Description

COMBINATION COMPRISING AN AGENT TO PROVIDE A SIGN, AN IMPLANT MATERIAL AND A DRUG Previous applications, and all documents cited therein or during their follow-up ("cited documents of the application") and all documents cited or referred to in the cited documents of the application, and all documents cited or those referenced herein ("documents cited herein"), and all documents cited or those referencing documents cited herein, together with any manufacturer's instructions, descriptions, product specifications, and sheets of product for any products mentioned herein or in any document incorporated herein by reference, are incorporated herein by reference, and may be employed in the practice of the invention. The mention or identification of any document in this application is not an admission that such document is available as the prior art of the present invention. It is noted that in this disclosure and in particular in the claims and / or paragraphs, terms such as, for example, "comprises", "is understood", "comprising" and the like can have the meaning attributed to them in the United States patent law; for example, they may mean "includes", "includes", "including", and the like; and that terms such as, for example, "consisting essentially of" and "consists essentially of" have the meaning attributed to them in the patent law of the United States, for example, admit elements not explicitly mentioned, although they exclude elements that were found in the prior art or that affect a basic or novel feature of the invention. The embodiments of the present invention are set forth herein or are obvious from the detailed description and are encompassed by the same. The detailed description, given by way of example, which is not intended to limit the invention only to the specific embodiments described, can be better understood together with the accompanying drawings. The present invention relates to compositions or combinations of materials for non-degradable and degradable implantable medical devices with respect to the establishment of their characteristics for signal generation and the control of their therapeutic efficacy, as well as to a method for the control of degradation of degradable or partially degradable medical devices, compounds similar to these, based on their generation of the signal, and to a method for monitoring their therapeutic efficacy and / or the release of therapeutically active ingredients from these devices. Ultra-short-term implants, short-term implants such as orthopedic-surgical screws, plates, nails or catheters and needles for injection, as well as long-term implants similar to joint prostheses, artificial heart valves, prostheses vascular, endografts is also the subcutaneous or intramuscular types of implants are made of different types of materials, which are selected according to their specific biochemical and mechanical characteristics. These materials must be suitable for permanent use in the body, without releasing toxic materials and have specific mechanical and biochemical characteristics. The manufacture of these implants with new materials is increasingly allowing the functionality of the implants to be improved. In particular in this regard, systems are used that are partially degradable / soluble or totally (bio-) degradable. A significant problem with these implants is that with the use of new materials, limited physical characteristics are provided, as in the methods for medical imaging, for example during the application, monitoring or control of the correct anatomical position or for other diagnostic or therapeutic reasons, for example, radiopaque or diamagnetic properties, paramagnetic, super paramagnetic or inadequate ferromagnetic. In particular, biodegradable materials such as for example polylactonic acid and its derivatives, collagens, albumin, gelatin, hyaluronic acid, starch, cellulose and the like are typically radiolucent. This also applies for example to polyurethane-like polymers, poly (ethylene vinyl acetate), silicones, acrylic polymers similar to polyacrylic acids, polymethylacrylic acid, polyacrylcyanoacrylate; polyethylene, polypropylene, polyamide, poly (urethane ester), poly (urethane ether), poly (urea ester), polyethelene-like polyethers, polypropylene oxide, pluronics, polytetramethylene glycol; vinyl polymers similar to polyvinylpyrrolidone, polyvinyl alcohol, poly (vini lacetatof talato); Parilenos, based on the material properties are excellently suited for biomedical applications. In particular they are also suitable for non-resorbable medical implants, which consist of polymers or composite materials and mainly are only weakly radiopaque or radiolucent. In contrast to this, there are other material requirements, which are exposed to diagnosis by means of magnetic resonance tomography methods. In contrast to conventional X-ray diagnostics, which are based on the application of ionizing radiation, magnetic resonance tomography (MRI) is not based on ionizing radiation but rather on the production of a magnetic field, raph energy. iof recuence, and gradients of magnetic fields. The signals produced are based predominantly on the measured times of relaxation TI (longitudinal) and T2 (transverse) of excited protons and proton density in tissues. In this way, contrasting materials are typically applied, in order, for example, to influence the proton densities and / or relaxation times produced in tissues or tissue sections, for example, the TI, T2 or proton densities. Another problem is that implantable medical devices are typically modified to improve their properties for imaging. For example, radiopaque filling materials are added to the polymeric materials to improve their visibility. Along with this, typical fillers are BaS04 / bismuth sub carbonate or tungsten-like metals, or other bismuth salts similar to bismuth sub nitrate and bismuth oxide [see U.S. Patent 3,618,614]. Other types of modifications are, for example, the incorporation of halogenated compounds or groups in the polymer matrix. As examples of this, US Patents 4,722,344, 5,177,170 and 5,346,981 are cited herein. The disadvantages of these filling materials are, for example, that fundamental material properties are altered, such as, for example, optical properties, mechanical