Abstract: A composition composed of a persulfate, boric acid, a fluorine containing acid and an inorganic acid. Adjuvants also may be included in the composition. The composition may be employed as a microetch solution in the fabrication of microelectronic packages.

Abstract: There is disclosed a medical device for implantation that acts to prevent transmission of infectious agents. Specifically, the present invention provides implantable devices, such as catheters or living skin matrices or wound dressings, for insertion into various body cavities or over wound sites to confer to the site microbicidal or virucidal activity. Devices in the disclosure designed as vaginal inserts also exhibit contraceptive spermicidal activity. The coated devices or devices having the inventive polymeric material interspersed throughout are formed into appropriate shapes according to their contemplated uses (such as catheters or Foley catheters). Further, the present invention provides devices for providing therapeutic anti-microbial activity into an infected body cavity or on an infected wound site.

Abstract: Methods of providing anti-infective activity to a medical device including the steps of exposing the medical device to an anti-infective oxidant, and transferring the anti-infective oxidant into a wall of the medical device. One embodiment includes the step of exposing a medical device that is at least in part within a patient to the anti-infective oxidant. Another embodiment includes the steps of exposing a medical device to an aqueous solution which produces the anti-infective oxidant and transferring a sufficient amount of the anti-infective oxidant into the medical device wall to provide the medical device with anti-infective activity. Also provided is an oxidant releasing member that has anti-infective oxidant releasably contained therein and that is configured to be disposed adjacent to the medical device.
