Abstract
An anti-microbial component of the IMD that is exposed to body fluids in the pocket is compounded of an anti-microbial metal ion zeolite that elutes metal ions in concentrations exhibiting anti-microbial activity over a substantial period of time of implantation is disclosed. The anti-microbial component is physically attached to the IMD to be retained in close proximity and in a stable location in the subcutaneous pocket. In another embodiment, the anti-microbial component conforms to the shape of the IMD and is attachable to and detachable from the IMD. In another embodiment, the polymeric component includes a connector header of an IPG or a monitor, or a connector sleeve or the sealing rings of a proximal connector assembly of an electrical medical lead coupled with an IPG or monitor that are located in the subcutaneous pocket or in the backing of a subcutaneously implanted cardioversion/defibrillation (C/D) electrode.
