Electrode catheter, in particular for cardiac therapy

摘要

The electrode catheter has an elongated tube-type catheter portion (1). A ring electrode (3) is arranged before a distal end (2) of the electrode catheter for the delivery and measurement of an electrical electrocardio signal by way of an outer electrode contact surface (4). A supply lead is provided for the electrical connection of the ring electrode. The ring electrode is mounted on the catheter tube such that it can be displaced relative in a longitudinal axial direction.