strength, flexibility, resistance to acid and alkali. Another disadvantage of the disclosed methods is that for example in general a minimum amount of radiopaque fillers or halogenated components must be added to produce any significant radiopaque properties, however the solubility of these fillers in the polymer precursors is limited. Definitely all along there are comparable problems, in the case for example of materials for implant with metal base, intravascular devices, which are in the body temporarily or permanently. As an example of these devices, stents, which typically are made of metals, should be cited. The application of stents is a necessarily invasive method where it is of significant clinical importance that the stent is correctly placed. For this, visualization is customary by means of a method for imaging, for example a method based on X-rays both during and after the application. Based on the alloys used and the low weights of the material, with thin walls or low material resistances, visibility is only weak when it exists in its entirety. Certain radiopaque components that absorb ionizing radiation, also those metal alloys that are biocompatible, can be used according to the prior art, however these typically have a negative impact on the mechanical and (bio) chemical properties. Other methods of the prior art are based on the application of band markers, which are placed by pressure, are stuck or are electrochemically deposited radiopaque materials or metallic coatings. The disadvantages of these solutions are, for example, that the band marker can be displaced or completely removed during application, in addition to damaging the tissue of the internal wall of the container mechanically and traumatizing the surrounding tissue, if they are sharp or are bonded to the tissue. external edges of the implant. In the worst case, band markers cause complications that can make the implant useless. In addition, these bands can lead to rough surfaces that can subsequently lead to the development of thrombosis. Other prior art methods use metal based coatings, which can be produced by C D, PVD or electrochemical methods. However, in order to obtain sufficient radiopaque coatings, the thickness of the coating to produce adhesion on metal substrates is not sufficient to satisfy the mechanical demands placed on these implants, which are insufficient to ensure the safety and efficacy of this implant. On the other hand, electrochemical methods are only adequately limited, since deposition of coatings is typically associated with rough surfaces with worsening of heme-compatibility, or even, depending on the underlying substrate, for brittleness, corrosion or lead to another weakening of the properties of the underlying material of the substrate. These limitations are typically known for alloys with a titanium base, whose mechanical properties deteriorate significantly as a result of the brittleness and therefore the functionality of the implant. Implantations of ion-assisted radiopaque materials have the disadvantage that they are extremely expensive, and have only limited applicability, especially since evaporation is carried out leaving the molten metal, in an amount that exceeds several times the actual amount when placed, the deposition and growth of the coating becomes irregular and difficult to control and for example makes it difficult to perform the implantation of alloys from fusions in a controlled manner due to the different evaporation rates of the elements. Furthermore, implantable medical devices are known which contain the active ingredients in the body for implantation or in the parts of the body for implantation or in the coatings. Through the complete or partial degradation or degradation of the implant body, the implant body parts or the coatings, the active ingredients are released. These implantable medical devices are known to those skilled in the art under the designation "combinatorial devices". It is particularly desired, for non-degradable and degradable materials containing active ingredients, to control the release of the active ingredients in vivo. A review of the prior art shows that these devices combined with the active ingredients do not allow an effective control of the release of the active ingredient from the outside of the body, because the active ingredients used by themselves do not have in their elimination any of the properties for signal generation. Also, if the materials used in which the active ingredients are degradable or soluble incorporated in the presence of physiological fluids, their rate of degradation does not correlate with the release of the active ingredients, even if the matrix materials are visible by the methods for signal detection. An example of this, especially in view of the prior art, is represented by endoprostheses for drug elution, whose release of active ingredients is determined on the basis of expensive in vitro and in vivo studies in very expensive pre-clinical studies. NeverthelessIn these clinical studies, information on the clinical usefulness of the devices can be collected only by means of indirect parameters such as, for example, rates of restenosis, thickening of the vessel wall in question, the ability to penetrate, etc. ex post, months after implantation. For the actual limitations with respect to the control of the release of the active ingredient, reference is made here to Schwart et al., Circulation. 2002; 106: 1867. Therefore, there is a need for medical implants that are detectable for diagnostic and therapeutic purposes during or after their application by methods of imaging, which are based on ionizing radiation, radiofrequency radiation, fluorescence or luminescence, or methods with base in sound and resemblance. In particular there is a need for visible implants in methods for the production of images that are totally or partially biodegradable or bioerodible, and the rate of degradation in correspondence with methods for non-invasive measurement and detection, for example, the method for production of images, is controllable with respect to residence time and allows a correlation between the effectiveness of the implant and the therapeutic result with respect to the acquisition of implantation / tissue limits and new tissue growth.
