Abstract

A medical probe can include electrodes for ablation and sensing proximity to tissue and/or monitoring electrical signals within the cardiovascular system to identify aberrant conductive tissue sites that are responsible for an arrhythmia. The electrodes can be oriented on an end effector assembly, such as a basket assembly, such that one side of an electrode is positioned to contact tissue and the opposite side is inhibited from contacting tissue. To enable both efficient delivery of energy as well as high sensitivity for ECG sensing an impedance reducing coating can be positioned on the tissue contacting side and an impedance increasing coating can be applied on the opposite side. The impedance increasing coating of an IRE electrode can be thin enough to allow energy to be delivered through the coating during ablation. An RF electrode an have sufficient mass to carry electrical energy for thermal ablation.
