摘要:
The invention relates to a method for producing corrosion-inhibiting coatings on an implant made of a biocorrodible magnesium alloy and to implants obtained or obtainable according to the method.
摘要:
An implant is proposed, in particular made from a base material including a biodegradable metal and/or a biodegradable metal alloy, wherein the implant includes a coating made of crystalline calcium phosphate and/or amorphous calcium phosphate.
摘要:
The invention relates to an implantation device for stents, which device has hair-like extensions on at least one part of the outwardly-facing surface of that section of the device, which section is provided to attach or crimp on the stent to be implanted, wherein the mean diameter D, the mean length L, and the averaged center-to-center distance P of the hair-like extensions relative to each other are selected such that a stent is affixable on the surface covered with hair-like extensions essentially by means of van der Waals forces.
摘要:
The invention relates to an implant having a base body, consisting completely or partially of a biocorrodible metallic material, such that it decomposes in an aqueous environment to form an alkaline product, and the base body has a coating or a cavity filling, comprising a polymer matrix and at least one drug embedded in the polymer matrix, characterized in that at least one polymer of the matrix and the at least one drug are coordinated so that the drug elution rate from the matrix is increased with an increase in pH.
摘要:
A stent having a coating comprising either L-3,4-dihydroxyphenylalanine (L-DOPA) or a derivative of L-3,4-dihydroxyphenylalanine (L-DOPA), the foregoing obtained by either ionic or covalent bonding of a pharmaceutical active ingredient to either the amino or the acid function of L-3,4-dihydroxyphenylalanine (L-DOPA).
摘要:
A stent comprising a basic stent body, at least one anchor group on the surface of the basic stent body, and at least one biomolecule which is bound to the at least one anchor group, the anchor group being the same or different and selected from the group of compounds with the general formula (I) (R2O)2(O)P-L-(CH2)x-M-R1 (I) in which R1 represents —COOH, —OH, —SH, —NH2, benzophenone or benzophenone derivatives, R2 represents hydrogen, —CH2CH3 or —CH3, L represents a single bond or —O—, M represents a single bond or —(CH2—CH2—O)y, x represents an integer from 1 to 25, y represents an integer from 1 to 25 and the biomolecule or biomolecules are selected as the same or different from the group consisting of compounds which promote the attachment of the endothelial progenitor cells to the stent surface.
摘要:
A biodegradable metal stent having delayed degradation after implantation, the stent comprising a stent material coated with at least one wax material, Also provided is a method for manufacturing and use of such a stent.
摘要:
The invention relates to a balloon catheter featuring—at least on portions of the outward-turned surface of the dilatable area—hair-like extensions, with the average diameter D, the average length L, and the average center-to-center distance P of the hair-like extensions to each other being selected such that a drug on the balloon surface covered with hair-like extensions can essentially be secured by means of capillary forces.
