Surgical electrode has first lead leading to proximal first of two poles in form of helix enclosing second lead and uninsulated at least in region of proximal pole to form pole itself

摘要

Surgical electrode has curved surgical needle (3) on the end of electrode to be anchored in the heart wall. An end protrudes through thorax in operating position for connection to pacemaker or ECG monitor. First lead leads to proximal first pole (6) of two or more poles in the form of helix enclosing a second lead and uninsulated at least in region of proximal pole to form pole itself.
