Bone implant and systems that controllably releases silver

An implant for providing antimicrobial treatment to a bone, tissue or organ, the implant comprising:

• an elongate body having a threaded outer screw region and a sharp distal end;
• a first coating forming a band around the threaded outer screw region of one or more of platinum, palladium and gold;
• and
• a second coating of one or more of silver, zinc, or silver and zinc, wherein the second coating contacts the first coating and is configured to corrode when the implant is inserted into the bone, tissue or organ and galvanically release one or more of silver, zinc or silver and zinc as the second coating is corroded in the presence of an electrolytic solution;
• a treatment cartridge configured to engage an inner chamber within the elongate body, wherein the second coating is on the treatment cartridge, wherein the treatment cartridge comprises a guide to aid in aligning the treatment cartridge within the elongate body.

An implant for providing antimicrobial treatment to a bone, tissue or organ, the implant comprising:

• an elongate body having a threaded outer screw region;
• an inner channel within the elongate body;
• a plurality of exit channels extending from the inner channel and out through the elongate body;
• and
• a treatment cartridge configured to mate with the inner channel and comprising a plurality release members, each release member configured to extend from the cartridge body out through an exit channel and to galvanically release silver, zinc, or silver and zinc, wherein the treatment cartridge comprises a guide to aid in aligning the treatment cartridge within the elongate body.
