A intravascular heat exchange catheter includes a catheter body having a proximal end connectable with a heat exchange fluid source and a distal end insertable into the vasculature of a patient to facilitate heat transfer with flowing blood. The user interface includes a list of fractions identified in the treatment plan, data identifying delivery status of the fraction, and data identifying a processing status of the fraction. A middle row of facets extends angulated downward therefrom, and a lower row of trapezoidal facets extends down from them. In another embodiment, the ink has a coloring agent content in a range of 2. The electrical leads are arranged so that the plurality of finger shaped structures forms inter-digital patterns where the semiconductor dies are bonded to the lead frame structure.
