Definitions
- This invention relates to a coating for implantable devices, such as an expandable intraluminal prosthesis, one example of which includes a stent. Moreover, the invention is directed to a composition for coating an implantable device.
- Percutaneous transluminal coronary angioplasty is a procedure for treating heart disease.
- a catheter assembly having a balloon portion is introduced percutaneously into the cardiovascular system of a patient via the brachial or femoral artery.
- the catheter assembly is advanced through the coronary vasculature until the balloon portion is positioned across the occlusive lesion.
- the balloon is inflated to a predetermined size to radially pess against the atherosclerotic plaque of the lesion for remodeling of the vessel wall.
- the balloon is then deflated to a smaller profile to allow the catheter to be withdrawn from the patient's vasculature.
- a problem associated with the above procedure includes formation of intimal flaps or torn arterial linings which can collapse and occlude the conduit after the balloon is deflated. Moreover, thrombosis and restenosis of the artery may develop over several months after the procedure, which may require another angioplasty procedure or a surgical by-pass operation. To reduce the partial or total occlusion of the artery by the collapse of arterial lining and to reduce the chance of the development of thrombosis and restenosis, an expandable intraluminal prosthesis, one example of which includes a stent, is implanted in the lumen to maintain the vascular patency.
- Stents are scaffoldings, usually cylindrical or tubular in shape, which function to physically hold open and, if desired, to expand the wall of the passageway.
- stents are capable of being compressed, so that they can be inserted through small cavities via small catheters, and then expanded to a larger diameter once they are at the desired location. Examples in patent literature disclosing stents which have been successfully applied in PTCA procedures include stents illustrated in U.S. Patent No. 4,733,665 issued to Palmaz, U.S. Patent No. 4,800,882 issued to Gianturco, and U.S. Patent No. 4,886,062 issued to Wiktor.
- One commonly applied technique for the local delivery of a drug is through the use of medicated stents.
- One proposed method provided stents which were seeded with endothelial cells (Dichek, D.A. et al. Seeding of Intravascular Stents With Genetically Engineered Endothelial Cells; Circulation 1989; 80: 1347-1353). Briefly, endothelial cells were seeded onto stainless steel stents and grown until the stents were covered. The cells were therefore able to be delivered to the vascular wall where they provided therapeutic proteins.
- Another proposed method of providing a therapeutic substance to the vascular wall included use of a heparin-coated metallic stent, whereby a heparin coating was ionically or covalently bonded to the stent.
- Significant disadvantages associated with the aforementioned methods include significant loss of the therapeutic substance from the body of the stent during delivery and expansion of the stent, and an absolute lack of control of the release rate of the therapeutic substance from the stent.
- stents where immersed in the solution 12 to 15 times or sprayed 20 times.
- the evaporation of the solvent provided a white coating.
- a white coloration is generally indicative of a brittle polymeric coating.
- a brittle polymeric coating is an undesirable characteristic, since portions of the coating typically become detached during stent expansion. Detachment of the coating causes the quantity of the therapeutic substance to fall below a threshold level sufficient for the effective treatment of a patient.
- the polymer it is desirable to provide an improved coating that is susceptible to expanding with a prosthesis without significant detachment from the surface of the prosthesis. It is also desirable for the polymer to be able to strongly adhere to the surface of the prosthesis, thereby preventing loss of the polymeric coating during prosthesis delivery.
- Other desirable features include, but are not limited to, a polymeric coating which allows for a significant control of the release rate of a therapeutic substance, a polymeric coating that can serve as an under-layer for substances which do not easily or effectively bind or adhere to the surface of the prosthesis, a polymeric solution which need not be applied excessively to the surface of the prosthesis to form a coating of a suitable thickness, and a polymeric solution that can be uniformly applied to the surface of the prosthesis.

- the dimethylsulfoxide solution or the combination of the dimethylsulfoxide solution and wetting fluid is removed from the composition which is applied to the surface of the prosthesis.
- One technique for removing the dimethylsulfoxide solution or combination of the dimethylsulfoxide solution and wetting fluid includes allowing the components to evaporate to a substantial elimination, for example, by heating the prosthesis at a predetermined temperature for a predetermined duration of time.
- a layer comprising a polymeric material, without a therapeutic substance can be formed on the therapeutic substance impregnated ethylene vinyl alcohol coating.

- the composition can be applied to both the inner and outer (the tissue contacting) surfaces of the prosthesis.
- Application of the composition can be by any conventional method, such as by spraying the composition onto the prosthesis or immersing the prosthesis in the composition.
- the addition of a wetting fluid leads to a consistent application of the composition which causes the coating to be uniformly deposited on the surface of the prosthesis.
- the prosthesis can be heating by, for example, passing the prosthesis over a hot plate.
- the prosthesis should be exposed to the heat for a short duration of time, typically about 3 to 5 seconds.
- the temperature of the hot plate can be from about 55° C to about 65° C, typically about 60° C. Exposure of the prosthesis to the hot plate prevents the prosthesis from cooling at a rapid rate. Rapid cooling of the prosthesis may adversely affect properties that are generally desirable in a coating, such as elasticity.
- the polymer can be further exposed to heat treatment or cured for a predetermined duration of time, for example for about 6 hours.
- the heat treatment can be conducted generally at the same temperature range as the hot plate, for example from about 55° C to about 65° C, typically about 60° C. The heat treatment prevents formation of air bubbles in the polymeric coating.

