Abstract

Cardiac ablation catheters and methods of use. Catheters that include an expandable membrane, an imaging member disposed within the expandable membrane, the imaging member having a field of view, a light source disposed within the expandable member adapted to deliver light towards the field of view of the imaging member, and an electrode comprising an outer conductive layer and inner light absorbing layer disposed between the electrode and the expandable membrane, the inner light absorbing layer adapted to absorb light from the light source and thereby reduce reflection of the light from the outer conductive electrode.