BRIEF DESCRIPTION OF THE INVENTION Therefore, the present invention in one aspect provides implants that will be visible by the methods for producing images, which can preferably be made visible at the same time as much as possible for the methods for producing images. based on different physical principles. The embodiments of the present invention allow control of the correct anatomical placement of an implantable medical device in situ during the application, conventionally by means of radiographic methods, but also for the monitoring and supervision of therapeutic efficacy, with the use of methods for base detection without causing stress or non-invasive for example based on MRI. In addition, the invention provides the assemblies of implantable medical devices, which contain therapeutically active ingredients and release them in a controllable manner, for example, since for the degradable or partially degradable components the degree of degradation can be correlated with the degree of release of the Therapeutically active ingredients, or, as for the implantable devices that release the non-degradable active ingredient, the active ingredient is coupled to a signal producing agent and the depletion of signals in the device or parts of the device indicates the degree of release of the active ingredients.
Also, in additional aspects, the present invention allows to control the release of active ingredients from an implant, to detect locally the enrichment of the active ingredients, which are released from an implantable medical device, in the specific compartments of the organism, organs, tissues or cells, especially in specific cell types. Additionally, the present invention provides methods for implantable medical devices whose therapeutic efficacy can be controlled with or without the release of the active ingredient by enriching signal-producing agents in the organism, organ, tissue or cell compartments, especially in specific cell types, where these already have the inherent properties for signal generation, or are only transformed in vivo in the agents for signal generation by biological mechanisms. This can be preferred in a special way, if for example an implantable medical device is applied as a tissue substitute in malignant tissue, and it changes after metastasis or tumor removal, and satisfies the purpose, the release of the agents for generation of signal, recurrence in the immediate or communicable surroundings of the implant by means of selective enrichment, around for example through target groups, to make them visible in this altered cell or tissue types. Also, the present invention provides methods that make it possible not to deteriorate the composition of the implant material through the mixing of detectable substances which thereby limit or even destroy the functionality.

In addition, the cells, cell cultures, organized cell cultures, tissues, organs or desired species and non-human organisms may contain one or a plurality of vectors as described above. Agents for signal generation preferably are produced in vivo from the group of proteins and are available as described above. These agents preferably directly or indirectly produce signals, while the cells produce (directly) a signal producing protein through transfection or produce a protein that induces (indirectly) the production of a signal producing protein. Preferably, these signal generation agents can be detected in methods such as for example MRI while the relaxation times TI, T2 or both are altered and lead to effects for signal production that can be sufficiently processed for imaging . These proteins are preferably protein complexes, especially metalloprotein complexes. The proteins for direct signal production are preferably these metalloprotein complexes that are formed in the cells. The agents for indirect signal production are these proteins or nucleic acids, for example, that regulate the homeostasis of iron metabolism, the expression of endogenous genes for the production of agents for signal generation, and / or the activity of endogenous proteins with properties for direct signal generation, for example the Iron Regulatory Protein (IRP), Transferrin receptor (for Absorption of Fe), eri troide-5-aminobevulinate synthase (for the utilization of Fe, H-Ferritin and L-Ferritin in order to accumulate Fe). In specific embodiments it may be preferred to combine both types of agents for signal generation, which is direct and indirect, with each other, for example an agent for indirect signal generation, which regulates homeostasis with iron and a direct agent, which represents a protein of union with metals. In these embodiments, where preferably the metal-binding polypeptides are selected as indirect agents, it is advantageous if the polypeptide binds to one or a plurality of metals that possess the properties for signal generation. In particular, metals with odd electrons are preferred in the Dorf orbitals, such as, for example, Fe, Co, Mn, Ni, Gd, etc., where in particular Fe is available in high physiological concentrations in organisms. It is also preferred if these agents form metal-rich aggregates, for example crystalline aggregates, whose diameters are greater than 10 picometers, preferably greater than 100 picometers, 1 nm, 10 nm or especially greater than 100 nm.

