Abstract
(EN)
A microelectrode probe for implantation into soft tissue comprises an envelope of flexible polymer material divided by a wall into a distal and a proximal compartment filled with matrices of biocompatible material dissolvable or degradable in aqueous body fluid and comprising a centrally disposed electrically conducting core penetrating the wall and attached to it. The core is insulated at its proximal portion from which it extends to a holder for attachment to a tissue different from said soft tissue. The envelope and the core extending distally from the holder are embedded in an additional matrix of similar kind. Also disclosed is method for its manufacture, an array comprising two or more microelectrode probes and a microelectrode probe for incorporation into the array as well as method for the manufacture of the array.

La présente invention concerne une sonde à microélectrodes pour implantation dans un tissu mou comprenant une enveloppe de matériau polymère souple divisée par une paroi en un compartiment distal et un compartiment proximal rempli de matrices de matériau biocompatible pouvant être dissous ou dégradé dans un fluide corporel aqueux et comprenant un noyau électriquement conducteur disposé au centre pénétrant dans la paroi et fixé à cette dernière. Le noyau est isolé au niveau de sa partie proximale à partir de laquelle il s'étend jusqu'à un support destiné à être fixé à un tissu différent dudit tissu mou. L'enveloppe et le noyau s'étendant de manière distale à partir du dispositif de support sont intégrés dans une matrice supplémentaire d'un type similaire. L'invention concerne également un procédé pour sa fabrication, un réseau comprenant deux sondes à microélectrodes ou plus et une sonde à microélectrodes pour incorporation dans le réseau ainsi que le procédé de fabrication du réseau.
