Abstract
A system for preventing corrosion and/or fouling of a surface of a biomedical device in contact with a corrosive environment comprising: (a) a semiconductive coating in conductive contact with at least part of the surface; and (b) an electronic filter for filtering corrosive noise and a method of preventing corrosion and/or fouling using the system.
Claims96
A method for preventing corrosion of a conductive surface of a biomedical device in contact with a corrosive environment, said method comprising:
- (a) coating the conductive surface with a semiconductive coating and providing an electronic filter connected to the coated conductive structure;
- (b) monitoring corrosive noise generated by the coated conductive structure and adjusting filter properties of said electronic filter to minimize the corrosive noise, wherein said conductive surface is a surface of a biomedical device selected from the group consisting of artificial joints, and organs.
A system for preventing corrosion or fouling or both of a biomedical device, comprising:
- (a) a biomedical device having thereon a semiconductive coating, wherein said biomedical device is a member selected from the group consisting of artificial joints, and organs;
- (b) a fixed electronic filter;
- (c) a corrosive noise monitoring system;
- and
- (d) an adjustable filter.
