Visual electrode ablation systems are described herein which include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An electric current may be passed through the fluid such that it passes directly to the tissue region being imaged and the electrical energy is conducted through the fluid without the need for a separate ablation probe or instrument to ablate the tissue being viewed.

A Peltier effect cooling device is formed in combination with an electronic device to form a unique thermal and electrical relationship. An electronic device to be cooled is placed in a serial electrical relationship between at least two thermoelectric couples while simultaneously being in thermal contact with a cold side of the cooler arrangement. The same current which produces the thermoelectric effect in the Peltier thermocouples also drives the electronic device. A balanced effect results as a higher driving current through the electronic device causes greater heating, it is offset by the added cooling due to a greater current in the thermocouples. In addition, a unique spatial arrangement provides improved heat distribution and transfer to a heat sink. Due to the unique shapes of Peltier elements, heat is pulled radially from a heat generating source and distributed at a peripheral region. Shaped Peltier elements are tapered from a small cold area to a large hot area to further magnify the transfer of heat.
