Abstract

An apparatus for use with a surgical stapler to provide a reinforced surgical staple line. The apparatus includes an applicator that carries a first and second bioimplantable material connected by a hinge. An applicator clip may be provided to releasably secure the first and second bioimplantable material onto the applicator.

Claims

1. An apparatus for use with a surgical stapler to provide a reinforced surgical staple line comprising:

an applicator strip having a first end and a second end, and further having a first face and a second face;

a first bioimplantable material having a first face adapted to attach to a first jaw of a surgical stapler and a second face in juxtaposed relation with the first face of the applicator strip;

a second bioimplantable material having a first face adapted to attach to a second jaw of a surgical stapler and a second face in juxtaposed relation with the second face of the applicator strip; and

a hinge connecting the first bioimplantable material to the second bioimplantable material,

wherein the first face of the applicator strip is in contact with a substantial portion of the of the second face of the first bloimplantable material and the second face of the applicator strip is in contact with a substantial portion of the second face of the second bioimplantable material,

wherein the second end of the applicator strip is disposed adjacent to the hinges, and

wherein a biocompatible adhesive is disposed on the first face of the first bioimplantable material and the first face of the second bioimplantable material, the adhesive being adapted to removably secure the first face of the first bioimplantable material to the first jaw of the surgical stapler and the first face of the second bioimplantable material to the second jaw of the surgical stapler.

2. The apparatus of claim 1 wherein the first bioimplantable material and the second bioimplantable material comprise a length of a single material.

3. The apparatus of claim 1 wherein the first bioimplantable material, the second bioimplantable material, and the hinge all comprise the same material.

4. The apparatus of claim 1 wherein the first bioimplantable material, the second bioimplantable material, and the hinge are formed from a single length of material.

5. The apparatus of claim 1 wherein the first bioimplantable material has a first end and a second end, and the second bioimplantable material has a first end and a second end, such that the second end of the first bioimplantable material and second end of the second bioimplantable material are hingedly connected together.

6. The apparatus of claim 5 wherein the first end of the first bioimplantable material and the first end of the second bioimplantable material are each disposed near the first end of the applicator strip.

7. The apparatus of claim 6 further comprising an applicator clip, wherein the clip contacts the first face of the first bioimplantable material such that the second face of the first bioimplantable material contacts the first face of the applicator strip, and wherein the clip contacts the first face of the second bloimplantable material such that the second face of the second bloimplantable material contacts the second face of the applicator strip.

8. The apparatus of claim 1 wherein the applicator strip has a longitudinal length that is greater than that of the first and second jaws of the surgical stapler such that a portion of the applicator strip extends beyond an end of the first and second jaws.

9. The apparatus of claim 7 wherein the applicator clip is engaged with the first end of the first bioimplantable material and the first end of the second bioimplantable material.

10. The apparatus of claim 7 wherein the applicator clip is circumferentially disposed about the first end of the first bioimplantable material, the first end of the second bioimplantable material, and the first end of the applicator strip.

11. The apparatus of claim 1 wherein the first bioimplantable material, the second bioimplantable material, and the applicator strip each comprise an approximately equal transverse width.

12. The apparatus of claim 1 wherein the applicator strip has a transverse width that is approximately equal to that of the first and second jaws of the surgical stapler such that a side portion of the applicator strip does not extend beyond a side portion of the first and second jaws.

13. The apparatus of claim 1 wherein a major portion of the first face of the applicator strip is in contact with the second face of the first bioimplantable material and a major portion of the second face of the applicator strip is in contact with the second face of the second bioimplantable material.

14. The apparatus of claim 1 further comprising a removable applicator clip for engaging the second face of the first bioimplantable with the first face of the applicator strip and the second face of the second bioimplantable material with the second face of the applicator strip, the applicator clip being spaced apart from the hinge.

15. The apparatus of claim 14 wherein the applicator clip is circumferentially disposed about the applicator strip.

16. The apparatus of claim 14 engages the first face of the first bioimplantable and the first face of the second bioimplantable material.

17. A kit for applying a biocompatible material to the working surface of a jaw of a surgical fastener to a produce reinforced surgical fastener line, comprising:

an applicator strip having a longitudinal length and a transverse width, and further having a first face and a second face;

a first bioimplantable material having a longitudinal length and a transverse width, and further having a first face adapted to attach to a first jaw of a surgical stapler and a second face in juxtaposed relation with the first face of the applicator strip;

a second bioimplantable material having a longitudinal length and a transverse width, and further having a first face adapted to attach to a second jaw of a surgical stapler and a second face in juxtaposed relation with the second face of the applicator strip;

a hinge connecting the first bioimplantable material to the second bioimplantable material;

a biocompatible adhesive that removably secures the first and second biocompatible material to the working surface of the jaw; and

an applicator clip,

wherein the transverse width of the applicator strip, the first bioimplantable material, and the second bioimplantable material are approximately equal, and

wherein the applicator clip contacts the first face of the first bioimplantable material such that the second face of the first bioimplantable material contacts the first face of the applicator strip, and wherein the applicator clip contacts first face of the second bioimplantable material such that the second face of the second bioimplantable material contacts the second face of the applicator strip, and further wherein the applicator clip contacts the first bioimplantable material and the second bioimplantable material at a location spaced apart from the hinge.

18. The kit of claim 17 wherein the longitudinal length of the applicator strip is greater than that of the first and second jaws of the surgical stapler such that a portion of the applicator strip extends beyond an end of the first and second jaws.

19. The kit of claim 17 wherein the transverse width of the applicator strip is approximately equal to that of the first and second jaws of the surgical stapler such that a side portion of the applicator strip does not extend beyond a side portion of the first and second jaws.

20. The kit of claim 17 wherein a major portion of the first face of the applicator strip is in contact with the second face of the first bioimplantable material and a major portion of the second face of the applicator strip is in contact with the second face of the second bioimplantable material.
