Abstract

Described are medical devices useful for applying a bolster material to a surgical fastening device such as a stapler, and related methods of manufacture and use. The devices include an applicator element for receipt between arms of the stapler, and a bolster material, desirably a remodelable extracellular matrix material, coupled to the applicator element. In certain embodiments, the bolster material is held by the applicator element, for example having at least a portion looped around or received through or over a portion of the applicator element. Also described are unique implantable materials including coatings of dried, reversible adhesive.

Claims (46)

1. A medical device useful for applying a bolster material to a surgical fastening device having a first arm and a second arm presenting respective first arm and second arm surfaces, the medical device comprising:

an applicator element comprising a compressible applicator sheet which is receivable between the first and second arms, said compressible applicator sheet having a first side, a second side, and an edge portion between the first side and second side;

a bolster material provided as a single piece that has a first bolster material portion presented at the first side of the applicator sheet, a second bolster material portion presented at the second side of the application sheet, and a third bolster material portion connecting the first bolster material portion and second bolster material portion and wrapped around the edge portion of the applicator sheet, wherein the compressible applicator sheet and the bolster material are coupled together such that the compressible applicator sheet and the bolster material by themselves are retained in association with one another for presenting said bolster material at least at said first side of said compressible applicator sheet for contact with said first arm surface, and wherein said bolster material and applicator element are constructed and arranged and are coupled together in such a manner that they can be de-coupled during compression of the medical device between the first and second arm surfaces of the surgical fastening device with said bolster material in contact with the first arm surface; and

a dried, reversible adhesive coating on said bolster material;

wherein said applicator element is sandwiched between said first bolster material portion and said second bolster material portion; and

wherein said bolster material has at least a portion received through said compressible applicator sheet.

2. The medical device of claim 1 , wherein the bolster material comprises collagen.

3. The medical device of claim 2 , wherein the bolster material comprises an extracellular matrix material.

4. The medical device of claim 3 , wherein the extracellular matrix material comprises submucosa.

5. The medical device of claim 4 , wherein the submucosa is small intestinal submucosa.

6. The medical device of claim 5 , wherein the small intestinal submucosa is porcine.

7. The medical device of claim 1 , wherein the compressible applicator sheet comprises a polymer foam.

8. The medical device of claim 1 , wherein said compressible applicator sheet includes at least one lateral portion adapted for grasping when the compressible applicator sheet is received between said arms.

9. The medical device of claim 1 , wherein said bolster material is presented at said first side and said second side of said compressible applicator sheet for contact with the first arm surface and the second arm surface, respectively.

10. The medical device of claim 1 , wherein the dried, reversible adhesive coating on said bolster material is arranged to adhere the bolster material to the first arm surface of the surgical fastening device.

11. A medical device for applying a bolster material to a surgical fastening device having opposed arm surfaces, comprising:

an applicator element comprising a compressible applicator sheet having at least one aperture;

a bolster material retained in association with the compressible applicator sheet; and

a dried, reversible adhesive coating on said bolster material;

wherein said bolster material has at least one portion received through the at least one aperture in the compressible applicator sheet, the compressible applicator sheet. and the bolster material being mechanically coupled together by said at least one portion received through the at least one aperture such that the compressible applicator sheet and the bolster material by themselves are retained in association with one another; and

wherein said bolster material and applicator element are constructed and arranged and are coupled together in such a manner that they can be de-coupled during compression of the medical device between the opposed arm surfaces of the surgical fastening device with said bolster material in contact with at least one of said opposed arm surfaces;

wherein said applicator element is sandwiched between faces of said first bolster material portion and said second bolster material portion; and

wherein said first and second bolster material portions have a width, a length, and a thickness, and said faces extend along said width and length; said width and length of said first and second bolster material portions each being greater than said thickness.

12. The medical device of claim 11 , wherein the dried, reversible adhesive coating on said bolster material is arranged to adhere the bolster material to the at least one of said opposed arm surfaces of the surgical fastening device.

13. The medical device of claim 11 , wherein the bolster material comprises collagen.

14. The medical device of claim 13 , wherein the bolster material comprises an extracellular matrix material.

15. The medical device of claim 14 , wherein the extracellular matrix material comprises submucosa.

16. The medical device of claim 15 , wherein the submucosa is small intestinal submucosa.

17. The medical device of claim 16 , wherein the small intestinal submucosa is porcine.

18. The medical device of claim 11 , wherein the compressible applicator sheet comprises a polymer foam.

19. The medical device of claim 11 , wherein said compressible applicator sheet includes at least one lateral portion adapted for grasping when the compressible applicator sheet is received between said arms.

20. A medical device for applying a bolster material to a surface of a surgical fastening device, comprising:

an applicator element comprising a compressible applicator sheet;

a bolster material, wherein the compressible applicator sheet and the bolster material are coupled together and thereby held in association with one another such that the compressible applicator sheet and the bolster material by themselves are held in association with one another, and

a dried, reversible adhesive coating on said bolster material;

wherein said bolster material is held in association with said compressible applicator sheet with at least a portion of said bolster material having an aperture that extends through a thickness of said bolster material, the aperture received around at least a portion of said compressible applicator sheet or at least a portion of said bolster material received through at least a portion of said compressible applicator sheet; and

wherein said bolster material and applicator element are constructed and arranged and are coupled together in such a manner that they can be de-coupled during compression of the medical device against the surgical fastening device with said bolster material in contact with the surface of the surgical fastening device;

wherein said applicator element is sandwiched between said first bolster material portion and said second bolster material portion.

21. The medical device of claim 20 , wherein the dried, reversible adhesive coating on said bolster material is arranged to adhere the bolster material to the surface of the surgical fastening device.

22. The medical device of claim 20 , wherein the bolster material comprises collagen.

23. The medical device of claim 22 , wherein the bolster material comprises an extracellular matrix material.

24. The medical device of claim 23 , wherein the extracellular matrix material comprises submucosa.

25. The medical device of claim 24 , wherein the submucosa is small intestinal submucosa.

26. The medical device of claim 25 , wherein the small intestinal submucosa is porcine.

27. The medical device of claim 20 , wherein the compressible applicator sheet comprises a polymer foam.

28. The medical device of claim 20 , wherein said compressible applicator sheet includes at least one lateral portion adapted for grasping when the compressible applicator sheet is received between said arms.
