Abstract
A percutaneous implant device includes a structure for storing a bioreactive agent such as an antimicrobic agent, an anti-inflammatory drug, a growth hormone, and an antifungal drug. The structure can take the form of a container or a solid solution. The percutaneous device has a conduit, and the structure containing the bioreactive agent is disposed under the skin and around the conduit in the vicinity where the conduit passes through the skin of the living host. The structure containing the bioreactive agent is refillable via either a wall which is penetrable and reseals after penetration, or an access opening which can be opened or closed and is accessible from outside the living host. The container can include a wall having a diffusion coefficient which increases the rate of diffusion with increasing local temperature.
