<p>In combination with a device (20) adapted for at least partial implantation in a living body to perform a function with respect to that body such as introducing a material into the body, relieving the body of a material, monitoring a condition within the body, or introducing electrical stimulus into the body, servicing means (26) are provided in association with the device for maintaining the device in effective operating condition. The device and servicing means may be arranged in a single housing such that a portion of the device extends from the housing into operable position in the body, in separate but operably connected housings, or the servicing means may be split between the device and a separate housing. The actual servicing of the device may be done within a service housing where the portion of the device to be serviced is drawn into the service housing and mechanically or chemically serviced, the servicing instrumentality may be moved from a service housing to the device to be serviced when servicing is necessary, or a portion of the servicing instrumentality may be built in or permanently positioned with respect to the device and operated by the remainder of the servicing means located in a common housing with the device or in a separate housing. Means (25) are provided to initiate and control the servicing operation.</p> |
