Electrode shorting

Abstract

In one embodiment, a medical system includes a catheter configured to be inserted into a body part of a living subject, and including a deflectable element having a distal end, an expandable distal end assembly disposed at the distal end of the deflectable element, and comprising a plurality of assembly electrodes, and configured to expand from a collapsed form to an expanded deployed form, a proximal electrode disposed at the distal end of the deflectable element proximally to the expandable distal end assembly, and extending circumferentially around the deflectable element, at least one electrical connection configured to electrically connect together at least two of the assembly electrodes to act as a combined assembly electrode, and an ablation power generator configured to be connected to the catheter, and apply an electrical signal between the combined assembly electrode and a selected electrode.

Dependencies are inferred from the claim text.
