Abstract

The present disclosure provides structures and/or gaskets for deposition between adjacent intestinal sections in an anastomosis procedure. The structure possesses at least an inner ring of a first material, and a middle ring of a second material. The first material and the second material include a wound treatment material consisting of at least one of an adhesive, a sealant and/or a medicament. The first material is different from the second material.

Claims

1. A structure for deposition between adjacent intestinal sections in an anastomosis procedure comprising a disk having a first inner portion and a second outer portion, the first inner portion comprising a first material including at least one gap formed along a length thereof to form a discontinuous ring and defining an aperture sized to receive a shaft and the second outer portion comprising a second material different from the first material, the second outer portion extending radially outward from the first inner portion to form a continuous ring around the first inner portion, the first and the second material comprising a wound treatment material consisting of at least one of an adhesive, a sealant, and a medicament.

2. The structure according to claim 1, wherein the structure is impregnated with the wound treatment material.

3. The structure according to claim 1, wherein the structure is a mesh-like material.

4. The structure according to claim 1, wherein the structure is bio-absorbable.

5. The structure according to claim 4, further comprising a third portion extending radially outward from the second portion, wherein the third portion of the structure comprises at least one monomer selected from the group consisting of glycolide, glycolic acid, lactide, lactic acid, p-dioxanone, .epsilon.-caprolactone, trimethylene carbonate, homopolymers thereof, copolymers thereof, and blends thereof.

6. The structure according to claim 5, wherein the third portion of the structure comprises a knitted mesh of polyglycolic acid yarns in combination with a second material selected from the group consisting of glycolide, lactide, trimethylene carbonate, dioxanone, and combinations thereof.

7. The structure according to claim 4, wherein the second portion of the structure comprises at least one monomer selected from the group consisting of glycolide, glycolic acid, lactide, lactic acid, p-dioxanone, .epsilon.-caprolactone, trimethylene carbonate, homopolymers thereof, copolymers thereof, and blends thereof.

8. The structure according to claim 4, wherein the first portion of the structure comprises at least one monomer selected from the group consisting of glycolide, glycolic acid, lactide, lactic acid, p-dioxanone, .epsilon.-caprolactone, trimethylene carbonate, homopolymers thereof, copolymers thereof, and blends thereof.

9. The structure according to claim 8, wherein the first portion of the structure comprises at least one non-absorbable material selected from the group consisting of polyolefins, nylon, and silk.

10. The structure according to claim 8, wherein the first portion of the structure comprises a composite of both non-absorbable and absorbable materials.

11. The structure according to claim 1, wherein the structure is non-absorbable.

12. The structure according to claim 11, further comprising a third portion disposed about an outer perimeter of the second portion, wherein the third portion of the structure comprises at least one non-absorbable material selected from the group consisting of polybuther, polyetherester, polyethylene, polypropylene, nylon, polyethylene terephthalate, polytetrafluoroethylene, polyvinylidene fluoride, stainless steel, and titanium.

13. The structure according to claim 11, wherein the second portion of the structure comprises at least one non-absorbable material selected from the group consisting of polyethylene, polypropylene, nylon, polyethylene terephthalate, polytetrafluoroethylene, polyvinylidene fluoride, stainless steel, and titanium.

14. The structure according to claim 1, further comprising a third portion comprising a composite of both non-absorbable and absorbable materials.

15. The structure according to claim 1, wherein the second portion of the structure comprises a composite of both non-absorbable and absorbable materials.

16. The structure according to claim 1, wherein the wound treatment material comprises at least one adhesive including a hydrogel.

17. The structure according to claim 1, wherein the wound treatment material comprises at least one sealant selected from the group consisting of fibrin sealants, collagen-based sealants, and synthetic polyethylene glycol-based, hydrogel sealants.

18. The structure according to claim 1, wherein the wound treatment material comprises at least one medicament selected from the group consisting of antimicrobials, analgesics, antipyretics, anesthetics, antiepileptics, antihistamines, anti-inflammatories, cardiovascular drugs, diagnostic agents, sympathomimetics, cholinomimetics, antimuscarinics, antispasmodics, hormones, growth factors, muscle relaxants, adrenergic neuron blockers, antineoplastics, immunogenic agents, immunosuppressants, gastrointestinal drugs, diuretics, steroids, lipids, lipopolysaccharides, polysaccharides, enzymes, and combinations thereof.

19. The structure according to claim 1, wherein the structure includes a first layer and a second layer.

20. The structure according to claim 19, wherein the first layer of the structure comprises a first part of a two-part wound treatment material, and the second layer of the structure comprises a second part of the two-part wound treatment material.

21. The structure according to claim 1, wherein the first portion comprises a non-bioabsorbable material and the second portion comprises a bio-absorbable material.