Typical polypeptides or metal-binding proteins are lac toferrin, ferritin, or other layered dimethalocarboxy proteins or the like, or the so-called metal collector with ideroforic groups, similar to for example hemoglobin. A possible method for the preparation of these agents for signal generation, their selection the possible direct or indirect agents that can be produced in vivo and are suitable as signal generating agents are disclosed in WO 03/075747 and incorporated in the same according to the invention. Another group of agents for signal generation can be agents for producing photophysical signals consisting of peptide dye conjugates. These dye peptide conjugates are preferred which provide a broad spectrum of maximum absorption, for example polymethine dyes, in particular cyanine, merocyanine, oxonol and schiaryl dyes. From the class of polymethine dyes cyanine dyes, for example, indocarbo-indodicarbo- and indotricarbocyanines based on an indole structure are especially preferred. These dyes may be preferred in specific embodiments, which are substituted with suitable binding agents and may be functional groups with other groups as desired. Accordingly, see also DE 19917713, which is explicitly incorporated by reference. In accordance with the invention, the agents for signal generation can be functional groups as desired. It should be understood that functionalization is preferred by so-called "white" groups, as functional chemical compounds that bind to the agent for signal generation or its specifically available form (encapsulation, micelles, microspheres, vectors, etc.). ) towards a specific functional location, or towards a specific cell type, type of tissue or other target structures desired. The target groups preferably allow the accumulation of agents for signal production in specific target structures. Therefore, target groups can be selected from these substances, which are primarily suitable for providing useful enrichment of the signal generation agents in their specifically available form via physical, chemical or biological routes or combinations thereof. The useful white groups that will be selected can therefore be antibodies, cell receptor ligands, hormones, lipids, sugars, dextran, alcohols, bile acids, fatty acids, amino acids, peptides and nucleic acids, which can be chemically or physically bound to the agents for signal generation, in order to bind the agents for signal generation in / on a specifically desired structure. In a first embodiment, target groups are selected, which enrich the agents for signal generation in / on a tissue type or on cell surfaces. It is not necessary for the function, that the agent for signal generation is absorbed in the cytoplasm of the cells. As white groups, peptides are preferred, for example chemotactic peptides are used to cause inflammation reactions in visible tissues by means of signal generating agents.; in this regard also see WO 97/14443, which is explicitly incorporated by reference. Antibodies are also preferred, including antibody fragments, Fab, Fab2, single chain antibodies (eg Fv), chimeric antibodies, and the like, as is known from the prior art, in addition to the antibody-like substances, example the so-called anticalines, where it is unimportant if the antibodies are modified after the preparation, recombinants are produced or if they are human or non-human antibodies. It is preferred to select from humanized or human antibodies, examples of humanized forms of non-human antibodies are chimeric immunoglobulins, immunoglobulin chains or fragments (similar to Fv, Fab, Fab ', F (ab ") 2 or other sub-sequences of antigen-binding antibodies, which partially contain non-human antibody sequences, humanized antibodies contain for example human immunoglobulins (receptor antibodies or containers), in which the groups of a CDR (Complementary Determinant Region) of the receptor are replaced by groups of a CDR of a non-human antibody (strenuous or donor), wherein the strenuous species eg mouse, rabbit or other has a specificity, affinity, and ability to bind the target antigens. The groups of the Fv structure of human inmunglobulins are replaced by the corresponding non-human groups. Furthermore, they can contain groups that do not appear in the CDR or the sequence of the Fv structure of the strenuous or the container. Humanized antibodies essentially comprise at least one or preferably two variable domains, in which all or the substantial components of the CDR components of the CDR regions or the sequences of the Fv structure correspond to those of the non-human immunoglobulin , and all or the substantial components of the FR regions correspond to a human consensus sequence. According to the invention, the target groups of this embodiment can also be hetero-conjugated antibodies. The preferred function of the selected antibodies or peptides is that of markers or molecules of cell surfaces, in particular of cancer cells, where many surface structures are known, such as for example HER2, VEGF, CA 15-3, CA 549, CA 27.29, CA 19, CA 50, CA242, MCA, CA 125, DE-PAN-2, etc., and the like.

