A photodynamic mapping device includes a shaft with a proximal end and a distal end, at least one optical electrode at the distal end of the shaft, and at least one optical fiber positioned inside the shaft. In embodiments, the at least one optical fiber extends from the distal end of the shaft and is coupled to the at least one optical electrode provided at or about an outer surface of the device. In an embodiment, at least one optical fiber is coupled, at or about the proximal end of the shaft, to a light source coupled and an optical sensor. An analyzer can be coupled to the optical sensor. Embodiments of such devices can be configured to deliver substances, such as photodynamic therapeutic substances. |
