Estimating the term…
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.
A method for inhibiting infection of an implanted device, said method comprising percutaneously injecting a washing solution to the device in an amount sufficient to flush a region within or surrounding the device.
A method for inhibiting infection of an implanted port which has an aperture for receiving an access tube, said method comprising subcutaneously injecting a washing solution into the aperture in an amount sufficient to at least partly fill said aperture and to overflow from said aperture to infuse a region surrounding the port within a pocket of tissue.
A system for cleansing and accessing an implanted port, said system comprising:
The use of a washing solution for the cleansing of a subcutaneously implanted device, wherein the washing solution is percutaneously injected into or around the device.