In a second embodiment, the target groups may be selected from a group of functional compounds that make possible the internalization or incorporation of the agents for signal generation in cells, especially in the cytoplasm or in specific cellular compartments or organelles, such as for example a cell nucleus. For example, it is preferred that the target group contains all or portions of HIV-I tat proteins, analogs and similar proteins derived or functionally similar, and thus allow a particularly rapid absorption of substances into cells. As an example, reference is made to Fawell et al., PNAS USA 91: 664 (1994); Frankel et al., Cell 55: 1189, (1988); Savion et al., J. Biol. Chem. 256: 1149 (1981); Derossi et al., J. Biol. Chem. 269: 10444 (1994); and Baldin et al., EMBO J. 9: 1511 (1990), which are incorporated herein explicitly in accordance with the invention. The target groups can also be selected from the so-called Nuclear Localization Signal (NLS), where it is understood that under the short positively charged (basic) domains they bind to the specifically targeted structures of the cell nuclei. Many NLS and their amino acid sequences are known including a single basic NLS similar to the SV40 long T antigen (monkey virus) (pro Lys Lys Arg Lys Val), Kalderon (1984), et al., Cell, 39: 499-509), the nuclear localization signal of the teinoic acid [beta] -receptor (ARRRRP); NFKB p50 (EEVQRKRQKL; Ghosh et al., Cell 62: 1019 (1990); NFKB p65 (EEKRKRTYE; Nolan et al., Cell 64: 961 (1991), as well as others (see for example Boulikas, J. Cell.

Cell Biol., 107: 641-849, 1988. All of these are incorporated herein. As reference in accordance with the invention, many localization studies have shown that NLS, which are synthetic peptides that normally do not target the cell nucleus and do not bind to the reporter proteins, lead to an enrichment of these proteins and peptides in cell nuclei In this regard the example references are Dingwall, and Laskey, Ann, Rev. Cell Biol., 2: 367-390, 1986, Bonnerot, et al., Proc. Nati, Acad. Sci. USA, 84: 6795-6799, 1987; Galileo, et al., Proc. Nati Acad. Sci. USA, 87: 458-462, 1990.

The agents for generating bi, tri and multifunctional signal can be presented correspondingly with the prior art totally or partially as covalent or non-covalent unit macromolecules, as micelles or microspheres, encapsulated in liposomes or encapsulated in polymers or covalently bound in polymers. For covalent bonds, substituents in the form of functional groups according to the prior art are coupled to the individual components, they will be selected, for example, from amino, carboxyl, oxo or thiol groups. These groups can be linked together directly or through a linker. The binders of the prior art have been described many times, for example, the homo or heterofune binders as described in Pierce Chemical Company catalog, technical section on cross-linkers, pages 155-200, (1994), and incorporated herein by reference. the present as a reference.

In exemplary embodiments of the devices and methods of the present invention, an implantable medical device, eg, a metal stent or a pacemaker electrode or an artificial heart valve, is coated with a porous coating, for example, with a coating of pyrolytic carbon as described in DE 202004009060U. The coating is subsequently loaded with at least one agent for signal generation as described above, and simultaneously or subsequently with at least one therapeutic agent as described above, selected according to the intended use of the device, wherein the order of the load with the different agents can be selected as deemed appropriate. The loading can be done by spraying, impregnation with solutions or in any other suitable way. If necessary, adjuvants or overdrafts can also be applied to control the release rates of the agents. The average release rates of the agent for signal generation and the therapeutic agent from the thus produced implantable device can be determined by the common use of in-vitro tests in balanced salt solution or any other suitable means. From the concentration measurements, optionally combined with methods for non-invasive physical detection for the signal generation agents, a correlation coefficient can be determined for the amount of the therapeutic agent released by the amount of signal strength obtained from the agent for signal generation, which allows an indirect determination of the amount of the therapeutic agent released in relation to the signal intensity obtained from the detection of the agent for signal generation. With this method, the supervision of the quantity and regional distribution of the liberated therapeutic agent is possible precisely through simple non-invasive physical detection methods.

