The derivation and induction of organ currents should also be proven Organs are made possible by them.
Stand der Technik: El Sherif et al. (19775 beschreiben eine Composite-Elektrode, die iSber parallel laufende Druhte eine bipolare Ableitung epikardialer Ströme ermöglicht (El Sherif N, Scherlag BS Lazarra R, Circulation 55 , 686 (1977)).Diese Elektrode erwies sich nach der Implantation in Eigen experimenten als nur fr einen Zeitraum von wenigen Tagen brauchbar. Zur Herstellung dieser Elektrode wurden Drähte und Textilstoff verwendet.Prior art: El Sherif et al. (19775 describe a composite electrode, the iSber parallel running pressure enables a bipolar discharge of epicardial currents (El Sherif N, Scherlag BS Lazarra R, Circulation 55, 686 (1977)) This electrode proved to be only for a period of time after the implantation in own experiments usable within a few days. To make this electrode, wires and Textile used.
Kritik des Standes der Technik: Mit der Verwendung der bisherigen Technik gelingt es nicht, die Oberflächenreibung und das Abscheren von Orahtelementen im Elektrodenbereich zu vermeiden.Criticism of the prior art: With the use of the previous Technology fails to reduce surface friction and shear off Wire elements to be avoided in the electrode area.
Eine Langzeitimplantation dieser Elektroden an bewegten Organen geht daher mit Fehlableitungen bzw.Long-term implantation of these electrodes on moving organs is possible therefore with incorrect derivations or
fehlender Induzierbarkeit von elektrischen Strömen und Potentialen einher. In experimentellen Eigenbeobachtungen lassen sich bei der Verwendung dieser Elektroden Organschäden bereits nach kurzer Expositionsdauer nachweisen.lack of inducibility of electrical currents and potentials hand in hand. Experimental self-observations can be made when using this Electrodes detect organ damage after a short period of exposure.
Lösung: Diese rufgabe wird erfindungsgemäß dadurch gelöst, daß die langzeitimplantierbare Flächenelektrode eine physiologisch inerte und mittels Aufdampfen eines Leiters oder galvanischer Metallbeschichtung leitfähig gemachte Matrix aufweist.Solution: This task is solved according to the invention in that the Long-term implantable surface electrode a physiologically inert and vapor-deposited electrode a conductor or galvanic metal coating has made conductive matrix.
Um eine möglichst große KontaktFläche dieser Elektrode an bewegten Organen zu erreichen, werden flexible Kunststoffe, vorzugsweise Polyesterstoffe(z. B. Oacron R als Matrix verwendet.In order to move this electrode to as large a contact area as possible To reach organs, flexible plastics, preferably polyester fabrics (e.g. B. Oacron R used as a matrix.
Es ist nach an sich bekannten Kathoden möglich, eine selektive galvanische Beschichtung einzelner Elektrodenbersiche auf der Pratrix vorzunehmen.It is possible according to known cathodes, a selective galvanic Coating of individual electrode surfaces on the pratrix.
Erzielbare Vorteile: Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die langzeitimplantierbare FlGchenelektrode vorzugsweise an bewegten Organen (z.H. Herz, Darm) nahezu keine Oberflächenreibung verursacht, physiologisot' weitgehend inert ist und die Musuahl verschiedener llbleitungsmuster mit einem elektrischen Leiter srmöglicht. Die hohe Verformbarkeit der beschichteten Elektrodencberflche fffihrt an bewegten Organen zu einem größtmöglichen Kontaktbereich zur Ableitung oder Induktion von elektrischen Strömen und Potentialen.Achievable Advantages: The advantages that can be achieved with the invention exist in particular that the long-term implantable surface electrode is preferred causes almost no surface friction on moving organs (e.g. heart, intestines), physiologically isot 'is largely inert and the range of different wiring patterns with an electrical conductor. The high deformability of the coated Electrode surface leads to the largest possible contact area on moving organs for the derivation or induction of electrical currents and potentials.
Gewerbliche Anwendung: Die nach dem Oberbegriff des Anspruchs 1 bezeichnete Erfindung kann in der medizinischen Diagnostik und Therapie (z.n. Neurochirurgie) Verwendung finden.Commercial application: The one designated according to the preamble of claim 1 Invention can be used in medical diagnostics and therapy (e.g. neurosurgery) Find use.

The electroplating of the electrode takes place after methods known per se. The silver is cathodic from a solution of Potassium cyanogenate (I) deposited on the introduced tissue.
Durch den Einsatz von Photosensibilisatoren (z.S.Through the use of photosensitizers (e.g. p.
Silberbromid) und isolierenden Substanzen (z.t2'. Silberkautschuk) kann die gewünschte Kontaktfläche auf dem Elektrodengewebe genau festgelegt werden.Silver bromide) and insulating substances (partly silver rubber) the desired contact surface on the electrode fabric can be precisely determined.
Isolierte Drahte, die auf der Rückseite der Elektrodenfljche befestigt werden können, ermöglichen die Stromfhrung.Insulated wires attached to the back of the electrode area enable electricity to be carried.
