an apparatus according to claim 24;

b) coupling a surgical buttress material to said apparatus;

b) inserting the apparatus between open stapler arms;

c) orienting the stapler arms so that the surgical buttress material is in position to be applied to the arms of the stapler upon contact there between;

d) closing stapler arms upon the surgical buttress material

e) applying pressure sufficient to separate the surgical buttress material from the apparatus;

f) opening the stapler arms; and

g) removing the apparatus from contact with the stapler arms.