The solids content of the polymer amounted to 0.75% by weight, the solids content of Aerosil 0.25% by weight, the solids content of the solvent to 99% by weight. The precursor solution was sprayed on the substrate as a polymeric film, tempered by the application of hot air at 350 ° C in ambient air and subsequently the crude weight of the polymeric film was determined, where the coating had a weight in the area surface of approximately 2.53 g / m2. The sample was subsequently examined in a Nikon fluorescence microscope for its inherent fluorescence. The crude coating had no fluorescence. Subsequently, the sample was thermally treated according to DE 202004009060U in a commercial tube reactor. The thermal treatment was carried out in accordance with nitrogen atmosphere with a heating and cooling ramp of 1.3 K / min with a holding temperature of 300 ° C and a maintenance time period of 30 minutes.
The sample was then treated in an ultrasonic bath in 10 ml of a 50% ethanol solution at 30 ° C for 20 minutes, washed and dried in a commercial convection oven set at 90 ° C. The gravimetric analysis indicated a shrinkage after the heat treatment of about 29% and a weight in the surface area of the amorphous carbon / Si composite layer of 1.81 g / m2.

For modifying the emission spectrum by fluorescence in the red region, the composition of the precursor was modified. As the precursor polymer, a phenoxy resin, Beckopox EP 401 from UCB Company, was used and combined with a dispersion of Aerosil R972 commercially available from Degussa in methyl ethyl ketone. Additionally, a degradation agent, isophorone diisocyanate, was introduced from Sigma Aldrich Company. The solids content of the polymer amounted to 0.55% by weight, the solids content of Aerosil to 0.25% by weight, the solids content of the agent for degradation to 0.2% by weight, the solid portion of solvent to 99% by weight. The precursor solution was sprayed on the substrate as a polymer film, tempered by the application of hot air at 350 ° C in ambient air and subsequently the raw weight of the polymer film was determined, where the coating had a weight in the surface area of approximately 2.20 g / m2. The sample was subsequently examined in a Nikon fluorescence microscope for its inherent fluorescence. The crude coating had no fluorescence. Subsequently, the sample was thermally treated according to DE 202004009060U in a commercial tube reactor. The heat treatment was carried out under a nitrogen atmosphere with a heating and cooling ramp of 1.3 K / min with a holding temperature of 300 ° C and a maintenance period of 30 minutes. Subsequently, the sample was treated in an ultrasonic bath in 10 ml of a 50% ethanol solution at 30 ° C for 20 minutes, washed and dried in a commercial convection oven set at 90 ° C. The gravimetric analysis indicated a contraction after the heat treatment of approximately 23% and a weight in the surface area of the composite layer of carbon / Si amorphous similar to glass of 1.69 g / m2. The scanning electron microscope investigation showed a porous layer with average pore diameters of approximately 100 nm. Further investigation in a fluorescence microscope showed intensive fluorescence of the coated stent in the green and blue region as well as strong fluorescence in the red region.
Example 3 The coronary stent produced in Example 1 and Example 2 were subsequently exchanged with an active agent. Paclitaxel obtained from Sigma Aldrich was used as a model substance. A solution of Paclitaxel having a concentration of 43 g / 1 was prepared in ethanol. Before and after being changed by immersion in 5 ml of ethanolic solution with paclitaxel, the samples were subjected to a gravimetric analysis .. The loading was carried out by immersion for 10 minutes in the solution of the active agent. The total load was determined from the mass increase. The sample of Example 1 had a load of 0.766 g / m2, the sample of the Example had a load of 0.727 g / m2. After drying in air for 60 minutes, another investigation was carried out by fluorescence microscopy, which showed the same fluorescence characteristics of the non-charged porous coatings (strong fluorescence of blue and green, the sample of Example 1 weak red fluorescence, the sample of Example 2 strong red fluorescence).
