Description

Isolierter unipolaren Hertzschrittmacher Bei implantierbaren Hertzschrittmachern unterscheidet man, je nach Art der Elektrodenkabel, zwischen unirolaren und bipolaren Schrittmachern. mei binolaren Schrittmachern geht vom Schrittmacher ein zweiadriges Kabel ins oder an das Herz, um dieses mittels zweier nebeneinander liegender Elektroden zu stimmulieren. Rei unipolaren Schrittmachern fiihrt lediglich ein einedriges Fabel mit einer Elektrode zum Herzen.Isolated unipolar heart pacemaker For implantable heart pacemakers Depending on the type of electrode cable, a distinction is made between unirolar and bipolar Pacemakers. With binolar pacemakers, there is a two-wire pacemaker Cable into or to the heart, around it by means of two electrodes lying next to each other to stimulate. For unipolar pacemakers there is only one single fable with an electrode to the heart.

Die Gegenelektrode befindet sich am Schrittmacher selbst.The counter electrode is located on the pacemaker itself.

Um der Schrittmacher vor elektromagnetischen Störfeldern zu schlitzen, wird dieser in ein Metallgehäuse eingekapselt. Bel unipolaren Schrittmachern ist dann das ganze Metallgegäuse gleichzeitig Gegenelektrode zur TTerzelektrode.To cut the pacemaker from electromagnetic interference fields, this is encapsulated in a metal housing. Bel is unipolar pacemakers then the whole metal housing at the same time counter electrode to the core electrode.

Dadurch, daß das ganze gehause als Elektrode ausgebildet ist, läßt es sich nicht immer vermeiden, daß synchron mit der Herzstimmulation Nerven an der Implantationstelle gereizt werden.Because the whole housing is designed as an electrode, can it cannot always be avoided that nerves are synchronized with the cardiac stimulation Implantation site are irritated.

Das entstehende Muskelzucken zwinkt, bei manchen Patienten bipolare Elektroden zu verwenden, oder den Implantationsort zu ändern, Die im nachfolgenden beschriebene erfindung zeigt ein Verfahren, um dieses Muskelzucken zu vermeiden.The resulting muscle twitching beckons, in some patients bipolar To use electrodes or to change the implantation site, see below The invention described shows a method to avoid this muscle twitching.

5-er Schutz gegen C;tiirfelder bleibt erhalten, wenn die Metallkapsel mit einer Isolierschicht überzogen ist. Eine freie Stelle in dieser schicht gewshrlei.stet andererseits, dsß die Elektrodenwirkung erhalten bleibt. Diese Elektrodenfläche kann dann bei Implantation einer unempfindlichen Stelle im orper zugewandt werden. Um eine Vergröberung des Schrittmachers durch die zusätzliche Isolationsschicht zu vermeiden, kann aber auch die Metallhülle unterbrochen werden und durch einen schmalen geschlossenen Spalt oder Isolierschicht getrennt, die entstehende Elektrodenplatte allein unter Spannung gesetz werden.5 protection against C; door fields are retained if the metal capsule is covered with an insulating layer. There is always a vacancy in this shift on the other hand, that the electrode effect is retained. This electrode area can then be turned towards an insensitive area in the orper during implantation. To make the pacemaker coarser through the additional insulation layer to avoid, however, the metal shell can be interrupted and by a narrow closed gap or insulating layer separated the resulting electrode plate to be acted alone under tension.
