Abstract

A kit includes a mesh substrate and a polymer that is fixed to the mesh substrate. The polymer includes an active agent that is configured to elute over time. The kit further includes a hemostatic agent. The hemostatic agent is separate from the mesh substrate and the polymer. Systems and methods are disclosed.

Claims (36)

1. A kit comprising:

a substrate comprising collagen;

a tyrosine-derived polyesteramide polymer that that at least partially coats the substrate, the tyrosine-derived polyesteramide polymer including a combination of minocycline and rifampin; and

a hemostatic agent,

wherein the hemostatic agent is tranexamic acid, and

wherein the substrate is disposed in a first package and the hemostatic agent is disposed in a second package that is separate from the first package.

2. The kit recited in claim 1 , wherein the packages are sterile.

3. The kit recited in claim 1 , wherein the substrate consists of collagen.

4. The kit recited in claim 1 , wherein the hemostatic agent is provided in a solution.

5. The kit recited in claim 1 , wherein the hemostatic agent is provided in a suspension.

6. The kit recited in claim 1 , wherein the substrate is a sheet.

7. The kit recited in claim 6 , wherein the sheet has a thickness between about 0.0001 inches and about 0.1 inches.

8. A surgical method comprising:

providing a kit comprising:

a substrate comprising collagen,

a tyrosine-derived polyesteramide polymer that that at least partially coats the substrate, the tyrosine-derived polyesteramide polymer including a combination of minocycline and rifampin, and

a solution comprising tranexamic acid,

wherein the substrate is disposed in a first package and the solution is disposed in a second package that is separate from the first package;

removing the substrate from the first package;

soaking the substrate in the solution; and

implanting the substrate in a patient after the substrate is soaked in the solution.

9. The surgical method recited in claim 8 wherein the substrate consists of collagen prior to being soaked in the solution.

10. The surgical method recited in claim 8 , further comprising coupling an implantable medical device to the substrate after soaking the substrate in the solution and before implanting the substrate in the patient.

11. A kit comprising:

a substrate consisting of collagen, the substrate being a sheet having a thickness between about 0.0001 inches and about 0.1 inches;

a tyrosine-derived polyesteramide polymer that that at least partially coats the substrate, the tyrosine-derived polyesteramide polymer including a combination of minocycline and rifampin; and

tranexamic acid,

wherein the substrate and the tyrosine-derived polyesteramide polymer are disposed in a first sterile package and the tranexamic acid comprises a solution or suspension that is disposed in a second sterile package that is separate from the first package.

12. The kit recited in claim 1 , wherein the substrate is coated with a single layer of the polymer.

13. The kit recited in claim 1 , wherein the substrate is coated with multiple layers of the polymer.

14. The kit recited in claim 1 , wherein the substrate is a mesh.

15. The kit recited in claim 1 , wherein the substrate includes a pocket configured for disposal of an implantable medical device.

16. The kit recited in claim 1 , further comprising an implantable medical device configured for disposal in a pocket of the substrate.

17. The kit recited in claim 1 , further comprising a second hemostatic agent.

18. The kit recited in claim 17 , wherein the second hemostatic agent is disposed in a third package that is separate from the first package and the second package.

19. The kit recited in claim 17 , wherein the second hemostatic agent is selected from the group consisting of epinephrine, chitosan, oxidized regenerated cellulose, thrombin, protamine, norepinephrine, desmopressin, lysine analogs, collagen, gelatin, polysaccharide spheres, mineral zeolite, calcium salt, bovine thrombin, pooled human thrombin, recombinant thrombin, gelatin and thrombin, collagen and thrombin, cyanacrylate, fibrin glue, polyethylene glycol, peptide, and glutaraldehyde.
