Description: BIOMATERIALS MODIFIED WITH SUPEROXIDE DISMUTASE MIMICS CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority from provisional application number 60/136,298 filed May 27, 1999, which is hereby incorporated by reference in its entirety for all purposes. BACKGROUND OF THE INVENTION The present invention relates to biomaterials modified with non-proteinaceous catalysts for the dismutation of superoxide, and processes for making such materials. This modification may be by covalent conjugation, copolymerization, or admixture of the non- proteinaceous catalysts with the biomaterial . The resulting modified biomaterials exhibit a marked decrease in inflammatory response and subsequent degradation when placed in contact with vertebrate biological systems. "Biomaterial" is a term given to a wide variety of materials which are generally considered appropriate for use in biological systems, including metals, polymers, biopolymers, and ceramics. Also included in the term are composites of such materials, such as the polymer- hydroxyapatite composite disclosed in U.S. Pat. No. 5,626,863. Biomaterials are used in a variety of medical and scientific applications where a man-made implement comes into contact with living tissue. Heart valves, stents, replacement joints, screws, pacemaker leads, blood vessel grafts, sutures and other implanted devices constitute one major use of biomaterials. Machines which handle bodily fluids for return to the patient, such as heart/lung and hemodialysis machines, are another significant use for biomaterials. Common metal alloy biomaterials used for implants include titanium alloys, cobalt-chromium-molybdenum alloys, cobalt-chromium-tungsten-nickel alloys and nonmagnetic stainless steels (300 series stainless steel) . See U.S. Pat. No. 4,775,426. Titanium alloys are frequently used for implants because they have excellent corrosion resistance. However, they have inferior wear characteristics when compared with either cobalt- chromium-molybdenum alloys or 300 series stainless steel. Cobalt-chromium-molybdenum alloys have about the same tensile strength as the titanium alloys, but are generally less corrosion resistant. They also have the further disadvantage of being difficult to work. In contrast, the 300 series stainless steels were developed to provide high-strength properties while maintaining workability. These steels are, however, even less resistant to corrosion and hence more susceptible to corrosion fatigue. See U.S. Pat. No. 4,718,908. Additional examples of biocompatible metals and alloys include tantalum, gold, platinum, iridium, silver, molybdenum, tungsten, inconel and nitinol . Because certain types of implants (artificial joints, artificial bones or artificial tooth roots) require high strength, metallic biomaterials have conventionally been used. However, as mentioned above, certain alloys corrode within the body and, as a result, dissolved metallic ions can produce adverse effects on the surrounding cells and can result in implant breakage. In an attempt to solve this problem, ceramic biomaterials such as alumina have been used in high- stress applications such as in artificial knee joints. Ceramic biomaterials have an excellent affinity for bone tissue and generally do not corrode in the body. But when used under the load of walking or the like, they may not remain fixed to the bone. In many cases additional surgery is required to secure the loosened implant . This shortcoming led to the development of bioactive ceramic materials. Bioactive ceramics such as hydroxyapatite and tricalcium phosphate are composed of calcium and phosphate ions (the main constituents of bone) and are readily resorbed by bone tissue to become chemically united with the bone. U.S. Pat. No. 5,397,362. However, bioactive ceramics such as hydroxyapatite and tricalcium phosphate are relatively brittle and can fail under the loads in the human body. This has led in turn to the development of non-calcium phosphate bioactive ceramics with high strength. See U.S. Pat. No. 5,711,763. Additional examples of biocompatible ceramics include zirconia, silica, calcia, magnesia, and titania series materials, as well as the carbide series materials and the nitride series materials. Polymeric biomaterials are desirable for implants because of their chemical inertness and low friction properties. However, polymers used in orthopedic devices such as hip and knee joints have a tendency for wear and build-up of fine debris, resulting in a painful inflammatory response. Examples of biocompatible polymeric materials include silicone, polyurethane, polyureaurethane, polyethylene teraphthalate, ultra high molecular weight polyethylene, polypropylene, polyester, polyamide, polycarbonate, polyorthoesters, polyesteramides, polysiloxane, polyolefin, polytetrafluoroethylene, polysulfones, polyanhydrides, polyalkylene oxide, polyvinyl halide, polyvinyledene halide, acrylic, methacrylic, polyacrylonitrile, vinyl, polyphosphazene, polyethylene-co-acrylic acid, hydrogels and copolymers . Specific applications include the use of polyethylene in hip and knee joint implants and the use of hydrogels in ocular implants. See U.S. Pat. No. 5,836,313. In addition to relatively inert polymeric materials discussed above, certain medical applications require the use of biodegradable polymers for use as sutures and pins for fracture fixation. These materials serve as a temporary scaffold which is replaced by host tissue as they are degraded. See U.S. Pat. No. 5,766,618. Examples of such biodegradable polymers include polylactic acid, polyglycolic acid, and polyparadioxanone . In addition to wholly synthetic polymers, polymers which are naturally produced by organisms have been used in several medical applications. Such polymers, including polysaccharides such as chitin, cellulose and hyaluronic acid, and proteins such as fibroin, keratin, and collagen, offer unique physical properties in the biological environment, and are also useful when a biodegradable polymer is required. In order to adapt these polymers for certain uses, many have been chemically modified, such as chitosan and methyl cellulose. These polymers have found niches in a variety of applications. Chitosan is often used to cast semi- permeable films, such as the dialysis membranes in U.S. Pat. No. 5,885,609. Fibroin (silk protein) has been used as a support member in tissue adhesive compositions, U.S. Pat. No. 5,817,303. Also, esters of hyaluronic acid have been used to create bioabsorbable scaffolding for the regrowth of nerve tissue, U.S. Pat. No. 5,879,359. As is evident from the preceding paragraphs, individual biomaterials have both desirable and undesirable characteristics. Thus, it is common to create medical devices which are composites of various biocompatible materials in order to overcome these deficiencies. Examples of such composite materials include: the implant material comprising glass fiber and polymer material disclosed in U.S. Pat. No. 5,013,323; the polymeric-hydroxyapatite bone composite disclosed in U.S. Pat. No. 5,766,618; the implant comprising a ceramic substrate, a thin layer of glass on the substrate and a layer of calcium phosphate over the glass disclosed in U.S. Pat. No. 5,397,362; and an implant material comprising carbon fibers in a matrix of fused polymeric microparticles . The diverse uses of biomaterials require a range of mechanical and physical properties for particular applications. As medical science advances, many applications will require new and diverse materials which can be safely and effectively used in biological systems . Biomaterials, especially polymers, have been chemically modified in several ways in order to give them certain biological characteristics. For instance, thrombogenesis has posed a perennial problem for the use of biomaterials in hemodialysis membranes. In order to decrease thrombogenesis, hemodialysis fluid circuit materials have been modified by ionic complexation and interpenetration of heparin, U.S. Pat. No. 5,885,609, and by graft copolymer techniques in which heparin is linked to the backbone polymer by polyethylene oxide, Park, K.D., "Synthesis and Characterization of SPUU-PEO- Heparain Graft Copolymers" , J. Polymer. Sci . , Vol. 20, p. 1725-37 (1991) . Similarly, polymers containing incorporated drugs for elution into the body have been co- implanted with stents in order to prevent restenosis, U.S. Pat. No. 5,871,535. Although most biomaterials in current use are considered non-toxic, implanted biomaterial devices are seen as foreign bodies by the immune system, and so elicit a well characterized inflammatory response. See Gristina, A.G. "Implant Failure and the Immuno- Incompetent Fibro- Inflammatory Zone" In "Clinical Orthopaedics and Related Research" (1994) , No. 298, pp. 106-118. This response is evidenced by the increased activity of macrophages, granulocytes, and neutrophils, which attempt to remove the foreign object by the secretion of degradative enzymes and free radicals like superoxide ion (0 2 ~ ) to inactivate or decompose the foreign object. Woven dacron polyester, polyurethane, velcro, polyethylene, and polystyrene were shown to elicit superoxide production from neutrophils by Kaplan, S.S., et al, "Biomaterial-induced alterations of neutrophil superoxide production" In "Jour .Bio .Mat .Res . " (1992), Vol. 26, pp. 1039-1051. To a lesser extent, polysulfone/carbon fiber and polyetherketoneketone/carbon fiber composites were shown to elicit a superoxide response by Moore, R. , et al , "A comparison of the inflammatory potential of particulates derived from two composite materials" In "Jour .Bio .Mat .Res . " (1997), Vol. 34, pp. 137-147. Hydroxyapatite, tricalcium phosphate, and aluminum-calcium-phosphorous oxide bioceramics were shown to be degraded by macrophages by Ross, L., et al , "The Effect of HA, TCP and Alcap Bioceramic Capsules on the Viability of Human Monocyte and Monocyte Derived Macrophages" in "Bio . Sci . Inst . " (1996), Vol. 32, pp. 71- 79. Similarly, cobalt-chrome alloy beads were degraded by neutrophils in a study by Shanbhag, A., et al , "Decreased neutrophil respiratory burst on exposure to cobalt-chrome alloy and polystyrene in vitro" In "Jour. Bio. Mat. Res. " (1992), Vol. 26, 2, pp. 185-195. Even biomaterials which have been modified to present biologically acceptable molecules, such as heparin, have been found to elicit an inflammatory response, Borowiec, J.W. , et al , "Biomaterial -Dependent Blood Activation During Simulated Extracorporeal Circulation: a Study of Heparin-Coated and Uncoated Circuits", Thorac . Cardiovasc. Surgeon 45 (1997) 295-301. In addition, chemical modification has posed several difficulties. Because of the unique chemical characteristics of each biomaterial and bioactive molecule, covalent linkage of the desired bioactive molecule to the biomaterial is not always possible. In addition, the activity of many bioactive molecules, especially proteins, is diminished or extinguished when anchored to a solid substrate. Finally, the fact that many biologically active substances are heat liable has prevented their use with biomaterials that are molded or worked at high temperatures . The impact of continual attempts by the organism to degrade biomaterial implants can lead to increased morbidity and device failure. In the case of polyurethane pacemaker lead wire coatings, this results in polymer degradation and steady loss of function. In the use of synthetic vascular grafts, this results in persistent thrombosis, improper healing, and restenosis. As mentioned above, orthopedic devices such as hip and knee joints have a tendency for wear and build-up of fine debris resulting in a painful inflammatory response. In addition, the surrounding tissue does not properly heal and integrate into the prosthetic device, leading to device loosening and opportunistic bacterial infections. It has been proposed by many researchers that chronic inflammation at the site of implantation leads to the exhaustion of the macrophages and neutrophils, and an inability to fight off infection. Superoxide anions are normally removed in biological systems by the formation of hydrogen peroxide and oxygen in the following reaction (hereinafter referred to as dismutation) : 0 2 ~ + 0 2 2H + → 0 2 + H 2 0 2 This reaction is catalyzed in vivo by the ubiquitous superoxide dismutase enzyme. Several non-proteinaceous catalysts which mimic this superoxide dismutating activity have been discovered. A particularly effective family of non-proteinaceous catalysts for the dismutation of superoxide consists of the manganese (II) , manganese (III) , iron(II) or iron(III) complexes of nitrogen-containing fifteen-membered macrocyclic ligands which catalyze the conversion of superoxide into oxygen and hydrogen peroxide, described in U.S. Patents Nos . 