1. A method of constructing an inflatable irrigated electrode assembly for an electrophysiology catheter, the method comprising:

  • providing a flex circuit having a substrate with a pre-formed aperture, the substrate having a higher heat resistance;

    providing an inflated balloon member with a flexible membrane, the membrane having a lower heat resistance;

    affixing the substrate to the membrane with adhesive; and

    applying heat through the pre-formed aperture of the substrate, the heat creating a temperature sufficient to melt a portion of membrane and the adhesive without melting the substrate, the portion of the membrane and the adhesive melted forming an aperture in the membrane and adhesive.
