A novel balloon catheter for thermal management during surgery

不规则心跳的治疗通常利用热能转移到心脏/从心脏产生损伤，使用射频消融（RFA），但这种额外的热量可能会损害周围结构，特别是食道。作为高科技心脏病学、血管内和肿瘤产品的主要供应商，Baylis Medical寻求在2年内开发并推向市场一种新系统，通过管理食管内腔温度将食管肌肉温度保持在0 - 50 ℃范围内。这将通过一种新型球囊导管/热交换器系统来实现，其热流体动力学和材料开发构成了该Engage项目的基础。该新产品将适用于射频（RF）设备，包括Baylis Medical开发的现有高科技射频穿刺系统，从而帮助挽救接受RFA治疗的患者的生命。预期最终市售系统也将用于其他外科手术中的加热/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.