5,874,421 and 5,637,578, all of which are incorporated herein by reference. See also Weiss, R.H., et al, "Manganese (II) - Based Superoxide Dismutase Mimetics: Rational Drug Design of Artificial Enzymes", (1996) Drugs of the Future 21, 383-389; and Riley, D.P., et al, "Rational Design of Synthetic Enzymes and Their Potential Utility as Human Pharmaceuticals" (1997) in CatTech, I, 41 . These mimics of superoxide dismutase have been shown to have a variety of therapeutic effects, including anti- inflammatory activity. See Weiss, R.H., et al , "Therapeutic Aspects of Manganese (II) -Based Superoxide Dismutase Mimics" In "Inorganic Chemistry in Medicine", (Farrell, N. , Ed.), Royal Society of Chemistry, in Press; Weiss, R.H., et al , "Manganese-Based Superoxide Dismutase Mimics: Design, Discovery and Pharmacologic Efficacies" (1995) In "The Oxygen Paradox (Davies, K.J.A., and Ursini, F., Eds.) pp. 641-651, CLEUP University Press, Padova, Italy; Weiss, R.H., et al, "Manganese-Based Superoxide Dismutase Mimetic Inhibit Neutrophil Infiltration In Vitro", J.Biol.Chem. , 271, 26149 (1996); and Hardy, M.M., et al, "Superoxide Dismutase Mimetics Inhibit Neutrophil - Mediated Human Aortic Endothelial Cell Injury In Vitro", (1994) J.Biol.Chem. 269, 18535-18540. Other non- proteinaceous catalysts which have been shown to have superoxide dismutating activity are the salen-transition metal cation complexes, described in U.S. Patent No. 5,696,109, and complexes of porphyrins with iron and manganese cations. SUMMARY OF THE INVENTION Applicants have discovered that the modification of biomaterials with non-proteinaceous catalysts for the dismutation of superoxide greatly improves the biomaterial ' s resistance to degradation and reduces the inflammatory response. Thus, the present invention is directed to biomaterials which have been modified with non-proteinaceous catalysts for the dismutation of superoxide, or precursor ligands of non-proteinaceous catalysts for the dismutation of superoxide. The present invention is directed to biomaterials which have been modified with non-proteinaceous catalysts for the dismutation of superoxide, or precursor ligands of a non-proteinaceous catalyst for the dismutation of superoxide, by utilizing methods of physical association, such as surface covalent conjugation, copolymerization, and physical admixing. The present invention is also directed to biomaterials modified with non-proteinaceous catalysts for the dismutation of superoxide wherein one or more of these methods has been used to modify the biomaterial . A variety of biomaterials are appropriate for modification in the present invention.

The term "non-proteinaceous catalysts for the dismutation of superoxide" means a low-molecular-weight catalyst for the conversion of superoxide anions into hydrogen peroxide and molecular oxygen. These catalysts commonly consist of an organic ligand and a chelated transition metal ion, preferably manganese or iron.

Modification may be effected by surface covalent conjugation, copolymerization, admixture, or by other methods. When modification is achieved by admixture, it is understood that the non-proteinaceous catalyst is in the same phase as at least a part of the biomaterial that is modified. The term "surface covalent conjugation" means that the non-proteinaceous catalyst is bound through at least one covalent bond to the surface of a biomaterial.

DETAILED DESCRIPTION OF THE INVENTION The present invention concerns novel modified biomaterials and methods for the production of such materials. Prior to applicants' invention, it was not known that non-proteinaceous catalysts for the dismutation of superoxide could be immobilized on the surface of a biomaterial and still retain their catalytic function and exhibit an anti- inflammatory effect. However, applicants have found that these catalysts can be efficaciously immobilized on biomaterial surfaces and still retain superoxide dismutating ability, as shown by Example 23. Applicants have also found that these modified biomaterials have greatly improved durability and decreased inflammatory response when exposed to biological systems, such as the rat model in Examples 21 and 22. Biomaterials and Non-Proteinaceous Catalysts for the Dismutation of Superoxide for Use in the Present Invention A variety of biomaterials are appropriate for modification in the present invention.

Applicants have discovered that these compounds, especially the preferred pentaaza non-proteinaceous catalysts, will survive a wide range of chemical reactions and processing conditions including extreme chemical and thermal conditions. Particularly, the PACPeD catalysts have been demonstrated by the applicants to be stable at temperatures up to about 350°C, and at pH of about 4. Additionally, the PACPeD' s are soluble in a wide range of solvents, including water, methanol , ethanol, methylene chloride, DMSO, DMF, and DMAC, and are partially soluble in toluene and acetonitrile . By adding polar or non-polar substituents at the R group positions on the PACPeD or other non-proteinaceous catalysts, applicants have improved their solubility in specific solvents for particular reactions, and for use with particular biomaterials. As illustrated by Table 1 below, several reactive functional groups may be added as pendant moieties without detrimentally affecting the catalyst's superoxide dismutating ability. The non-proteinaceous catalysts for the dismutation of superoxide for use in the present invention preferably comprise an organic ligand and a transition metal cation.

Thus, the PACPeD' s useful in the present invention can have any combinations of substituted or unsubstituted R groups, saturated, partially saturated or unsaturated cyclics, ring structures, nitrogen containing heterocycles, or straps as defined above. X, Y and Z represent suitable ligands or charge-neutralizing anions which are derived from any monodentate or polydentate coordinating ligand or ligand system or the corresponding anion thereof (for example benzoic acid or benzoate anion, phenol or phenoxide anion, alcohol or alkoxide anion) . X, Y and Z are independently selected from the group consisting of halide, oxo, aquo, hydroxo, alcohol, phenol, dioxygen, peroxo, hydroperoxo, alkylperoxo, arylperoxo, ammonia, alkylamino, arylamino, heterocycloalkyl amino, heterocycloaryl amino, amine oxides, hydrazine, alkyl hydrazine, aryl hydrazine, nitric oxide, cyanide, cyanate, thiocyanate, isocyanate, isothiocyanate, alkyl nitrile, aryl nitrile, alkyl isonitrile, aryl isonitrile, nitrate, nitrite, azido, alkyl sulfonic acid, aryl sulfonic acid, alkyl sulfoxide, aryl sulfoxide, alkyl aryl sulfoxide, alkyl sulfenic acid, aryl sulfenic acid, alkyl sulfinic acid, aryl sulfinic acid, alkyl thiol carboxylic acid, aryl thiol carboxylic acid, alkyl thiol thiocarboxylic acid, aryl thiol thiocarboxylic acid, alkyl carboxylic acid (such as acetic acid, trifluoroacetic acid, oxalic acid) , aryl carboxylic acid (such as benzoic acid, phthalic acid) , urea, alkyl urea, aryl urea, alkyl aryl urea, thiourea, alkyl thiourea, aryl thiourea, alkyl aryl thiourea, sulfate, sulfite, bisulfate, bisulfite, thiosulfate, thiosulfite, hydrosulfite, alkyl phosphine, aryl phosphine, alkyl phosphine oxide, aryl phosphine oxide, alkyl aryl phosphine oxide, alkyl phosphine sulfide, aryl phosphine sulfide, alkyl aryl phosphine sulfide, alkyl phosphonic acid, aryl phosphonic acid, alkyl phosphinic acid, aryl phosphinic acid, alkyl phosphinous acid, aryl phosphinous acid, phosphate, thiophosphate, phosphite, pyrophosphite, triphosphate, hydrogen phosphate, dihydrogen phosphate, alkyl guanidino, aryl guanidino, alkyl aryl guanidino, alkyl carbamate, aryl carbamate, alkyl aryl carbamate, alkyl thiocarbamate aryl thiocarbamate, alkyl aryl thiocarbamate, alkyl dithiocarbamate, aryl dithiocarbamate, alkyl aryl dithiocarbamate, bicarbonate, carbonate, perchlorate, chlorate, chlorite, hypochlorite, perbromate, bromate, bromite, hypobromite, tetrahalomanganate , tetrafluoroborate , hexafluorophosphate, hexafluoroantimonate, hypophosphite, iodate, periodate, metaborate, tetraaryl borate, tetra alkyl borate, tartrate, salicylate, succinate, citrate, ascorbate, saccharinate, amino acid, hydroxamic acid, thiotosylate, and anions of ion exchange resins. The preferred ligands from which X, Y and Z are selected include halide, organic acid, nitrate and bicarbonate anions . The "R" groups attached to the carbon atoms of the macrocycle can be in the axial or equatorial position relative to the macrocycle. When the "R" group is other than hydrogen or when two adjacent "R" groups, i.e., on adjacent carbon atoms, together with the carbon atoms to which they are attached form a saturated, partially saturated or unsaturated cyclic or a nitrogen containing heterocycle, or when two R groups on the same carbon atom together with the carbon atom to which they are attached form a saturated, partially saturated or unsaturated ring structure, it is preferred that at least some of the "R" groups are in the equatorial position for reasons of improved activity and stability. This is particularly true when the complex contains more than one "R" group which is not hydrogen. Where the modification of the biomaterial is effected by the surface covalent conjugation or copolymerization with the unmodified biomaterial, it is preferred that the PACPeD contain a pendant reactive moiety. This reactive moiety may be on a "R" group, a cyclic, a heterocyclic, a nitrogen containing heterocyclic, or a strap structure as described above. Preferred moieties on the non-proteinaceous catalyst for use in the present invention include of amino (-NH 2 ), carboxyl (-OCOH) , isocyanate (-NCO) , mercapto (-SH) , hydroxy (-OH) , silyl chloride (-SiCl 2 ) , acid halide (-OCX wherein X= Cl , F, Br, I), halide (-X wherein X= Cl , F, Br, I) , glycidyl (-HCOCH 2 ) , and substituted or unsubstituted alkenyl, alkynyl, and aryl moieties. Preferred PACPeD' s for modification of biomaterials compounds are those wherein at least one "R" group contains a reactive functional group, and those wherein at least one, of R or R' and R ± or R' lf R 2 or R' 2 and R 3 or R' 3 , R 4 or R' 4 and R 5 or R' 5 , R 6 or R' 6 and R 7 or R' 7 , and R 8 or R' 8 and R 9 or R' 9 together with the carbon atoms to which they are attached are bound to form a nitrogen containing heterocycle having 2 to 20 carbon atoms and all the remaining "R" groups are independently selected from hydrogen, saturated, partially saturated or unsaturated cyclic or alkyl groups. Examples of PACPeD catalysts useful in making the modified biomaterials of the invention include, but are not limited to, the following compounds: TABLE 1 Activity of the non-proteinaceous catalysts for the dismutation of superoxide can be demonstrated using the stopped- flow kinetic analysis technique as described in Example 24, and in Riley, D. P., Rivers, W. J. and Weiss, R. H., "Stopped-Flow Kinetic Analysis for Monitoring Superoxide Decay in Aqueous Systems," Anal. Biochem. , 196, 344-349 (1991), which is incorporated by reference herein. Stopped-flow kinetic analysis is an accurate and direct method for quantitatively monitoring the decay rates of superoxide in water. The stopped- flow kinetic analysis is suitable for screening compounds for SOD activity and activity of the compounds or complexes of the present invention, as shown by stopped-flow analysis, correlate to usefulness in the modified biomaterials and processes of the present invention. The catalytic constants given for the exemplary compounds in the table above were determined using this method. As can be observed from the table, a wide variety of PACPeD' s with superoxide dismutating activity may be readily synthesized. Generally, the transition metal center of the catalyst is thought to be the active site of catalysis, wherein the manganese or iron ion cycles between the (II) and (III) states. Thus, as long as the redox potential of the ion is in a range in which superoxide anion can reduce the oxidized metal and protonated superoxide can oxidize the reduced metal, and steric hindrance of the approach of the superoxide anion is minimal, the catalyst will function with a k cat of about 10 "6 to 10 ~8 . Without limiting themselves to any particular theory, applicants propose that the mechanism described in Riley, et al . , 1999, is a reasonable approximation of how the PACPeD catalysts dismutate superoxide. In order for the complex to exhibit superoxide dismutase activity, the ligand should be able to fold into a conformation that allows the stabilization of an octahedral complex between the superoxide anion and the five nitrogens of the ligand ring. If a compound contains several conjugated double bonds within the main 15-membered ring of the ligand, which hold the ring in a rigid conformation, the compound would not be expected to exhibit catalytic activity. R groups which are coordinated with the transition metal ion freeze the conformation of the ligand, and would be expected to be poor catalysts. Large, highly electronegative groups pendant on the macrocycle would also sterically hinder the necessary conformational change. The lack of functionality in these types of PACPeD derivatives would not be unexpected by one of ordinary skill in the art. Specifically, one of skill in the art would avoid materially changing the flexibility of the PACPeD by adding many large groups which would cause steric hindrance, or placing too many double bonds into the main PACPeD ring. This effect would also be present in certain geometric arrangements of smaller R groups which constrain the complex to a rigid, planar geometry. Those particular compounds which do not exhibit superoxide dismutase activity should not be used to modify the biomaterials of the present invention. Given these examples and guidelines, one of ordinary skill would be able to choose a PACPeD catalyst for use in the present invention which would contain any required functional group, while still retaining superoxide dismutating activity. The PACPeD catalysts described above may be produced by the methods disclosed in U.S. Pat. No. 5,610,293. However, it is preferred that the PACPeD catalysts used in the present invention be synthesized by the template method, diagramed below. This synthesis method is advantageous over previously disclosed methods in that cyclization yields utilizing the template method are usually about 90%, as compared to about 20% with previous methods. Several diamines are commercially available as starting materials, or a diamine may be synthesized. The diamine is reacted with titryl chloride in anhydrous methylene chloride at 0°C and allowed to warm to room temperature overnight, with stirring. The product is then combined with glyoxal in methanol and stirred for 16 hours. The glyoxal bisimine product is then reduced with a borohydride in THF . If a non-symmetrical product is desired, two diamines may be used as starting materials. In addition, a substituted glyoxal may be used if groups pendant from the macrocycle opposite the pyridine are desired (R 5 and R 4 ) Commercially available tetraamines may also be used in place of the reduced glyoxal bisimine. After reduction of the glyoxal bisimine, the product is combined with a 2,6 dicarbonyl substituted pyridine, such ?.s 2,6, dicarboxaldyhyde pyridine or 2 , 6 diacetyl pyridine, and a salt of manganese or iron under basic conditions. The transition metal ion serves as a template to promote cyclization of the substituted pyridine and the tetraamine. Several 2,6 dicarbonyl substituted pyridines are available commercially, allowing for the facile production of a variety of ligands with groups pendant from the macrocycle proximal to the pyridine (R 2 and R 3 ) . Additionally, pyridines with additional substitutions (R s , R 7 and R 8 ) may also be used. After cyclization, the product is reduced with ammonium formate and a palladium catalyst over a period of 3-4 days. In addition to the "R" substitutions, "R'" groups may also be substituted at the same carbons. "R" and "R' " groups may be any of those indicated above. The process may be varied according to principles well known to one of ordinary skill in the art in order to accommodate various starting materials . TrtCI Although the bisimine produced in the template cyclization reaction step above may be reduced by more conventional means using hydrogen gas, it is preferred that the bisimine be reduced with ammonium formate in the presence of a palladium catalyst, as illustrated in Example 6. This process offers the advantages of increased safety and high reduction efficiency. The PACPeD' s useful in the present invention can possess one or more asymmetric carbon atoms and are thus capable of existing in the form of optical isomers as well as in the form of racemic or nonracemic mixtures thereof. The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example by formation of diastereoisomeric salts by treatment with an optically active acid. Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric and camphorsulfonic acid and then separation of the mixture of diastereoisomers by crystallization followed by liberation of the optically active bases from these salts. A different process for separation of optical isomers involves the use of a chiral chromatography column optimally chosen to maximize the separation of the enantiomers. Still another available method involves synthesis of covalent diastereoisomeric molecules by reacting one or more secondary amine group (s) of the compounds of the invention with an optically pure acid in an activated form or an optically pure isocyanate. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization or sublimation, and then hydrolyzed to deliver the enantiomerically pure ligand. The optically active compounds of the invention can likewise be obtained by utilizing optically active starting materials, such as natural amino acids. Also suitable for use in the present invention, but less preferred than the PACPeD' s, are the salen complexes of manganese and iron disclosed in U.S. Patent No. 5,696,109, here incorporated by reference. The term "salen complex" means a ligand complex with the general formula : wherein M is a transition metal ion, preferably Mn; A is an anion, typically Cl ; and n is either 0, 1, or 2. X 1 , X 2 , X 3 and X 4 are independently selected from the group consisting of hydrogen, silyls, arlyls, aryls, arylalkyls, primary alkyls, secondary alkyls, tertiary alkyls, alkoxys, aryloxys, aminos, quaternary amines, heteroatoms, and hydrogen; typically X λ and X 3 are from the same functional group, usually hydrogen, quaternary amine, or tertiary butyl, and X 2 and X 4 are typically hydrogen. Y lf Y 2 , Y 3 , Y 4 , Y 5 , and Y 6 are independently selected from the group consisting of hydrogen, halides, alkyls, aryls, arylalkyls, silyl groups, aminos, alkyls or aryls bearing heteroatoms; aryloxys, alkoxys, and halide; preferably, Y__ and Y 4 are alkoxy, halide, or amino groups. Typically, Y λ and Y 4 are the same. R , R 2 , R 3 and R 4 are independently selected from the group consisting of H, CH 3 , C 2 H 5 , C 6 H 5 , O-benzyl, primary alkyls, fatty acid esters, substituted alkoxyaryls, heteroatom-bearing aromatic groups, arylalkyls, secondary alkyls, and tertiary alkyls. Methods of synthesizing these salen complexes are also disclosed in U.S. Patent No. 5,696,109. Iron or manganese porphyrins, such as , such as Mn 111 tetrakis (4 -N-methylpyridyl) porphyrin, Mn 111 tetrakis-o- (4- N-methylisonicotinamidophenyl) porphyrin, Mn 111 tetrakis (4- N-N-N-trimethylanilinium) porphyrin, Mn 111 tetrakis (1- methyl-4 -pyridyl) porphyrin, Mn 111 tetrakis (4-benzoic acid) porphyrin, Mn 11 octabromo-meso-tetrakis (N- methylpyridinium-4 -yl) porphyrin, Fe 111 tetrakis (4-N- methylpyridyl) porphyrin, and Fe 111 tetrakis-o- (4-N- methylisonicotinamidophenyl) porphyrin. may also be used in the present invention. The catalytic activities and methods of purifying or synthesizing these porphyrins are well known in the organic chemistry arts. The salen and porphyrin non-proteinaceous catalysts for the dismutation of superoxide also preferably contain a reactive moiety, as described above, when the methods of surface covalent conjugation or copolymerization are used to modify the biomaterial. In general, the non-proteinaceous catalysts for the dismutation of superoxide used in the present invention are very stable under conditions of high heat, acid or basic conditions, and in a wide variety of solvents. However, under extreme reaction conditions the chelated transition metal ion will dissociate from the non- proteinaceous catalyst. Thus, when extreme reaction conditions are necessary to modify the biomaterial, it is preferable to modify the biomaterial with a precursor ligand of the non-proteinaceous catalyst for the dismutation of superoxide, and then afterwards react the modified biomaterial with a compound containing the appropriate transition metal in order to produce a biomaterial modified with an active non-proteinaceous catalyst for the dismutation of superoxide For instance, when a PACPeD catalyst is used under reaction conditions of pH < 4, the strategy