Embodiment Construction

[0100] figure 1An active implantable medical device 10 is shown. The electrical bushing 100 is part of the device 10 . Device 10 includes housing 20 . The circuit board 30 is provided inside the housing 20 and has the electronic unit 50 mounted thereon. The battery 40 supplies the required electrical power to the electronic unit 50 . Capacitor 45 may be used to store the pulse energy required by the implantable defibrillator. The electrical bushing 100 according to the invention is inserted into the housing 20 in such a way that the electronic unit 50 is hermetically sealed from the surrounding environment. The electrical bushing 100 according to the present invention allows to achieve less than 1 x 10 -9 Helium leak rate atm*cm3 / sec. Moreover, it is resistant to cleaning and sterilization methods.

[0101] The channels of the electronic unit 50 are connected to the conductive elements 110 of the electrical bushing 100 by means of internal connecting elements 55 . Sai...
