Integer: Improved feedthrough for implantable devices
The company has designed a feedthrough that is much smaller than the traditional feedthrough and is hermetically sealed to protect the electronics and the patient, according to Keith Seitz, senior director of research and development for Frisco, Texas–based Integer.
The traditional feedthrough is formed of aluminum oxide with gold-brazed platinum wires. The new technology injects platinum into a green aluminum oxide ceramic body and is then co-fired at high temperatures to form a biocompatible hermetic feedthrough.
The proprietary forming method for the co-fired platinum/aluminum oxide technology enables the creation of smaller vias and less aluminum oxide ceramic between vias when compared to traditional feedthrough insulators that require core rods to be extracted from the green body during pressing of aluminum oxide-pressed ceramics.
