Elektrodenstruktur für eine multipolare Detektions-/Stimulationsmikrosonde zur Implantation in ein Herz- oder Hirngefäß

摘要

The multi-polar lead has microcables (21,22a,22b) in which each having a central conductor (23) for connection to electric stimulation or detection device. Ring (10) has lumens (11,12a,12b) in which each sized to receive a microcable of microcables. One of lumens is a connection lumen which receives the microcable of microcables. Ring has connection element that is movable into connection lumen to pierce a sheath (24) of microcable and to press into the central conductor of microcable received by connection lumen. Portion of ring is electrically connected to central conductor.
