Patent ID: 8491636

Claim:
A medical system, comprising: an energy treatment device; a first lumen and a second lumen each in fluid communication with the energy treatment device; a first coolant reservoir; a second coolant reservoir, wherein the first coolant reservoir is selectively switchable between a first and second fluid pathway, the first fluid pathway being in fluid communication with the first lumen and the second fluid pathway being in fluid communication with the second coolant reservoir; and a vacuum source, wherein the second lumen is selectively switchable between a third and fourth fluid pathway, the third fluid pathway being in fluid communication with the second coolant reservoir and the fourth fluid pathway being in fluid communication with the vacuum source, and wherein the second coolant reservoir is coupled to the vacuum source through a fifth fluid pathway, wherein during operation of the energy treatment device, fluid is transferrable from the first coolant reservoir to the second coolant reservoir and then from the second coolant reservoir to the energy treatment device through the third fluid pathway.
