1. A device for performing a medical procedure, the device comprising:
an elongate body including a proximal portion, a distal portion having a distal end, and a longitudinal axis;
a distal tip electrode at the distal end;
at least one optical window within the distal portion of the elongate body, the at least one optical window being proximal to the distal tip electrode;
at least one lateral electrode disposed along a length of the elongate body distal portion having a plurality of electrically conductive and optically transparent areas; and
at least one flexible overlay configured to extend partially around a portion of the elongate body, the at least one flexible overlay having a plurality of layers, the plurality of layers including an inner layer configured to be in contact with the elongate body, an encapsulation layer, and at least one intermediate layer disposed between the inner layer and the encapsulation layer, the encapsulation layer having a plurality of openings corresponding to each of the plurality of electrically conductive and optically transparent areas.
