Definitions
- thrombotic and inflammatory response Upon pressure expansion of an intracoronary balloon catheter during angioplasty, smooth muscle cells within the vessel wall become injured, initiating a thrombotic and inflammatory response.
- Cell derived growth factors such as platelet derived growth factor, basic fibroblast growth factor, epidermal growth factor, thrombin, etc., released from platelets, invading macrophages and/or leukocytes, or directly from the smooth muscle cells provoke a proliferative and migratory response in medial smooth muscle cells. These cells undergo a change from the contractile phenotype to a synthetic phenotype characterized by only a few contractile filament bundles, extensive rough endoplasmic reticulum, Golgi and free ribosomes. Proliferation/migration usually begins within one to two days post-injury and peaks several days thereafter (Campbell and Campbell, 1987; Clowes and Schwartz, 1985).
- inflammatory cells adhere to the site of vascular injury. Within three to seven days post-injury, inflammatory cells have migrated to the deeper layers of the vessel wall. In animal models employing either balloon injury or stent implantation, inflammatory cells may persist at the site of vascular injury for at least thirty days (Tanaka et al., 1993; Edelman et al., 1998). Inflammatory cells therefore are present and may contribute to both the acute and chronic phases of restenosis.
- anti-proliferative (or anti-restenosis) concentrations may exceed the known toxic concentrations of these agents so that levels sufficient to produce smooth muscle inhibition may not be reached (Mak and Topol, 1997; Lang et al., 1991 ; Popma et al., 1991).
- a stent 100 in accordance with the present invention may be embodied in a shape-memory material, including, for example, an appropriate alloy of nickel and titanium or stainless steel.
- the stent 100 may be compressed so as to occupy a space sufficiently small as to permit its insertion in a blood vessel or other tissue by insertion means, wherein the insertion means include a suitable catheter, or flexible rod.
- the stent 100 On emerging from the catheter, the stent 100 may be configured to expand into the desired configuration where the expansion is automatic or triggered by a change in pressure, temperature or electrical stimulation.
- a lubricant or mold release agent may be utilized.
- the lubricant or mold release agent may comprise any suitable biocompatible lubricious coating.
- An exemplary lubricious coating may comprise silicone.
- a solution of the silicone base coating may be introduced onto the balloon surface, onto the polymeric matrix, and/or onto the inner surface of the sheath of a self-expanding stent delivery apparatus and allowed to air cure.
- the silicone based coating may be incorporated into the polymeric matrix.
- the balloon 200 comprises a lubricious coating 202.
- the lubricious coating 202 functions to minimize or substantially eliminate the adhesion between the balloon 200 and the coating on the medical device.
- the lubricious coating 202 would minimize or substantially eliminate the adhesion between the balloon 200 and the heparin or rapamycin coating.
- the lubricious coating 202 may be attached to and maintained on the balloon 200 in any number of ways including but not limited to dipping, spraying, brushing or spin coating of the coating material from a solution or suspension followed by curing or solvent removal step as needed.
- polyethylene glycol waxes and inorganic materials such as talc, kaolin, mica, and silica may be used to prepare these coatings.
- Vapor deposition polymerization e.g. parylene-C deposition, or RF-plasma polymerization of perflouroalkenes can also be used to prepare these lubricious coatings.
- the lubricious coating may be affixed to the inner surface of the restraining sheath.
- Figure 8 illustrates a self- expanding stent 400 within the lumen of a delivery apparatus sheath 402.
- a lubricious coating 404 is affixed to the inner surfaces of the sheath 402. Accordingly, upon deployment of the stent 400, the lubricious coating 404 preferably minimizes or substantially eliminates the adhesion between the sheath 402 and the drug, agent or compound coated stent 400.
- physical and/or chemical cross-linking methods may be applied to improve the bond strength between the polymeric coating containing the drugs, agents or compounds and the surface of the medical device or between the polymeric coating containing the drugs, agents or compounds and a primer.
- primers applied by either traditional coating methods such as dip, spray or spin coating, or by RF-plasma polymerization may also be used to improve bond strength.
- the bond strength can be improved by first depositing a primer layer 500 such as vapor polymerized parylene-C on the device surface, and then placing a second layer 502 which comprises a polymer that is similar in chemical composition to the one or more of the polymers that make up the drug-containing matrix 504, e.g., polyethylene-co-vinyl acetate or polybutyl methacrylate but has been modified to contain cross-linking moieties.
- This secondary layer 502 is then cross-linked to the primer after exposure to ultraviolet light. It should be noted that anyone familiar with the art would recognize that a similar outcome could be achieved using cross-linking agents that are activated by heat with or without the presence of an activating agent.
- a related problem occurs in medical devices such as stents.
- some struts come into contact with each other and when the stent is expanded, the motion causes the polymeric coating comprising the drugs, agents or compounds to stick and stretch. This action may potentially cause the coating to separate from the stent in certain areas.
- the predominant mechanism of the coating self-adhesion is believed to be due to mechanical forces.
- the polymer comes in contact with itself, its chains can tangle causing the mechanical bond, similar to Velcro®.
- Certain polymers do not bond with each other, for example, fluoropolymers. For other polymers, however, powders may be utilized.
