Die Patentanmeldung offenbart eine Kontaktfeder zur elektrischen Kontaktierung eines am distalen Ende einer Elektrodenleitung befindlichen Elektrodengehäuses und einer innerhalb des Elektrodengehäuses befindlichen Welle, wobei die Kontaktfeder einen Außendurchmesser mit einem Mittelpunkt aufweist, der mit dem Gehäuse elektrisch leitend verbindbar ist.The contact spring (1) has an outer contour having a central axis (11), which is contacted in an electrically conductive manner with the housing. A wire is shaped so that two legs are formed inside the outer contour. The position of the two legs in a contacted state of the contact spring is moved away to predetermined location in non-contacted state by the force action. The outer contour is formed from four to ten wire windings. An independent claim is included for electrode lead for comprehensive cardiology application.
