ABSTRACT:
A cochlear prosthetic package having a cup-shaped titanium case with a ceramic plate; a plurality of hermetically-sealed feedthroughs are formed in the plate by sintering the plate with hollow metallic tubes located in plate holes and then sealing at least one end of each tube. An electrode cable connector is provided which allows removal and replacement of a case even in the presence of body fluids. A telemetry coil is contained in a metallic tube which extends out of the case; the coil-containing tube has its two ends hermetically-sealed to the case by ceramic insulating bushings.
