Abstract: A metal ionic antimicrobial surface configured for external use on a surface location in an indoor environment. A surface structure includes a pair of opposed major surfaces, one surface forming an exposed layer having a pattern of conductive strips and corresponding insulative spacings with a power pod structure secured to the surface structure. The power pod structure houses a battery and a power control circuit electrically connected to the conductive strips. In embodiments, the battery has an amp-hour capacity of 150-1500 mAh, an average width of each conductive strip of copper and silver metallic ions and each insulative spacing is between 0.1 to 0.5 millimeters, and the power control circuit includes a voltage booster circuit that maintains a constant low voltage of 2.5V-4.5V.

Abstract: A method and device for destroying and inhibiting exposure to microbes and infection includes a first element and a second element, and a power source. At least one of the elements includes antimicrobial metal, which, when energized by the power source, produces ions that are lethal to microbes. The device can be incorporated into virtually any useful object. During normal use of the object, electrical communication is established between the two elements, causing current supplied from the power source to flow through the antimicrobial metal. The two elements are configured and arranged to ensure that ions flowing from the antimicrobial metal flow through the region in which it is desired to kill microbes. The antimicrobial metal can be on the surface of the element, incorporated into the material making up the element, or provided in any other way that allows the antimicrobial effect to be achieved.

Abstract: A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.
