Abstract
Implantable ports and other devices are cleansed by the injection of a washing solution into a region in the device or in a tissue pocket surrounding the device. In a first embodiment, the washing solution is injected through an aperture in the device to flush internal regions of the device before infusing the tissue pocket and flushing outwardly through a tissue tract leading to the device. In other embodiments, the washing solution 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 washing solution. Kits will include devices, syringes, access devices, and instructions for cleansing according to the methods of the present invention.
