1. A method of cooling a medical device comprising:
- fluidly connecting a fluid reservoir to a medical device, wherein the fluid connection includes a fluid out-flow path and a fluid return path;
pumping the cooling fluid from the fluid reservoir to the medical device with a pump;
providing local indicia of cooling fluid flowing from the fluid reservoir to the pump by observing movement of a spinning member positioned within a drip chamber, the spinning member configured to spin about a longitudinal axis of the drip chamber defined by a flow path of the cooling fluid through the drip chamber, wherein the spinning member is a hollow cylinder disposed about the longitudinal axis;
energizing the medical device;
receiving at the fluid reservoir the cooling fluid containing absorbed heat from the energized medical device; and
transferring the absorbed heat to the cooling fluid in the fluid reservoir.

Abstract
A method for cooling a medical device includes fluidly connecting a cooling fluid reservoir to a medical device. The fluid connection includes a fluid out-flow path and a fluid return path corresponding to the fluid reservoir. The cooling fluid is pumped from the fluid reservoir to the medical device. The medical device is energized and the heat generated by the energization is absorbed by the cooling fluid pumped to the medical device. The cooling fluid is received at the reservoir containing the absorbed heat. The cooling fluid transfers the absorbed heat to the cooling fluid in the reservoir and to the environment adjacent to the reservoir.
