Abstract

A method of creating a drug eluting system for hernia repair in a patient is provided. The includes providing an implantable mesh for hernia repair comprised of at least one of polytetrafluoroethylene fibers or polytetrafluoroethylene filaments, wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments is at least one of directionally or non-directionally oriented, positioning a pharmaceutical agent on the implantable mesh, and coating at least a portion of the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments and the pharmaceutical agent with a polymer, wherein the implantable mesh is configured to be positioned in the body of the patient during the repair of the hernia and the pharmaceutical agent elutes from the implantable mesh into the body of the patient at the site of the hernia repair.

First claim

What is claimed is:

1 . A method of creating a drug eluting system for hernia repair in a patient, the method comprising:
providing an implantable mesh for hernia repair comprised of at least one of polytetrafluoroethylene fibers or polytetrafluoroethylene filaments, wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments is at least one of directionally or non-directionally oriented; positioning a pharmaceutical agent on the implantable mesh; and coating at least a portion of the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments and the pharmaceutical agent with a polymer, wherein the implantable mesh is configured to be positioned in the body of the patient during the repair of the hernia, and wherein the pharmaceutical agent elutes from the implantable mesh into the body of the patient at the site of the hernia repair.

2 . The method according to claim 1 , wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments are at least one of interwoven, interlaced, braided, and knitted.

3 . The method according to claim 1 , further comprising placing a primer layer between the mesh and the pharmaceutical agent.

4 . The method according to claim 1 , wherein the pharmaceutical agent is comprised of multiple layers of the same pharmaceutical agent.

5 . The method according to claim 1 , wherein the pharmaceutical agent is comprised of multiple layers of different pharmaceutical agents.

6 . The method according to claim 1 , wherein the pharmaceutical agent is at least one of a drug, therapeutic agent, biological agent, and binary agent.

7 . The method according to claim 1 , wherein the polymer coating is degradable in the body of the patient.

8 . The method according to claim 1 , further comprising transmitting an energy signal to the polymer coating with an energy unit coupled to the external skin of the patient, wherein the polymer coating reacts to the energy signal to increase the release rate of the pharmaceutical agent.

9 . A system for hernia repair in a patient, the system comprising:
a mesh for hernia repair positionable in a body of the patient, the mesh comprised of at least one of polytetrafluoroethylene fibers or polytetrafluoroethylene filaments, wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments is at least one of directionally or non-directionally oriented; a pharmaceutical agent positioned on the mesh; and a polymer positioned on at least a portion of the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments and the pharmaceutical agent.

10 . The system according to claim 9 , wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments are at least one of interwoven, interlaced, braided, and knitted.

11 . The system according to claim 9 , wherein the pharmaceutical agent is bonded to the mesh.

12 . The system according to claim 9 , further comprising a primer layer placed between the mesh and the pharmaceutical agent.

13 . The system according to claim 9 , wherein the pharmaceutical agent is comprised of multiple layers of the same pharmaceutical agent.

14 . The system according to claim 9 , wherein the pharmaceutical agent is comprised of multiple layers of different pharmaceutical agents.

15 . The system according to claim 9 , wherein the pharmaceutical agent is at least one of a drug, therapeutic agent, biological agent, and binary agent.

16 . The system according to claim 9 , wherein the polymer coating is degradable in the body of the patient.

17 . The system according to claim 9 , further comprising an energy unit coupled to the external skin of the patient, the energy unit configured to transmit an energy signal to the polymer coating, wherein the polymer coating reacts to the energy signal to increase the release rate of the pharmaceutical agent.

18 . A system for hernia repair in a patient, the system comprising:
a mesh for hernia repair positionable in a body of the patient, the mesh comprised of at least one of polytetrafluoroethylene fibers or polytetrafluoroethylene filaments, wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments is at least one of directionally or non-directionally oriented; and a pharmaceutical agent positioned on at least a portion of the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments comprising the mesh.

19 . The system according to claim 18 , wherein the at least one of the polytetrafluoroethylene fibers or polytetrafluoroethylene filaments are at least one of interwoven, interlaced, braided, and knitted.

20 . The system according to claim 18 , wherein the pharmaceutical agent is bonded to the mesh.

21 . The system according to claim 18 , further comprising a primer layer placed between the mesh and the pharmaceutical agent.

22 . The system according to claim 18 , wherein the pharmaceutical agent is comprised of multiple layers of the same pharmaceutical agent.

23 . The system according to claim 18 , wherein the pharmaceutical agent is comprised of multiple layers of different pharmaceutical agents.

24 . The system according to claim 18 , wherein the pharmaceutical agent is at least one of a drug, therapeutic agent, biological agent, and binary agent.

25 . The system according to claim 18 , further comprising an energy unit coupled to the external skin of the patient, the energy unit configured to transmit an energy signal to the pharmaceutical agent, wherein the energy signal increases the release rate of the pharmaceutical agent.

26 . A medical device comprising:
a mesh positionable in a body of a patient, the mesh comprised of at least one of polymer fibers or polymer filaments wherein the at least one of the polymer fibers or polymer filaments is at least one of directionally or non-directionally oriented; a pharmaceutical agent positioned on the mesh; and a polymer positioned on at least a portion of the at least one of the polymer fibers or polymer filaments and the pharmaceutical agent.

27 . The medical device according to claim 26 , wherein the at least one of the polymer fibers or polymer filaments are at least one of interwoven, interlaced, braided, and knitted.

28 . The medical device according to claim 26 , further comprising a primer layer placed between the mesh and the pharmaceutical agent.

29 . The medical device according to claim 26 , wherein the pharmaceutical agent is comprised of multiple layers of the same pharmaceutical agent.

30 . The medical device according to claim 26 , wherein the pharmaceutical agent is comprised of multiple layers of different pharmaceutical agents.

31 . The medical device according to claim 26 , wherein the pharmaceutical agent is at least one of a drug, therapeutic agent, biological agent, and binary agent.

32 . The medical device according to claim 26 , wherein the polymer coating is degradable in the body of the patient.