- the ethylene vinyl alcohol copolymer can serve as a primer for allowing substances, such as a variety of polymeric materials, to be easily and effectively secured by a prosthesis, more particularly a prosthesis made from a metallic material such as stainless steel.
- the ethylene vinyl alcohol copolymer can serve as an under-layer for a heparin coating for the prosthesis, allowing the heparin coating to be secured more easily and effectively by the prosthesis.
- the heparin coating can be formed on the ethylene vinyl alcohol copolymer coating by any conventional method such as immersion or spraying techniques as is understood by one of ordinary skill in the art.
- the ethylene vinyl alcohol copolymer is a biocompatible coating, i.e., a coating which, in the amounts employed, is non-toxic, non-inflammatory, chemically inert, and substantially non-immunogenetic.
- the coating can have a thickness of about 0.5 microns to about 2.0 microns. The particular thickness of the layer is dependent on the desired use of the primer and the type of procedure for which the prosthesis is employed.
- the coating comprises a polymeric material made from essentially an ethylene vinyl alcohol copolymer having a therapeutic substance or a combination of substances impregnated therein.
- the inclusion of the therapeutic substance or substances in the copolymer matrix allows not only retention of the substance on the prosthesis (e.g., a stent) during delivery and, if applicable, expansion of the prosthesis, but also controlled administration of the substance following implantation.
- the impregnated ethylene vinyl alcohol copolymer can have a thickness of about 0.5 microns to about 1.5 microns. The particular thickness of the copolymer is based on the type of procedure for which prosthesis is employed and the amount of therapeutic substance that is desired to be delivered.
- the amount of therapeutic substance to be included on the prosthesis can be further increased by applying a plurality of coating layers onto the prosthesis.
- the application of each layer should be performed subsequent to the evaporation of the DMSO solvent or DMSO/wetting fluid and the drying of the copolymer of the previous layer.

- a layer or a second coating formed from essentially an ethylene vinyl alcohol copolymer, without a therapeutic substance can be deposited on the therapeutic substance impregnated copolymer coating.
- the substance-free ethylene vinyl alcohol copolymer used as a second coating can comprise a mole percent of ethylene of from about 27% to about 44%. It is understood by one of ordinary skill in the art that ethylene vinyl alcohol copolymer may also be a terpolymer so as to include small amounts of additionally monomers, for example less than about five (5) mole percentage of styrenes, propylene, and other suitable monomers.
- the second coating produces a membrane that reduces the rate of release of the therapeutic substance or substances from the impregnated ethylene vinyl alcohol copolymer, particularly therapeutic substances that are water soluble (e.g., heparin, rapamycin, and dexamethasone). If an ethylene vinyl alcohol copolymer is used as a rate reducing membrane, as a general rule, an increase in the amount of ethylene comonomer content of the second coating decreases the rate that a therapeutic substance can permeate through the second coating.
- the second coating can have a thickness of about 0.25 microns to about 1.5 microns. Typically, the second coating can have a thickness of about 1 micron. It is understood by one of ordinary skill in the art that the thickness of the layer is based on factors such as the type of procedure for which the prosthesis is employed and the rate of release that is desired.
- therapeutic substances can be applied to a prosthesis, e.g., a stent, retained on the stent during delivery and expansion of the stent, and released at a desired control rate and for a predetermined duration of time at the site of implantation.
- the release rate of the substances can be controlled by modifying release parameters such as the amount of ethylene comonomer content of the copolymer and the initial therapeutic substance content in the matrices of the copolymer. Correlations and interrelations between release parameters are well known by one of ordinary skill in the art.
- the rate of release can also be adjusted by the addition of second polymeric layer, with or without a therapeutic substance.
- a stent having the above described medicated coating is useful for a variety of medical procedures, including, by way of example, treatment of obstructions caused by tumors in bile ducts, esophagus, and trachea/bronchi.
- a stent having the above described medicated coating is particularly useful for treating occluded regions of blood vessels caused by formation of intimal flaps or torn arterial linings, thrombosis, and restenosis.
- Stents may be placed in a wide array of blood vessels, both arteries and veins. Representative examples of sites include the iliac, renal, and coronary arteries.
- an angiogram is first performed to determine the appropriate positioning for stent therapy.
- Angiography is typically accomplished by injecting a radiopaque contrasting agent through a catheter inserted into an artery or vein as an x-ray is taken.
- a guidewire is then advanced through the lesion or proposed site of treatment.
- Over the guidewire is passed a delivery catheter which allows a stent in its collapsed configuration to be inserted into the passageway.
- the delivery catheter is inserted either percutaneously or by surgery into the femoral artery, brachial artery, femoral vein, or brachial vein, and advanced into the appropriate blood vessel by steering the catheter through the vascular system under fluoroscopic guidance.
- a stent having the above described coating may then be expanded at the desired area of treatment.
- a post insertion angiogram may also be utilized to confirm appropriate positioning.
