Title
(EN) ELECTRODE ARRAY AND METHOD OF MANUFACTURE
(FR) RESEAU D'ELECTRODES ET PROCEDE DE FABRICATION
Abstract
(EN) The electrode array is a device for making multiple electrical contacts with cellular tissue or organs. The electrode array includes a base (1), a two dimensional array of conducting protuberances (2) arising from the base and serving as electrodes, and conductors (3) embedded onto the base and connected to such protuberances for transmitting electrical signals to and/or from the protuberances. The protuberances may also include an insulating layer (15) which covers either the entire protuberance or which leaves the tips exposed for making focused electrical contact. Electrode arrays may be used singly or in combination with a second electrode array so as to form a sandwich around a target tissue. The sandwich electrode array (16, 17) may employ indexing cones for aligning the opposing electrode arrays and for limiting their vertical proximity. The conductors of the electrode array may be electronically connected or coupled to processing circuitry which amplifies and analyzes the signal received from the tissue and/or which generates signals which are sent to the target tissue and possibly coordinates the generated signals with signals which originate with the tissue.
(FR) Le réseau d'électrodes est un dispositif permettant de réaliser des contacts électriques multiples avec des organes ou tissus cellulaires. Le réseau d'électrodes comprend une base (1), un réseau bidimensionnel de protubérances conductrices (2) faisant saillie depuis la base et servant d'électrodes, et des conducteurs (3) noyés sur la base et connectés à ces protubérances pour transmettre des signaux électriques vers les protubérances et/ou provenant des protubérances. Les protubérances peuvent également inclure une couche isolante (15) qui soit recouvre toute la protubérance soit laisse les pointes exposées pour réaliser un contact électrique focalisé. Les réseaux d'électrodes peuvent être utilisés seuls ou en combinaison avec un second réseau d'électrodes de manière à former un sandwich autour d'un tissu cible. Le réseau d'électrodes sandwich (16, 17) peut utiliser des cônes d'indexation pour aligner les réseaux d'électrodes opposés et pour limiter leur proximité verticale. Les conducteurs du réseau d'électrodes peuvent être connectés ou couplés électroniquement à un circuit de traitement qui amplifie et analyse le signal reçu du tissu et/ou qui génère des signaux lesquels sont envoyés au tissu cible, ce circuit de traitement pouvant aussi assurer une coordination entre les signaux générés et les signaux émanant du tissu.