of modifying the biomaterial with the ligand should be used. This strategy is demonstrated in Example 19. Therefore, when the term non-proteinaceous catalyst for the dismutation of superoxide is used in this specification, the reader should assume that, where appropriate, the precursor ligand will be used in the modification of the biomaterial, and that the transition metal cation necessary for activity may be added at a later point in time. Conditions where this approach would be appropriate may be readily determined by one of ordinary skill in the chemical arts. Choice of Method of Modification As previously described, the biomaterials of the present invention may be modified by the diverse methods of surface covalent conjugation, copolymerization, or admixture. The methods of surface covalent conjugation and copolymerization use covalent bonds in order to physically associate the non-proteinaceous catalyst for the dismutation of superoxide with the biomaterial. This creates a very stable physical association which preserves the superoxide dismutating activity of the modified biomaterial. In contrast, non-covalent forces create the physical association between the biomaterial and the non-proteinaceous catalysts for the dismutation of superoxide when the technique of physical admixture is used. These non-covalent forces may be weak Van der Wal ' s forces, or they may be stronger ionic bonding or hydrophobic interaction forces. Although ionic or hydrophobic interactions between the non-proteinaceous catalyst and the biomaterial will prevent elution of the non-proteinaceous catalyst to some degree, the catalyst will still be lost from the biomaterial over time when the biomaterial is exposed to biological tissues or fluids. Thus, it is usually preferred that the methods of covalent surface conjugation or copolymerization be used to modify biomaterials which will be exposed to biological systems for prolonged periods of time. However, uses may arise where the elution of non- proteinaceous catalysts for the dismutation of superoxide into the tissues surrounding an article comprising the modified biomaterial may be desirable. In this case, the use of biomaterials modified by the physical admixture method would be appropriate. When composite materials are used, it may be necessary to utilize a variety of modification techniques. For instance, in a biomaterial composed of hydroxyapatite and polyethylene, a non-proteinaceous catalyst may be admixed with the hydroxyapatite phase of the composite, and another copolymerized with the polyethylene phase of the composites. The two composites may then be joined together into a fully modified composite biomaterial. Similarly, a composite material which utilizes carbon fiber and polypropylene could be made using a copolymerized polypropylene and a surface covalently conjugated carbon fiber. The flexibility in the production of modified biomaterials offered by the processes of the invention allows for the use of several diverse materials in a device while increasing its durability and decreasing the inflammatory response to the device. Generally, it is preferred that the non- proteinaceous catalyst be present in an amount of about 0.001 to 25 weight percent. It is more preferable that the catalyst be present in an amount of about 0.01 to 10 weight percent. It is most preferable that the catalyst be present in an amount of about 0.05 to 5 weight percent. However, the amount of the non-proteinaceous catalyst to be used in modifying the biomaterial will depend on several factors, including the characteristics of the catalyst, the characteristics of the biomaterial, and the method of modification used. As is evident from the chart above, the catalytic activity of the non- proteinaceous catalysts for use in the present invention may vary over several orders of magnitude. Thus, less of the more efficient catalysts will be needed to obtain the same protective effects. Also, some biomaterials are more inflammatory than others. Thus, a greater amount of catalyst should be used with these biomaterials in order to counteract the strong inflammatory foreign body response that they provoke. In addition, the amount of catalyst used to modify the biomaterial should not be so high as to significantly alter the mechanical characteristics of the biomaterial . Because a covalently conjugated catalyst is concentrated at the surface of the biomaterial used in a device, almost all of the catalyst will interact with the biological environment. Conversely, because an admixed or copolymerized catalyst is dispersed throughout the biomaterial, less of the catalyst will be available to interact with the biological environment at the surface of the biomaterial . Thus, when the catalyst is covalently conjugated to the surface of the biomaterial, less catalyst will be needed than if the catalyst is admixed or copolymerized with the biomaterial. Given the above considerations, the person of ordinary skill in the art would be able to choose a proper amount of non-proteinaceous catalyst to use in the present invention in order to achieve the desired reduction in the inflammatory response and degradation. It is to be understood that although the non- proteinaceous catalysts used in the following processes are usually referred to in the singular, multiple catalysts may be used in any of these processes. One of ordinary skill in the art will easily be able to choose complementary catalysts for such modified biomaterials. In addition, although not specifically enumerated herein, the combination of the biomaterial modification techniques of the present invention with other biomaterial modification techniques, such as heparin coating, is contemplated within the present invention. Modification by Surface Covalent Conjugation The general process for producing a biomaterial modified by surface covalent conjugation with at least one non-proteinaceous catalyst for the dismutation of superoxide or at least one precursor ligand of a non- proteinaceous catalyst for the dismutation of superoxide, comprises : a. providing at least one reactive functional group on a surface of the biomaterial to be modified; b. providing at least one complementary reactive functional group on the non-proteinaceous catalyst for the dismutation of superoxide or on the precursor ligand; and c. conjugating the non-proteinaceous catalyst for the dismutation of superoxide or the precursor ligand with the surface of the biomaterial through at least one covalent bond. This process may be effected by a photo-chemical reaction, or any of a number of conjugating reactions known in the art, such as condensation, esterification, oxidative, exchange, or substitution reactions. Preferred conjugation reactions for use in τ;he present invention do not involve extreme reaction conditions, such as a temperature above about 375°C, or pH less than about 4. In addition, it is preferred that the conjugation reaction not produce a covalent bond that is readily cleaved by common enzymes found in biological systems. Usually, it is desirable for the non- proteinaceous catalyst to have only one complementary functional group. However, in cases where crosslinking of the biomaterial is desired, such as in hydrogels, poly-functional -group catalysts may be used. Care should be taken, however, to choose functional groups which will not allow the non-proteinaceous catalyst to self- polymerize, as this will decrease the efficiency of the conjugation reaction. Likewise, multiple non- proteinaceous catalysts may be used to modify the biomaterial, although complementary functional groups which allow avoid inter-catalyst conjugations would not be preferred. The non-proteinaceous catalyst for the dismutation of superoxide or the precursor ligand may be covalently bound directly to the surface of the biomaterial, or bound to the surface through a linker molecule. Where the non-proteinaceous catalyst and the surface of the biomaterial are directly conjugated, the reactive functional group and the complementary reactive functional group will form a covalent bond in the conjugation reaction. For instance, poly (ethyleneterephthalate) may be hydrolyzed to carboxyl functional groups. Compound 43 may then be reacted with the derivatized polymer to form the amide bond, as illustrated in Example 7. Examples H and E also illustrate a direct surface covalent conjugation. Further suggestions for reactive groups to use in of direct conjugation may be found in U.S. Pat. No. 5,830,539, herein incorporated by reference. Several exemplary paired functional groups are given in Table 2 : TABLE 2 SODm—NH, R—N=C=S H S R N—C N—SODm SODm—OH R—N--=C=0 H O R N—C O—SODm SODr O O OH R—C—O—SODm SODn O OH R CH—CH, R—CH—CH 2 —0—SODm SODi OH R—N=C=S H S N—C—O—SODm SODm—OH R C—O—SODm SODm—OH R—Si — (OCH 3)'3 R—Si—-(O—SODm) 3 When a linker molecule is used, the above process further comprises providing at least one linker capable of reacting with both the reactive functional group on a surface of the biomaterial to be modified and the complementary reactive functional group on the non- proteinaceous catalyst for the dismutation of superoxide or the precursor ligand. During the conjugation process, the reactive functional group on the surface of the article and the complementary reactive functional group on the non-proteinaceous catalyst for the dismutation of superoxide form a covalent bond with the linker. This process may occur all in one step, or in a series of steps. For instance, in a two step process, a carboxyl functionalized polymer, such as a hydrolyzed poly (ethyleneterephthalate) polymer ("PET") could first be reacted with a (Gly) 12 linker in an amide reaction. Then, after removal of excess linker, the PET- glycine linker could react with an amino PACPeD such as Compound 43 to form a polymer-glycine linker-Compound 43 modified biomaterial. Alternately, the hydrolyzed PET could be linked with a low molecular weight PEG to a carboxyl PACPeD such as Compound 52 by an ester reaction in a single step. Linkers suitable for use in this process include polysaccharides, polyalkylene glycols, polypeptides, polyaldehydes, and silyl groups. Silyl groups are particularly useful in conjugating non- proteinaceous catalysts with metal biomaterials. Examples of linkers and functional groups which are useful in the present invention may be found in U.S. Pat. Nos. 5,877,263 and 5,861,032. Persons of ordinary skill in the chemical arts will be able to determine an appropriate linker and non-proteinaceous catalyst for conjugation to any biomaterial, including metals, ceramics, polymers, biopolymers, and various phases of composites . This method of modification may be used with an article which is already in its final form, or may be used with parts of an article before final assembly. In addition, this method is useful for modifying thin stock materials which will be used in the later manufacture of a device, such as polymer or chitosan films, or fibers which will be woven into fabrics for vascular grafts. This method is also useful for modifying diverse materials in a single step with one non-proteinaceous catalyst. For instance, a tantalum component which has been reacted with a silyl linker, as in Example 13, and a poly (ethyleneterephthalate) component which has been hydrolyzed, as in Example 7, may be assembled into