Description
- This application claims the benefit of U.S. provisional patent application IMPROVED MULTILAYERED POLYMER TUBING WITH BRAIDED LAYER AND METHODS OF MAKING AND USING SAME, Serial No. 60/354,260, filed Feb. 4,2002, hereby incorporated by reference in its entirety, as if set forth below.
- The invention relates to multilayered polymer tubing which includes at least one layer which is braided and methods of manufacturing and using such tubing.
- Tubing is used to carry fluids in a wide variety of applications. Among other things, polymer tubing is used to carry fluids in medical applications and devices, analytical applications and devices, and so forth. Multilayered polymer tubing is also conventional, and has been used in a wide variety of applications. For example, U.S. Pat. Nos. 6,293,312 B1, 6,180197 B1, 5,743,304, 5,641,445, 5,638,871, and 5,630,806 all disclose multilayered polymer tubing, using various polymers for various applications. The foregoing patents are hereby incorporated by reference as if fully set forth herein. In addition, U.S. Pat. Nos. 5,855,977, 5,827,587, 5,756,199, 5,658,670, and 5,656,121 disclose various multilayered polymer composites and methods of making same. The foregoing patents are hereby incorporated by reference as if fully set forth herein.
- A common problem with conventional multilayered tubing is that a unique combination of properties is sometime desirable for a particular application. For example, in high pressure liquid chromatography (HPLC) applications, a combination of high pressures with the chemical solvents used in the chromatographic analysis means that only a limited number of polymers may be appropriate. For higher pressures or applications where structural strength, torsion resistance, lubricity, or other characteristics are required for a given application, there simply may not be a suitable polymer which can be easily used for tubing in the application. Moreover, biocompatibility is often an important and desirable characteristic, especially in many medical applications and devices, as well as in many HPLC and other analytical applications.
- Attached as Appendix 1 hereto are materials describing the various properties and characteristics of several different polymers used in HPLC tubing. Appendix 1 is hereby incorporated by reference as if fully set forth herein. Attached collectively as Appendix 2 hereto are materials describing extruded polymer tubing made from a variety of different polymers and having a variety of useful applications. Appendix 2 is hereby incorporated by reference as if fully set forth herein. The materials of Appendices 1 and 2 describe conventional tubing which is commercially available from Upchurch Scientific of Oak Harbor, Wash.
- In one preferred embodiment of the invention, there is a multilayered tube comprising an inner layer of a tube comprising a first polymer, a second layer of a tube comprising a braided layer comprising a metal or a second polymer, and a third layer of a tube comprising a polymer, which can be either the first, second, or still another third polymer. The braided tube layer provides mechanical strength and rigidity to the multilayered tube without adversely affecting the desired chemical or other properties of the inner and outer layers of the tube.
- In one preferred embodiment ofthe invention, the inner layer comprises polyetheretherketone (PEEK), the braided layer comprises metal (such as any one of the following: 316 stainless steel, 400 series stainless steel, gold, silver, platinum, copper, and similar metals and/or alloys), and the outer layer comprises PEEK. In yet another alternative embodiment of the invention, the inner layer comprises polyethersulfone (PES), the braided layer comprises any one of the materials selected from the following group: aramid fibers (such as those sold under the trademarks KEVLAR and NOMEX, nylon, and the like), graphite fibers, glass fibers, and similar fibrous materials, and the outer layer comprises PES.
- In yet another alternative embodiment, a catheter (or other medical or diagnostic device) comprises a multilayered tube substantially as described herein, where at least one layer is braided. In still another alternative embodiment of the invention, an HPLC system comprises at least one multilayered tube substantially as described herein.
- FIG. 1 is a cross-sectional view of a multilayered tube in accordance with the present invention.
- Referring to FIG. 1, a multilayered tube1 in accordance with the present invention is shown. Tube 1 includes an
inner tube 5, a second,braided tube 10, and a third,outer tube 15. - In one preferred embodiment of the invention, the multilayered tube1 has an
inner tube 5layer 5 made of PEEK. We have found that PEEK offers good solvent resistance and mid pressure range capabilities. Thus, PEEK is useful for a variety of applications with demanding conditions. Disposed around theinner PEEK layer 5 is asecond layer 10 of tubing that is braided. This second braidedlayer 10 of tubing can be made from any one of a number of materials. The braidedlayer 10 can be made of fibers of various materials, including aramids, graphite, glass, and other fibrous materials, or can be made of metal, such as stainless steel, gold, silver, platinum, copper, or other metals. Finally, disposed around the second, braidedtubing layer 10 is athird layer 15 of tubing. In a preferred embodiment of the invention, thisthird layer 15 of tubing is made of PEEK and is extruded over the two inner layers of the multilayered tube 1. - In one particular example of various illustrative embodiments of the invention, we used an
inner layer 5 made of PEEK with an inner diameter of 0.010″ and an outer diameter of 0.020″. Thisinner layer 5 was extruded through conventional means. We then placed a braidedlayer 10 made of 316 stainless steel around theinner layer 5. The thickness of the second, braidedlayer 10 was 0.003″. Finally, we extruded a third,outer layer 15 around the first two layers, with the thirdouter layer 15 made of PEEK with an inner diameter of 0.026″ and an outer diameter of 0.062″. It will be appreciated by those skilled in the art that the dimensions of the various layers of the multilayered tube 1 may be varied depending on the need to accommodate various pressures to which the resulting tube 1 will be exposed, and/or depending on the desired flexibility or rigidity of the resulting tube 1, or other properties or characteristics. - Braiding various materials has been used for many years. The braided
layer 10 can be used to add strength or rigidity as desired to theinner layer 5 of tubing. Thebraided layer 10 of tubing in various illustrative embodiments of our invention allows the resulting multilayered tube 1 to operate at substantially higher pressures and under more difficult conditions than would be the case without the braidedlayer 10. Braiding equipment is commercially available from a number of manufacturers. We have used a Wardwell Rapid 16 Carrier Special Braider that was re-worked by Lloyd and Bouvier of Clinton, Mass. - In another, alternative embodiment ofthe invention, fluoropolymer materials may be used for the inner and outer layers of the multilayered tube1. Such materials offer high solvent resistance and are therefore particularly useful in certain applications where other materials would quickly corrode. In one particular embodiment, an FEP layer having an inner diameter of 0.020″ and an outer diameter of 0.040″ was used as the substrate, or
inner layer 5. Abraid 10 made of 316 stainless steel with a layer thickness of 0.003″ was then made around the firstinner layer 5. Finally, anouter layer 15 made of FEP and having an inner diameter of 0.046″ and an outer diameter of 0.062″ was used as the third,outer layer 15 of the multilayered tube 1. - While the present invention has been shown and described in its preferred embodiment and in certain specific alternative embodiments, those skilled in the art will recognize from the foregoing discussion that various changes, modifications, and variations may be made thereto without departing from the spirit and scope of the invention as set forth in the claims. Hence, the embodiment and specific dimensions, materials and the like are merely illustrative and do not limit the scope ofthe invention or the claims herein.
