Recirculating cooling systems for use with energy delivery devices

Abstract

A kit for use with a recirculating cooling system includes a bag. The bag includes a first wall, a second wall opposite the first wall, and a side wall which define a reservoir configured to retain afluid therein. A first port is defined through the first wall and a second port is defined through the side wall or the second wall. The bag is configured to maximize a temperature differential between a fluid proximate the first port and a fluid proximate the second port. Further, the bag is collapsible.

Description

technical field [0001] The present disclosure relates to the use of energy delivery devices. More particularly, the present disclosure relates to a bag configured for use with a system for cooling an energy delivery device. Background technique [0002] Various medical conditions can be treated by delivering energy. For example, procedures such as tissue ablation utilize energy delivery devices (eg, ablation needles, ablation probes, ablation catheters, etc.) to remove unhealthy tissue, including cancer cells, from a patient. Energy delivery devices may operate by direct discharge, electromagnetic energy, microwave energy, or other types of energy. Energy is typically passed through one or more electrodes, causing tissue in contact with it to be heated to ablation temperatures. [0003] During use, the energy delivery device may require cooling to maintain a safe operating temperature and avoid damage to the energy delivery device and / or surrounding tissue. In some cases...