a final device. Then, Compound 43 could be reacted with the entire article to modify the surface of both materials in a single step. Modification by Copolymerization Biomaterials may also be modified according to the present invention by co-polymerization with a non- proteinaceous catalyst for the dismutation of superoxide or the ligand precursor of a non-proteinaceous catalyst for the dismutation of superoxide. This process, inc general, comprises: a. providing at least one monomer; b. providing at least one least one non- proteinaceous catalyst for the dismutation of superoxide or at least one ligand precursor of a non-proteinaceous catalyst for the dismutation of superoxide containing at least one functional group capable of reaction with the monomer and also containing at least one functional group capable of propagation of the polymerization reaction, c. copolymerizing the monomers and the non- proteinaceous catalyst for the dismutation of superoxide or the ligand precursor in a polymerization reaction. The copolymerization technique is advantageous for the modification of polymers and synthetic biopolymers with non-proteinaceous catalysts for the dismutation of superoxide. However, it is preferred that this method be used with polymers whose polymerization reaction occurs at temperatures less than about 375°C, and pH greater than about 4. If the polymerization reaction is carried out at a pH less than 4, a ligand precursor of the non- proteinaceous catalysts for the dismutation of superoxide should be used. Monomers useful in this process include alkylenes, vinyls, vinyl halides, vinyledenes, diacids, acid amines, diols, alcohol acids, alcohol amines, diamines, ureas, urethanes, phthalates, carbonic acids, orthoesters, esteramines, siloxanes, phosphazenes, olefins, alkylene halides, alkylene oxides, acrylic acids, sulfones, anhydrides, acrylonitriles , saccharides, and amino acids. As demonstrated previously, the non-proteinaceous catalysts for the dismutation of superoxide used in the present invention may be synthesized with any functional group necessary to react with the any of these monomers . In order to prevent the termination of the polymerization reaction, it is necessary that the non-proteinaceous catalyst also contain a polymerization propagation functional group. Often, this will be another functional group identical to the first functional group, as in the diamine PACPeD Compound 16. This catalyst is copolymerized with polyureaurethane in Example 16. However, as when the polymerization reaction involves a vinyl reaction, the reactive and propagative functional groups may be the same, such as in the acryloyl derivatized Compound 53. Copolymerization of this catalyst with acrylic or methacrylic is shown in Example 17. Example 18 also illustrates the modification of biomaterials by copolymerization with non-proteinaceous catalysts . Biomaterials modified by copolymerization have several advantages. First, the non-proteinaceous catalysts for the dismutation of superoxide are covalently bound to the modified biomaterial, preventing dissociation of the catalysts and a loss of function. Second, the modification of the material is continuous throughout the biomaterial, allowing for continuous protection by the catalyst if the exterior surface of the material is by mechanical or chemical degradation. Third, the material can be melted and re-formed into any useful article after modification, provided that the polymer melts below about 375°C. Alternatively, wet- spinning or solvent casting may be used to make articles from these modified polymer biomaterials. These characteristics make the modified polymer biomaterials produced by this process a versatile tool for various medical device applications. Modification by Admixture The biomaterials of the present invention may also be modified by admixture with at least one non- proteinaceous catalyst for the dismutation of superoxide or a precursor ligand of a non-proteinaceous catalyst for the dismutation of superoxide. The general process comprises : a. providing at least one unmodified biomaterial; b. providing at least one non-proteinaceous catalyst for the dismutation of superoxide or at least one ligand precursor of a non- proteinaceous catalyst for the dismutation of superoxide; and c. admixing the unmodified biomaterial and the non-proteinaceous catalyst for the dismutation of superoxide or the ligand precursor. Biomaterials modified according to this process preferably form a solution with the non-proteinaceous catalyst or ligand, although a μm to nm-sized particle mixture is also contemplated by the present invention. The above admixture process may involve heating the constituents in order to melt at least one unmodified biomaterial constituent. For instance, the PACPeD catalyst Compound 38 can be mixed with melted polypropylene at 250°C, as in Example 20. Many other polymer biomaterials melt below 300°C, such as polyethylene, poly (ethyleneterephthalate) and polyamides, and would be especially suitable for use in this melted admixture technique. After admixing, the melted modified biomaterial may be injection or extrusion molded, or spun. Temperatures above about 375°C should not be used, however, as decomposition of the catalyst may result. Thus, metals, ceramics, and high-melt polymers should not be melted for admixture. Rather, a solvent in which at least one unmodified biomaterial and the non- proteinaceous catalyst for the dismutation of superoxide or the ligand precursor are soluble may be used when admixing these constituents. As noted above, the PACPeD catalysts are soluble in several common solvents. If the solvent method is used, the process preferably further comprises removing the solvent after admixing. Methods suitable for removing a solvent used in the present invention include evaporation and membrane filtration, although care should be taken so that the membrane filter size will retain the non-proteinaceous catalyst. As with the copolymerized modified biomaterials, the admixed modified biomaterials may be wet spun or solution cast. More hydrophobic or hydrophilic groups may be added to the non-proteinaceous catalyst in order to change its solubility characteristics. Likewise, the non- proteinaceous catalysts may be synthesized with specific pendant groups in order to have a particular affinity for the modified biomaterial. Usually this is accomplished by choosing the non-proteinaceous catalyst used in the admixture process so that ionic or hydrophobic interactions will occur between the catalysts and the modified biomaterial. For instance, the negatively charged carboxyl group of Compound 52 would have an affinity for the positively charged calcium ions in a hydroxyapatite ceramic matrix. Similarly, the added cyclohexyl group of Compound 47, as well as the lack of pendant polar groups, would help this catalyst to integrate into polyethylene. Thus, by increasing the affinity of the non-proteinaceous catalyst for the biomaterial, one can help to prevent the dissociation of the catalyst from the modified biomaterial. Uses of the Modified Biomaterials The biomaterials of the present invention show greatly improved durability and decreased inflammatory response when interacting with biological systems. Thus, these biomaterials modified with non-proteinaceous catalysts for the dismutation of superoxide are ideal for use in devices for implantation or the handling of bodily fluids. Since the non-proteinaceous catalysts for the dismutation of superoxide are not consumed during the dismutation reaction, they may retain their activity indefinitely. The biocompatible article can be an article where, during its intended use, at least a portion of the article comprising the modified biomaterial is implanted within a mammal. For instance, one such application would be coating pacemaker lead wires as described in U.S. Pat. No. 5,851,227 with the modified polyureaurethane of Example 16. These improved lead wires are believed to be more durable in the body, and thus prevent the device failure which is often seen with conventional polyurethane coated wires. Similarly, a modified polyester, such as in Example 19, could be used to spin fibers for vascular graft fabric as described in U.S. Pat. No. 5,824,047. Grafts made using this fabric are believed to heal faster, as less inflammation would be caused by the biomaterial . Similarly, the modified polypropylene tested in Example 22 could be used to make surgical sutures. The biocompatible article may also be one where, during its intended use, the surface comprising the modified biomaterial is exposed to biological fluids, such as blood or lymph. For instance, a surface covalently conjugated chitosan film would be ideal for use as a membrane material in heart -lung machines which oxygenate and circulate blood during bypass operations. The copolymerized poly (etherurethane urea) of Example 16 would be useful in manufacturing the direct mechanical bi-ventricular cardiac assist device of U.S. Pat. No. 5,749,839. Use of these biomaterials in tissue engineering devices, such as scaffoldings, would be another application. The various methods of modifying biomaterials provided by the invention allow for a wide range of practical applications. For instance, in manufacturing stents for use in angioplasty procedures, one would have the option of directly conjugating a PACPeD with a pendant silyl group with the steel of a stent manufactured as described in U.S. Pat. No. 5,800,456, through the formation of a covalent bond. Alternatively, one could copolymerize a PACPeD with pendant amine groups with a polyurethane, as in Example 16, and coat the stent with the polymer. Yet another option would be to admix a PACPeD with polypropylene, as in Example 20, extrude the mixture into a stretchable film, and shrink wrap the stent in the modified polymer film. As shown by this simple example, the diverse processes for the production of modified biomaterials using non-proteinaceous catalysts for the dismutation of superoxide allow the bio-engineer a wide variety of manufacturing techniques. A person of ordinary skill in the art of medical device design would be able to discern which modified material, and which process of modification, would be best for the medical device being produced. The biocompatible articles of the present invention may comprise several biomaterials modified with a non- proteinaceous catalyst for the dismutation of superoxide or a ligand precursor of a non-proteinaceous catalyst for the dismutation of superoxide. This versatility will make these materials especially useful in medical devices that are subject to continual wear and stress, such as joint replacement implants. The polyethylene "socket" polymer portion of the joint which allows a lowered friction contact point in the implant could be injection molded from a copolymer with the non-protemaceous catalyst, while the metal "ball" portion of the joint which contacts the polyethylene could be surface covalently conjugated with a non-proteinaceous catalyst. Thus, an entire device with decreased inflammatory response may be manufactured out of the modified biomaterials of the present invention, even though diverse materials are used in its construction. Another use for the modified biomaterials, mentioned in the stent example above, is coatings.

