A novel balloon catheter for thermal management during surgery

不规则心跳的治疗通常使用射频心脏消融术（RFA）将热能从心脏传递到/从心脏产生病变，但这种额外的热量可能会损害周围结构，特别是食道。作为高科技心脏病、血管内和肿瘤手术产品的主要供应商，Baylis医疗公司寻求在两年内开发并推出一种新的系统，通过控制食道内腔温度，将食道肌肉温度保持在0 - 50摄氏度范围内。这将通过一种新型的气球导管/热交换器系统来实现，热流体动力学和材料开发构成了这个Engage项目的基础。新产品将很容易适用于射频（RF）设备，包括由Baylis医疗公司开发的现有高科技射频穿刺系统，从而帮助挽救那些接受射频治疗的患者的生命。预计最终的商用系统也将用于其他外科手术的加热/冷却。

Treatment of irregular heartbeat often utilizes the transfer of thermal energy to/from the heart to create a lesion, using Radiofrequency heart ablation (RFA), but this additional heat may damage surrounding structures, notably the esophagus. As a major supplier of high-technology cardiology, endovascular and oncology products for use in surgery, Baylis Medical seeks to develop and bring to market within 2 years a new system for keeping the esophagus muscle temperature within the 0 - 50 deg C range by managing the esophagus internal lumen temperature. This is to be achieved by a novel balloon catheter/heat exchanger system, the thermo-fluid dynamics and materials development of which forms the basis of this Engage project. The new product will be readily applicable to radiofrequency (RF) devices, including the existing high-tech RF Puncture System developed by Baylis Medical, thus helping to save the lives of those patients undergoing RFA treatment. It is intended that the final commercial system will also be used for heating/cooling in other surgical procedures.
