  • Patent number: 10625084
    Abstract: An RF switchable filter feedthrough housed inside an AIMD is described. The RF switchable filter feedthrough includes an RF switch having a switching pole that is configured to be controlled by an AIMD control signal to switch between first and second throw position. In the first throw position, a conductive leadwire hermetically sealed to and disposed through an insulator is electrically connected to a two-terminal MLCC chip capacitor which in turn is electrically connected to the ferrule. In the first throw position, EMI energy imparted to a body fluid side implanted lead is diverted to the housing of the AIMD by the chip capacitor. In the second throw position, the conductive leadwire is electrically connected to an RF source disposed inside the AIMD housing. In the second throw position, by measuring a reflective return signal from the RF source it can be determined whether the implanted lead has a defective lead conductor.

  • Patent number: 10583302
    Abstract: The application of a titanium hydride coating on a ceramic, preferably an alumina ceramic, as a facile and inexpensive approach to bond gold to the ceramic during brazing is described. During the brazing process, the deposited titanium hydride is first partially decomposed to form pure titanium intermixed with titanium hydride. The combination of pure titanium and titanium hydride contributes to improved adhesion of gold with the alumina ceramic without any detrimental reaction between pure titanium and gold. The titanium hydride coating can be applied by dip/spray/paint coating.