The dried salt is heated in a suitable reactor with good stirring first to 2150°C for about an hour and then to 2700°C. After 30-60 minute heating under atomospheric pressure, the heating is continued under vacuum for about an hour. The polymer is then cooled under nitrogen and recovered. EXAMPLE 19 COPOLYMERIZATION OF COMPOUND 27 WITH TETRAMETHYLENE GLYCOL AND ISOPHTHALATE A three necked flask equipped with a nitrogen inlet tube extending below the surface of the reaction mixture, a mechanical stirrer, and an exit tube for nitrogen and evolved hydrogen chloride is flushed with nitrogen and charged first with a isophthaloyl chloride followed by a stoichiometric amount of a mixture of tetramethylene glycol and Compound 27 ligand. The heat of reaction would cause the isophthaloyl chloride to melt. The reaction is stirred vigorously and nitrogen is passed through the reaction mixture to drive away the hydrogen chloride (and collected in an external trap) . The temperature of the reaction is then raised to 180°C and held at that temperature for 1 hour. During the last 10 minutes of the 180°C heating cycle, the last of the hydrogen chloride is removed by reducing the pressure to 0.5 - 1.0 mm. The copolymer is obtained as a white solid. Compound 27 in the polymer backbone is then complexed with manganese chloride . EXAMPLE 20 ADMIXTURE OF COMPOUND 38 WITH POLYPROPYLENE Compound 38 was determined to be thermally stable up to 350°C. 0.105 g of Compound 38 was added to 4.9 g of cryoground polypropylene. The mixture was melted at 250 °C and extruded into a strand and a fiber. In this manner, a polypropylene modified with a non-proteinaceous catalyst, 2% by weight, was made. The product strand was cryoground and extracted with pure water. Active Compound 38, as confirmed by both stopped-flow kinetic analysis and HPLC-UN spectroscopy, was extracted from the strand. The concentration of Compound 38 in the water was has been calculated to correspond to approximately a 10% elution of the admixed Compound 38 from the cryoground polymer. This suggests that the polypropylene would release active PACPeD catalyst at the plastic-human body tissue interface where it would serve to reduce inflammation. Other polymers which melt under 300°C and which would be suitable for use in the above process (with any appropriate temperature changes) are polyethylene, polyethylene terephthalate, and polyamides. EXAMPLE 21 IN VIVO EVALUATION OF THE INFLAMMATORY RESPONSE TO SEVERAL SURFACE COVALENTLY CONJUGATED POLYMERS AND METAL Samples of biomaterials, with and without PACPeD catalysts, in the form of 5 - 6 mm discs were implanted subcutaneously on the dorsal surface of female, 250 - 300 gm, Sprague Dawley rats. All disks were sterilized by three brief rinses in 70% alcohol followed by five brief rinses in sterile saline (0.9% NaCl) just prior to implantation. All biomaterials were conjugated with Compound 43. Polyurethane implants were bathed in sterile saline for one hour prior to sterilization in ethanol and implantation. Animals were initially anesthetized with 5% oxygen and 95% carbon dioxide to shave the dorsal region followed by methefane vapor administered through a nose cone during surgery. Following a sterile scrub of the surgical field, a 5 to 6 cm incision through the skin was made along the dorsal midline, a pocket in the interstitial fascia was prepared with a blunt scissors and the implant disks were inserted. The wound was closed with surgical staples. All animals were ambulatory within one hour of anesthesia. For the polyurethane and polyethylene study, each animal received an untreated control and two PACPeD treated disks at a high and low dose. For the tantalum study, each animal received a total of four disks, two controls containing to two types of linkers and two matched PACPeD treated discs. After periods of 3, 7, 14, and 28 days, animals were sacrificed with 100% carbon dioxide and the dorsal skin flap was removed and fixed in 10% neutral buffered formalin. The skin tissue was pinned upside down for photography of the implants in situ and the individual implants with surrounding tissue were excised and processed in paraffin for light microscopy. PE and PEUU implants were sectioned with the implants embedded in the paraffin block. Tantalum implants were embedded in paraffin and the paraffin block was cut in half with a low speed diamond saw. These halves were then cooled in liquid nitrogen and fractured with a cold razor blade to expose the tantalum disc. The disc was then removed from the block leaving the implant capsule intact. The tissue blocks were remelted and mounted to expose the implant capsule for microtomy. Sections were stained with hematoxylin and eosin and Gomori trichrome (Sigma, St. Louis MO) . In addition, sections were stained immunohistochemically to identify monocyte-derived macrophages with a macrophage specific antibody, EDI (Chemicon Inc., Temecula, CA) . The cellular composition of the implant capsule and surrounding tissue and the matrix composition were scored visually. Measurements of foreign body giant cells number and capsule thickness were made by visual inspection and by computer based measurement of digital micrographs. All data were reported as the mean and standard deviation. Results Conjugated Polyethylene Histological analysis was performed on triplicate sets of untreated control PE disks and two PACPeD treated PE disks having with either a low (0.06 %) or high (1.1 % (w/w)) level of PACPeD after 3, 7, 14 and 28 days of implantation. These times were selected in order to observe the acute inflammation phase and the progression to a chronic inflammation. Although differences in the healing response were observed at each time, major differences were apparent at 3 and 28 days. At 3 days, control PE disks were completely surrounded by a dense granulation tissue consisting of neutrophils and macrophages, Figure 5A. Small blood vessels in tissue adjacent to the implant contained many adherent monocytes and leukocytes and some in various stages of transendothelial migration from blood to implant tissue. In striking contrast, the granulation tissue surrounding low and high dose PACPeD - PE, Figures 5B and 5C, contained very few and no neutrophils, respectively. Numerous macrophages were present on the low dose implant and labeled with EDI antibody to suggest that they are monocyte derived. In the high dose implant capsule, the number of macrophages was greatly reduced and fibroblast like cells constituted the major cell type. In addition, blood vessels adjacent to the PACPeD-PE implants contained no adherent leukocytes or monocytes . After 28 days equally remarkable differences were observed. In the control, foreign body giant cells (FBGCs) formed a layer between the implant and the implant capsule tissue, Figure 6A, to indicate that chronic inflammation was underway. FBGCs also filled the many scratches that formed the rough PE surface. The implant capsule tissue consisted of layered fibroblasts, some EDI positive macrophages, a few neutrophils and collagen matrix. For the low level PACPeD disks, the capsule had a marked reduction in FBGCs on the surface and in number of cells in the capsule in comparison to control, Figure 6B . With the high PACPeD-PE disks, FBGCs were rarely observed, Figure 6C. The number of FBGCs observed in two independent sections per disk for a total of six counts per treatment group were averaged and revealed a statistically significant decrease in FBGC with PACPeD-PE over control, Figure 7. In addition, the thickness of the implant capsule as measured from the same sections was significantly reduced in comparison to untreated control PE . Polyurethane Histological analysis was performed on triplicate sets of untreated control PEUU disks and two PACPeD treated PE disks having with either a low (0.6 %) or high (3.0 % w/w) level of PACPeD after 3, 7, 14 and 28 days of implantation. Although, PEUU is well known to be less inflammatory than polyethylene, the effect of surface bound PACPeD mimic was obvious and similar to that observed for PE disks at 3 and 28 days. At 3 days, implant capsules of control PEUU disks contained neutrophils and EDI positive macrophages although their numbers were estimated to be two orders of magnitude less than PE control . Capsules surrounding the low level PACPeD - PEUU implants had a markedly reduced but detectable number of neutrophils with macrophages and fibroblast being predominant. As was observed for the PACPeD-PE implants, capsule tissue around the high dose PACPeD-PEUU disks contained no observable neutrophils and a reduced number of macrophages . At 28 days, implant capsules around the PEUU control disks had a layer of adherent FBGCs and layers of fibroblasts, EDI positive macrophages and collagen matrix, Figure 8A. With the low level PACPeD, Figure 8B, the number of FBGCs was reduced although the implant capsule contained fibroblast and fewer EDI positive macrophages and had a thickness similar to the control. The high level PACPeD-PEUU disk capsule had very few FBGCs and the capsule thickness was estimated to be one half of the control capsule, Figure 8C. It is well known that PEUU is susceptible to biodegradation in vivo leading to the formation of surface pits and cracks. To monitor this effect in control and functionalized disks, scanning electron microscopy, SEM, was used to examine non- implanted disks and 28 day implanted disks, Figures 1-3. The non-implanted PEUU film showed a smooth surface with no cracks or pitted areas, Figure 1. The implanted control PEUU sample after 28 days contained large, multiple cracks and areas where the surface had been eroded, Figure 2. The implanted PACPeD-PEUU sample showed no obvious differences compared to the non- implanted control, Figure 3. Hence, in addition to inhibiting both acute and chronic inflammatory responses, PACPeD linked to PEUU surface inhibited surface degradation observed at 28 days. Tantalum Tantalum disks treated with either the silane linker or the PACPeD and silane linker were implanted for 3 and 28 days. The healing response was similar to that seen for treated and untreated polymers. After 3 days, a neutrophil rich granulation tissue enveloped the Ta- silane linker treated disk, figure 9A. With PACPeD treatment, the neutrophils were absent with macrophages and matrix making up the bulk of the implant bed, figure 9B. After 28 days the control disks had a more pronounced implant capsule which was reduced in thickness at PACPeD treated disks, Figure 10. EXAMPLE 22 IN VIVO EVALUATION OF THE INFLAMMATORY RESPONSE TO POLYPROPYLENE ADMIXED WITH COMPOUND 54 Sample Fiber Preparation The polypropylene implants for the rat studies were made in a fiber form. After a dry blend was made in the cryo-grinder, the mixture was subjected to twin screw mixing in a DACA melt mixer. 