Abstract
The construction of a catheter galvanic cell suitable for implantation on the surface of the cortex is described. The silver cathode has a diameter of 125 μm and is behind two 12·5 μm teflon f.e.p. membranes. It can be chemically sterillised and can easily be withdrawn between sutures. It has been used for post-operative oxygen monitoring to give, warning of cerebral hypoxia.

L'article décrit la réalisation d'une pile galvanique cathéter apte à l'implantation sur la surface du cortex. La cathode en argent présentant un diamètre de 125 μm est montée derrière deux membranes de téflon FEP de 12,5 μm. Elle peut être stérilisée chimiquement et extraite entre les sutures. Elle a été utilisée pour le contrôle de l'oxygène post-opératoire pour donner un avertisesment de l'hypoxie cérébrale.
Zusammenfassung
Es wirld der Bau einer galvanischen Katheterzelle beschrieben die sich zur Einpflanzung auf der Oberfläche der Kortex eignet. Die Silberkathode hat einen Durchmesser von 125 μm und liegt hinter zwei Teflon-FEP-Membranen von 12,5 μm. Sie läßt sich chemisch sterilisieren und ohne weiteres aus Wundnähten entfernen. Sie wurde für die Sauerstoffüberwachung nach Operationen zur Warnung vor einer Zerebralhypoxie verwendet.
