Abstract
Die Erfindung betrifft einen Ablationskatheter mit einem längsgestreckten Katheterschaft, der an seinem distalen Ende eine expandierbare Elektrodenanordnung aufweist, die im kraftlosen Zustand speichenartig nach außen klappende Elektrodenträger aufweist, welche über ein Biegegelenk distal an dem Katheterschaft befestigt und im Bereich ihres dem Biegegelenk abgewandten Endes mit Zugelementen verbunden sind, welche zum Überführen der Elektrodenanordnung von einem expandierten Zustand in einen kontrahierten Zustand relativ zum Katheterschaft längsbeweglich angeordnet sind.
