1. An illumination and treatment catheter for use with a power supply and for illuminating tissue, the catheter comprising:
- a shaft having an outer shaft surface and a far end adapted for insertion into a body of a patient;
a plurality of energy transfer elements forming an expandable assembly, the plurality of energy transfer elements being coupled to the far end of the shaft and being configured to apply a therapeutic energy to the body lumen at a treatment site, wherein at least one of the plurality of energy transfer elements includes an active region defined at a proximal end by a first insulating region and at a distal end by a second insulating region, wherein the therapeutic energy is selected from the group consisting of radio frequency, microwave, and ultra sound; and
an illumination source affixed directly on at least one of the plurality of energy transfer elements, wherein the illumination source is adapted to provide a visualization energy at the treatment site that is different than the therapeutic energy, wherein the illumination source is disposed on at least one of the first insulating region and the second insulating region of the at least one of the plurality of energy transfer elements.

25. An illumination and treatment catheter for use with a power supply and for illuminating tissue, the catheter comprising:
-
a shaft having an outer shaft surface and a far end adapted for insertion into a body of a patient; a plurality of energy transfer elements forming an expandable assembly, the plurality of energy transfer elements being coupled to the shaft and configured to apply a therapeutic energy to the body lumen, wherein at least one of the plurality of energy transfer elements includes an active region defined at a proximal end by a first insulating region and at a distal end by a second insulating region; an illumination source located towards the far end of the shaft and affixed directly to at least one of the plurality of energy transfer elements, wherein the illumination source is configured to provide a non-therapeutic energy within the body lumen, wherein the energy transfer element and the illumination source are configured to deliver the therapeutic and non-therapeutic energies, respectively, and wherein the illumination source is disposed on at least one of the first insulating region and the second insulating region of the at least one of the plurality of energy transfer elements. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