3 gms of PP and 60 mg of Compound 54 (more lipophilic than Compound 38) was used. The impact time in the cryogrinder was 5 minutes. The melt mixing chamber was held at 250°C. The mixing time was 5 minutes with the rpm being 50. No appreciable differences in the torque was seen between the control and the Compound 54 incorporated PP . A 50 denier fiber with 30% of elongation to break was the target. The parameters in the DACA melt spin equipment were the following: Diameter of the spinneret : 0.5 mm Piston speed: 9.82 mm/min Spin speed of the main godet : 1 2.85 RPM Draw ratio: 7 Temperature of the plate: 125°C Temperature of the barrel: 250 °C The extruded strands from the melt blending were cut into little pieces which fed into the barrel more easily. The melt spinning was done at 250°C. Because the medical grade polymer degrades after 20 minutes at high temperature we had to use a flow rate of 0.35g/min (the amount of PP in the barrel is 7g) . Implantation Procedure Polypropylene fibers, with and without Compound 54 mimic, were implanted subdermally in 250 - 300 gram female rats. The polypropylene fiber implant consisted of a 15 to 20 cm length that was wrapped and tied into a figure eight shape measuring about 2 cm by 0.5. Animals were anesthetized with a mixture of 50/10 mg/kg Ketamine/Xylazine by intraperitoneal injection. The right flank was shaved and scrubbed with surgical scrub. A small 1.5 cm long incision was made over the right haunch. A subcutaneous pocket was made and the appropriate piece of material was placed in the pocket. The implants were briefly rinsed in 70% alcohol and rinsed with 2 dips in sterile saline prior to insertion into the tissue pocket. The incision was closed with a stainless steel staple. The rats were returned to their cages for recovery. The animal were removed from their cages after 21 days post implant and sacrificed by C0 2 inhalation. The implants were removed with overlying skin attached and fixed in Streck STF fixative overnight at 4-3°C. The explants were cut into two or three pieces to expose polymer cross-sections and were processed for embedding in paraffin. Routine sections were cut and stained with hematoxylin and eosin or Masson Trichrome and immunostained with an antibody specific of macrophages, EDI (Chemicon Inc.) . In Vivo Response to Implanted Compound 54 Containing Polypropylene Gross histology examination of control PP fibers attached to the under surface of the skin flap explants evidenced the fibers to be surrounded by a relatively thick matrix of collagen. The position and overall shape of the implant were discernible but individual fibers could not be seen. Histological cross-sections confirmed a relatively thick wrap of connective tissue. In addition to matrix, higher magnification views reveal an intense inflammatory reaction at each fiber. Control fibers cover with one to two layers of cells which appear to be macrophages based on positive immunohistochemical staining with the rate macrophage marker, EDI, Figure 4A. In addition, foreign body giant cells were also present on all control fibers. These observations are consistent with the expected chronic inflammatory response. Compound 54 containing PP fibers exhibited a different response. Gross examination reveal an implant site in which the individual fibers were clearly visible. It was obvious that the fibrotic and cellular response which covered the control PP fibers was reduced. Histologically, a reduced fibrotic response was apparent, with only a thin wrap of matrix being observed in Trichrome stained sections. In addition, the inflammatory response at individual SODm containing fibers was markedly reduced. Typically, modified fibers were covered by a thin layer of matrix and few fibroblasts and only partial coverage by macrophages, Figure 4B. Foreign body giant cells were seldom observed on modified fibers. A count of foreign body giant cells per fiber were performed on control and Compound 54 containing PP fibers. Control fiber FBGC counts were 2.63 ± 1.34 per fiber, n = 20 while modified fibers had 1.28 ± 1.04 FBGC per fiber, n = 40. Despite the striking difference in the inflammatory response, the number or density of fine capillaries appeared to be very similar between the control and modified fibers. This was assessed visually in tissues spaces between the fibers within the hank and the tissue surrounding the hank implant . EXAMPLE 23 LUMINOL ANALYSIS OF MODIFIED POLYMERS AND METALS TO DETERMINE SUPEROXIDE DISMUTATING ACTIVITY The Michelson assay uses xanthine oxidase and hypoxanthine to produce superoxide radical anion in situ in a steady-state manner. If not eliminated from the solution with an antioxidant, superoxide then reacts with luminol to produce a measurable amount of light. This reaction is stoichiometric and provides a linear response under pseudo first-order reaction conditions (i.e. [luminol] >> [02-] ) . The light emission is measured over several minutes 9as the enzyme-substrate solution produces superoxide at a specific rate) and the integration of units over that time is reported. It should then be possible to take samples of antioxidants and determine the presence of catalyst, the rate of dismutation, and/or whether the compound is actually catalytic or stoichiometric in its ability to dismute superoxide. Using this method, we have taken sample films 1 (lactide/ glycolide polymer) doped with Compound 38, a known catalyst for the dismutation of superoxide and the parent compound in our current SAR, and analyzed them on a Turner Designs TD-20/20 Luminometer X 400uL of a 0.05 unit/mL xanthine oxidase, 0.1 mM EDTA and 0.1 mM Luminol in 0.1 M glycine buffer at pH 9; 200uL of a 250 uM ^ ■ Michelson, A.M. In Handbook of Methods for Oxygen Radical Research, Greenwald, R.A. , Ed.; CRC:Boca Raton, 1989; p. 74. 2 Gary W. Franklin; Monsanto Notebook, p. 6136376, unpublished results. xanthine solution are added via autoinjector to a one 2 square millimeter sample of each film in the sample well . The sample is then run on the Luminometer, and the reading translated into an integration. Samples of PEUU surface covalently conjugated with Compound 43 were tested and found to possess superoxide dismutating activity. EXAMPLE 24 STOPPED-FLOW KINETIC ANALYSIS Stopped-flow kinetic analysis has been utilized to determine whether a compound can catalyze the dismutation of superoxide (Riley, D. P., Rivers, W. J. and Weiss, R. H., "Stopped-Flow Kinetic Analysis for Monitoring Superoxide Decay in Aqueous Systems," Anal. Biochem, 196: 344-349 1991) . For the attainment of consistent and accurate measurements all reagents were biologically clean and metal -free. To achieve this, all buffers (Calbiochem) were biological grade, metal-free buffers and were handled with utensils which had been washed first with 0. IN HCl, followed by purified water, followed by a rinse in a 10 "4 M EDTA bath at pH 8, followed by a rinse with purified water and dried at 65. degree. C. for several hours. Dry DMSO solutions of potassium superoxide (Aldrich) were prepared under a dry, inert atmosphere of argon in a Vacuum Atmospheres dry glovebox using dried glassware. The DMSO solutions were prepared immediately before every stopped-flow experiment. A mortar and pestle were used to grind the yellow solid potassium superoxide (.about.100 mg) . The powder was then ground with a few drops of DMSO and the slurry transferred to a flask containing an additional 25 ml of DMSO. The resultant slurry was stirred for 1/2 h and then filtered. This procedure gave reproducibly .about.2 mM concentrations of superoxide in DMSO. These solutions were transferred to a glovebag under nitrogen in sealed vials prior to loading the syringe under nitrogen. It should be noted that the DMSO/superoxide solutions are extremely sensitive to water, heat, air, and extraneous metals. A fresh, pure solution has a very slight yellowish tint. Water for buffer solutions was delivered from an in-house deionized water system to a Barnstead Nanopure Ultrapure Series 550 water system and then double distilled, first from alkaline potassium permanganate and then from a dilute EDTA solution. For example, a solution containing 1.0 g of potassium permanganate, 2 liters of water and additional sodium hydroxide necessary to bring the pH to 9.0 were added to a 2-liter flask fitted with a solvent distillation head. This distillation will oxidize any trace of organic compounds in the water. The final distillation was carried out under nitrogen in a 2.5-liter flask containing 1500 ml of water from the first still and 1.0 x 10 '6 M EDTA. This step will remove remaining trace metals from the ultrapure water. To prevent EDTA mist from volatilizing over the reflux arm to the still head, the 40-cm vertical arm was packed with glass beads and wrapped with insulation. This system produces deoxygenated water that can be measured to have a conductivity of less than 2.0 nanomhos/cm 2 . The stopped- flow spectrometer system was designed and manufactured by Kinetic Instruments Inc. (Ann Arbor, Mich.) and was interfaced to a MAC IICX personal computer. The software for the stopped-flow analysis was provided by Kinetics Instrument Inc. and was written in QuickBasic with MacAdios drivers. Typical injector volumes (0.10 ml of buffer and 0.006 ml of DMSO) were calibrated so that a large excess of water over the DMSO solution were mixed together. The actual ratio was approximately 19/1 so that the initial concentration of superoxide in the aqueous solution was in the range 60-120 μM. Since the published extinction coefficient of superoxide in H 2 0 at 245 nm is . about .2250M "1 cm "1 (1), an initial absorbance value of approximately 0.3-0.5 would be expected for a 2 -cm path length cell, and this was observed experimentally. Aqueous solutions to be mixed with the DMSO solution of superoxide were prepared using 80 mM concentrations of the Hepes buffer, pH 8.1 (free acid+Na form) . One of the reservoir syringes was filled with 5 ml of the DMSO solution while the other was filled with 5 ml of the aqueous buffer solution. The entire injection block, mixer, and spectrometer cell were immersed in a thermostated circulating water bath with a temperature of 21°C ± 0.5°C. Prior to initiating data collection for a superoxide decay, a baseline average was obtained by injecting several shots of the buffer and DMSO solutions into the mixing chamber. These shots were averaged and stored as the baseline. The first shots to be collected during a series of runs were with aqueous solutions that did not contain catalyst. This assures that each series of trials were free of contamination capable of generating first-order superoxide decay profiles. If the decays observed for several shots of the buffer solution were second-order, solutions of manganese (II) complexes could be utilized. In general, the potential SOD catalyst was screened over a wide range of concentrations. Since the initial concentration of superoxide upon mixing the DMSO with the aqueous buffer was about 1.2 times 10 "4 M, we wanted to use a manganese (II) complex concentration that was at least 20 times less than the substrate superoxide. Consequently, we generally screened compounds for superoxide dismutating activity using concentrations ranging from 5 x 10 "7 to 8 x 10 "6 M. Data acquired from the experiment was imported into a suitable math program (e.g., Cricket Graph) so that standard kinetic data analyses could be performed. Catalytic rate constants for dismutation of superoxide by manganese (II) complexes were determined from linear plots of observed rate constants (k obs ) versus the concentration of the manganese (II) complexes. k obs values were obtained from linear plots of In absorbance at 245 nm versus time for the dismutation of superoxide by the manganese (II) complexes . EXAMPLE 25 USE OF HYALURONIC ACID ESTERS SURFACE COVALENTLY CONJUGATED WITH COMPOUND 43 TO PRODUCE A NEURAL GROWTH GUIDE CHANNEL DEVICE A guide channel with a composite thread/polymeric matrix structure wherein the thread comprises HYAFF 11 (total benzyl ester of HY, 100% esterified) and the matrix is composed of HYAFF llp75 (benzyl ester of HY 75% esterified) is obtained by the following procedure. A. Preparation of Esters Preparation of the Benzyl Ester of Hyaluronic Acid (HY) : 3 g of the potassium salt of HY with a molecular weight of 162,000 are suspended in 200 ml of dimethylsulfoxide; 120 mg of tetrabutylammonium iodide and 2.4 g of benzyl bromide are added. The suspension is kept in agitation for 48 hours at 30° C. The resulting mixture is slowly poured into 1,000 ml of ethyl acetate under constant agitation. A precipitate is formed which is filtered and washed four times with 150 ml of ethyl acetate and finally vacuum dried for twenty four hours at 30° C. 3.1 g of the benzyl ester product in the title are obtained. Quantitative determination of the ester groups is carried out according to the method described on pages 169-172 of Siggia S. and Hanna J. G. "Quantitative organic Analysis Via Functional Groups," 4th Edition, John Wiley and Sons. Preparation of the (Partial) Benzyl Ester of Hyaluronic Acid (HY) -75% Esterified Carboxylic Groups, -25 % Salified Carboxylic Groups (Na) : 12.4 g of HY tetrabutylammonium salt with a molecular weight of 170,000, corresponding to 20 m.Eq. of a monomeric unit, are solubilized in 620 ml of dimethylsulfoxide at 25° C. 120 mg of tetrabutylammonium iodide and 15.0 m.Eq. of benzyl bromide are added and the resulting solution is kept at a temperature of 30° for 12 hours. A solution containing 62 ml of water and 9 g of sodium chloride is added and the resulting mixture is slowly poured into 3,500 ml of acetone under constant agitation. A precipitate is formed which is filtered and washed three times with 500 ml of acetone/water, 5:1, and