Abstract
An energy delivery device cooling system includes a reservoir connector assembly and an elongate member. The elongate member has first and second lumens in fluid communication with the reservoir. The first lumen includes an outflow port and the second lumen includes a return port each in fluid communication with the reservoir. The device further includes a tubing system having a first end and a second end. The first end connected in fluid communication with the outflow port and the second end in fluid communication with the return port. The second end configured to return a fluid to the reservoir. The tubing system connects to an energy delivery device to cool the fluid.
Claims20
An medical device cooling system, the system comprising:
- a reservoir connector assembly connectable to a reservoir and including:
- an elongate member configured to extend into the reservoir, the elongate member including a first lumen and a second lumen defined therethrough, each lumen in fluid communication with the reservoir;
- at least one outflow port in fluid communication with the first lumen;
- and
- at least one return port in fluid communication with the second lumen;
- and
- a tubing system comprising a first end and a second end, the first end connected to and in fluid communication with the outflow port, the second end connected to and in fluid communication with the return port, the tubing system configured to cool a medical device.
A fluid return elbow for use with a medical device cooling system, the elbow comprising:
- a body defining a lumen;
- an inflow port in fluid communication with the lumen, the inflow port configured to connect to a return section of a fluid tubing system;
- and
- an outflow port in fluid communication with the lumen, the outflow port configured to connect to a return port of a reservoir connection assembly.
A system for cooling a medical ablation device, the system comprising:
- a fluid reservoir configured to hold a cooling fluid;
- a tubing system connected to and in fluid communication with the fluid reservoir;
- a pump connected to the tubing system and configured to induce the cooling fluid to flow from the reservoir through the tubing system;
- the medical ablation device connected to the tubing system configured to allow the cooling fluid to flow through the medical ablation device and draw heat therefrom, wherein the tubing system is connected to the fluid reservoir such that the fluid is returned to the fluid reservoir and reused;
- and
- a fluid flow indicator configured to provide indicia of the flow of cooling fluid through the system.
