Abstract
Implantable ports and other devices are disinfected by the injection of an anti-microbial agent into a tissue pocket surrounding the device. In a first embodiment, the anti-microbial agent is injected through an aperture in the device to flush internal regions of the device before infusing the tissue pocket. In other embodiments, the anti-microbial agent is injected directly to a target site on the exterior of the device. Implantable devices may include special, usually hardened, target regions for receiving the sharpened end of a needle used to inject the anti-microbial agent.