EXAMPLE 4 Three non-fluorescent, non-fluorescent coronary stents, commercially available from Fortimedix Company (KAON Stent), the Netherlands, 18.5 mm long, made of 316L stainless steel were coated with a carbon-carbon composite material coating in accordance with the DE 202004009060U. As the precursor polymer, a phenoxy resin, Beckopox EP 401 from UCB Company was used and from the same a dispersion was prepared in methyl ethyl ketone with commercially available carbon black, Printex alpha from Degussa and a mixture of fullerene C60 and C70 from FCC Company sold as Nanom-Mix The solids content of the polymer amounted to 0.5% by weight, the solids content of carbon black to 0.3% by weight, the solids content of the fullerene mixture to 0.2% by weight, that of the solvent to 99% by weight. The precursor solution was sprayed on the substrate as a polymeric film, tempered by the application of hot air at 350 ° C in ambient air and subsequently the crude weight of the polymeric film was determined, where the coating had a weight in the area surface of approximately 2.5 g / m2. The sample was subsequently examined in a Nikon fluorescence microscope for its inherent fluorescence. The crude coating had no fluorescence. Subsequently, the sample was thermally treated according to DE 202004009060U in a commercial tube reactor. The heat treatment was carried out under a nitrogen atmosphere with a heating and cooling ramp of 1.3 K / min with a holding temperature of 300 ° C and a maintenance period of 30 minutes. Subsequently, the sample was treated in an ultrasonic bath in 10 ml of a 50% ethanol solution at 30 ° C for 20 minutes, washed and dried in a commercial convection oven set at 90 ° C. The gravimetric analysis indicated a contraction after the heat treatment of approximately 30% and a weight in the surface area of the coating composed of an amorphous carbon / pyrolytic carbon similar to glass of 1.75 g / m2. The scanning electron microscope revealed an average porosity of 1 μp ?. Investigation with a fluorescence microscope did not indicate fluorescence of the coating. For the loading of the active agent, first a 1 mM solution of Calcein-AM in DMSO from obitec Company, was diluted to 1: 1000 in acetone and 0.5 mg of the calcein solution was mixed together with 20 mg of poly (DL) - lactide coglycolide) and 2 mg of Paclitaxel in 3 ml of acetone. The resulting solution was added with a constant flow rate of 10 ml / min to a 0.1% solution of Poloxamer 188 (pluronic F68) in 0.05 M PBS buffer while stirring at 400 rpm, and the colloidal suspension was further stirred during 3 h under light vacuum for the evaporation of the solvents and then dried completely for 14 h under total vacuum. The nanoparticles obtained with encapsulated Paclitaxel and in-vivo fluorescence marker were subsequently resuspended in ethanol and by determining the solids content, the concentration of the solution containing particles was obtained. The three posteriorly coated coronary stents were loaded with the particles by immersion and the loaded weight was determined gravimetrically. The average load of coronary stents dried by convection oven amounted to 0.5 g / m2 + 0.05. Subsequently, the stent expanded placed in 6-well plates and incubated with approximately 105 cells / ml, cultured COS-7 cells subcultured three times (37.5 ° C, 5% C02) in DMEM medium in a volume of culture 5 mi. Immediately after the expansion, after 1, 3, 6, 12, 24, 36 as well as also 2, 3, 4, 5, 7, 9, 12, 15, 21 and 30 days in each case the volumes of culture, the amounts released were determined by means of HPLC, and in each case the medium was replaced. In addition, the samples were investigated in the fluorescence microscope and the adherent cells were investigated for fluorescence in the green region. Using the software Lucia de Nikon Company in each case, an area of 0.5 μp? 2 was determined by densitometric measurement of the average color intensity of the fluorescence intensity. The maximum densitometric was observed after 30 days and the intensity of the fluorescence values was determined to be correlated with the release of calcein-AM in percentage against time. The graph of Figure 1 collects the measured values and showing the correlation between the release of the dry particles adsorbed Paclitaxel nanopart encapsulated from the stent and the in vivo activity of the fluorescent dye Calcein-AM. After a period of 35 days, the samples were transferred into new culture vessels and incubated with freshly prepared cell suspension. Paclitaxel could not be identified in the medium nor was there any fluorescence dye from the cell culture. Thus, having described in detail the preferred embodiments of the present invention, it should be understood that the invention defined by the claims below is not limited to particular details set forth in the above description as are possible many apparent variations thereof without depart from the spirit or scope of the present invention.