three times with acetone, and finally vacuum dried for eight hours at 30° C. The product is then dissolved in 550 ml of water containing 1% sodium chloride and the solution is slowly poured into 3,000 ml of acetone under constant agitation. A precipitate is formed which is filtered and washed twice with 500 ml of acetone/water, 5:1, three times with 500 ml of acetone, and finally vacuum dried for 24 hours at 30° C. 7.9 g of the partial propyl ester compound in the title are obtained. Quantitative determination of the ester groups is carried out using the method of R. H. Cundiff and P. C. Markunas Anal. Chem. 33, 1028-1030, (1961) . The HYAFP esters are then surface covalently conjugated with Compound 43 as in Example 14. B. Production of the Device A thread of total HYAFP 11 esters, 250 denier, with a minimum tensile strength at break of 1.5 gr/denier and 19% elongation is entwined around an electropolished AISI 316 steel bar with an outer diameter of 1.5 mm, which is the desired inner diameter of the composite guide channel. The woven product is obtained using a machine with 16 loaders per operative part. A typical tube-weaving system system (like the one shown in U.S. Pat. No. 5,879,359) comprising the steel bar with a threaded tube fitted over it is placed in position. The apparatus is rotated at a speed of 115 rpm. A quantity of HYAFF llp75/dimethylsulfoxide solution at a concentration of 135 mg/ml is spread over the rotating system. The excess solution is removed with a spatula, and the system is removed from the apparatus and immersed in absolute ethanol. After coagulation, the juide channel is removed from the steel bar and cut to size. The channel made by the above technique is 20 mm long, 300 .mu.m thick, has an internal diameter of 1.5 mm, and has a weight of 40 mg, equal to 20 mg/cm. EXAMPLE 26 USE OF METALS SURFACE COVALENTLY CONJUGATED WITH COMPOUND 43 TO PRODUCE A STENT A stent may be formed from surgical stainless steel alloy wire which is bent into a zigzag pattern, and then wound around a central axis in a helical pattern. Referring now more particularly to Figures 11-17, there is illustrated in FIG. 11 a midpoint in the construction of the stent which comprises the preferred embodiment of the present invention. FIG. 11 shows a wire bent into an elongated zigzag pattern 5 having a plurality of substantially straight wire sections 9-15 of various lengths separated by a plurality of bends 8. The wire has first and second ends designated as 6 and 7, respectively. Zigzag pattern 5 is preferably formed from a single strand of stainless steel wire having a diameter in the range of 0.005 to 0.025 inch. FIG. 13 shows a completed stent 30. The construction of the stent is completed by helically winding elongated zigzag pattern 5 about a central axis 31. Zigzag pattern 5 is wound in such a way that a majority of the bends 8 are distributed in a helix along the length of the stent 30. There are preferably about twelve interconnected bends in each revolution of the helix, or six adjacent bends of the zigzag pattern in each revolution. The construction of stent 30 is completed by interconnecting adjacent bends of the helix with a filament 32, preferably a nylon monofilament suture. Filament 32 acts as a limit means to prevent the stent from further radial expansion beyond the tubular shape shown in FIGS. 13 and 14. The tubular shape has a central axis 31, a first end 33 and a second end 35. Each end of stent 30 is defined by a plurality of end bends 36, which are themselves interconnected with a filament 34. Other embodiments of the present invention are contemplated in which the end bends 36 are left unconnected in the finished stent. FIG. 14 shows an end view of stent 30 further revealing its tubular shape. FIG. 15 shows stent 30 of FIG. 13 when radially compressed about central axis 31 such that the straight wire sections and the bends are tightly packed around central axis 31. Referring back to FIG. 11, the zigzag pattern is made up of straight wire sections having various lengths which are distributed in a certain pattern to better facilitate the helical structure of the final stent construction. For instance, in one embodiment, end wire sections 9 could be made to a length of 9 mm followed by two wire sections 11 each being 11 mm in length. Wire sections 11 are followed by two 13 mm wire sections 13, which are in turn followed by two wire sections 15 having a length of 15 mm. Sections 15 are followed by a single wire section 17 having a length of 17 mm. These gradually increasing wire sections at either end of the zigzag pattern enable the final stent to have well defined square ends. In other words, the gradually increasing length wire sections on either end of the zigzag pattern enable the final stent to have a tubular shape in which the ends of the tube are substantially perpendicular to the central axis of the stent. Following wire section 17, there are a plurality of alternating length sections 13 and 15. Short sections 13 being 13 mm in length and long sections 15 being 15 mm in length. This alternating sequence is continued for whatever distance is desired to correspond to the desired length of the final stent. The difference in length between the short sections 13 and long sections 15 is primarily dependent upon the desired slope of the helix (see .beta, in FIG. 16) and the desired number of bends in each revolution of the helix. FIG. 16 is an enlarged view of a portion of the stent shown in FIG. 13. The body of stent 30 includes a series of alternating short and long sections, 13 and 15 respectively. A bend 8 connects each pair of short and long sections 13 and 15. Each bend 8 defines an angle 2α which can be bisected by a bisector 40. These short and long sections are arranged in such a way that bisector 40 is parallel to the central axis 31 of the stent. This allows the stent to be radially compressed without unnecessary distortion. FIG. 12 shows an enlarged view of one end of the zigzag pattern. End 6 of the wire is bent to form a closed eye portion 20. Eye 20 is preferably kept closed by the application of the small amount of solder to the end 6 of the wire after it has been bent into a small loop. Each of the bends 8 of the zigzag pattern are bent to include a small eye portion designated as 21 and 23 in FIG. 12, respectively. Eye 21 includes a small amount of solder 22 which renders eye 21 closed. Eye 23 includes no solder and is left open. The bends 8 which define the helix can be either in the form of a closed eye, as in eye 21, or open as in eye 23. After forming the stent, the stent is then modified by surface covalent conjugation with a silyl linker, as in Example 13. By treatment with acid mixtures well known in the art, the stainless steel surface can be oxidized to display a layer of hydroxide. The conjugation then proceeds as in Example 13. EXAMPLE 27 USE OF SURFACE COVALENTLY CONJUGATED PET FIBERS TO PRODUCE A WOVEN VASCULAR GRAFT PET fibers are surface covalently conjugated with Compound 43 according to Example 7. The vascular graft fabric is formed from single ply, 50 denier, 47 filament (1/50/47) pretexturized, high shrinkage (in excess of approximately 15%) , polyethylene terephthalate (PET) yarns woven in a plain weave pattern with 83 ends/inch and 132 picks/inch (prior to processing) . The vascular graft fabric, prior to processing, has a double wall size of less than 0.02 inches and preferably has a double wall thickness of about 0.01 inches. The yarns may be twisted prior to weaving and a graft with 8 twists per inch has provided acceptable properties. Other weave patterns, yarn sizes (including microdenier) and thread counts also are contemplated so long as the resulting fabric has the desired thinness, radial compliance and resistance to long term radial dilation and longitudinal expansion. The woven fabric is washed at an appropriate temperature, such as between 60°-90° C, and then is steam set over a mandrel to provide the desired tubular configuration. The graft is then dried in an oven or in a conventional dryer at approximately 150° F. Any of the washing, steaming and drying temperatures may be adjusted to affect the amount of shrinkage of the fabric yarns. In this manner, the prosthetic is radially compliant to the extent necessary for the ends of the graft to conform to the slightly larger anchoring sections of the aorta, but resists radial dilation that otherwise could lead to rupture of the aneurysm and axial extension that could block the entrance to an iliac artery. Radial dilation is considered to occur when a graft expands a further 5% after radial compliance. The 5% window allows for slight radial expansion due to the inherent stretch in the yarn of the fabric . The thin walled, woven vascular graft fabric is be formed into a tubular configuration and collapsed into a reduced profile for percutaneous delivery of the prosthetic to the delivery site. The implant is sufficiently resilient so that it will revert back to its normal, expanded shape upon deployment either naturally or under the influence of resilient anchors that secure the implant to the vessel wall, and or, alternatively, struts that prevent compression and twisting of the implant. The thin wall structure allows small delivery instruments (18 Fr or smaller) to be employed when the graft is percutaneously placed. The fine wall thickness also is believed to facilitate the healing process. The graft, when used for the repair of an abdominal aortic aneurysm, may be provided in a variety of outer diameters and lengths to match the normal range of aortic dimensions . The biologically compatible prosthetic fabric encourages tissue ingrowth and the formation of a neointima lining along the interior surface of the graft, preventing clotting of blood within the lumen of the prosthetic which could occlude the graft . The graft has sufficient strength to maintain the patency of the vessel lumen and sufficient burst resistance to conduct blood flow at the pressures encountered in the aorta without rupturing. The graft is usually preclotted with either the patient's own blood or by coating the rabric with an impervious material such as albumin, collagen or gelatin to prevent hemorrhaging as blood initially flows through the graft. Although a constant diameter graft is preferred, a varying dimensioned prosthetic also is contemplated. The graft is also usually provided with one or more radiopaque stripes to facilitate fluoroscopic or X-ray observation of the graft. EXAMPLE 28 USE OF COPOLYMERIZED POLYURETHANE TO TO INSULATE CARDIAC SIMULATOR LEAD WIRE A die-clad composite conductor is made with a highly conducting core and a cladding layer. Copper and copper alloys are particularly suitable for the core material of the composite conductor. Pure copper is preferable, but alloys such as Cu0.15Zr, Cu4Ti, Cu2Be, Cul.7Be, Cu0.7Be, Cu28Zn, Cu37Zn, Cu6Sn, Cu8Sn and Cu2Fe may be used. A metal selected from the group consisting of tantalum, titanium, zirconium, niobium, titanium-base alloys, platinum, platinum- iridium alloys, platinum-palladium alloys and platinum-rhodium alloys is applied as a cladding layer to the conducting core by drawing through a die. The cladding layer thickness is between 0.0025 and 0.035 mm, while the core diameter is between 0.04 and 0.03 mm. Although a single strand conductor could be used, the risks of breakage are reduced and the conductivity is increased without going beyond the above described preferred ranges for core diameter and cladding if a stranded conductor is used. Furthermore a stranded conductor provides increased flexibility. Thus, it is preferred that the conductor in the cable be composed of two or more thinner strands twisted together. The clad wire conductor is enclosed in an elastic covering tube, which consists of a synthetic elastomer such as flexible polyurethane. A polyurethane which has been copolymerized with a PACPeD catalyst, such as the polyurethane of Example 12, should be used. It is sufficiently elastic and flexible to make possible its introduction into the heart chamber simply by being carried along through the blood stream. The biocompatability of the clad wire conductor of the cable is improved by oxidizing the surface of the clad wire and covalently conjugating a PACPeD catalyst to the wire, as in Example 13.
