Abstract
An implant having a base body, comprised either entirely or in part of a biocorrodible metallic material wherein at least the parts of the base body having the biocorrodible metallic material are at least partially covered with a coating of a crosslinked CFx layer that is nonpolymerized and has an F/C ratio in the range of 0.5 to 1.5.
Claims7
An implant, comprising:
- a base body comprising a biocorrodible metallic material wherein at least the parts of the base body comprising the biocorrodible metallic material are at least partially covered with a coating of a crosslinked carbon fluoride material having the general formula CFx and selected from the group consisting of fluoroalkanes of the formula CnF2n+2, fluoroalkenes of the formula CnF2n, fluoroalkynes of the formula CnF2n−2 and cyclic fluorocarbons, where the carbon fluoride material has between 3 and 10 carbon atoms and where n=2-10, wherein x is the ratio of F atoms to C atoms and is between 0.5 and 1.5, wherein the crosslinked carbon fluoride material is nonpolymerized, and wherein the amount of coating allows for controlled corrosion of the biocorrodible metallic material.
