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.

不规则心跳的治疗通常利用射频心脏消融 (RFA) 将热能转移到心脏或从心脏转移来产生病变，但这种额外的热量可能会损坏周围的结构，尤其是食道。作为手术用高科技心脏病学、血管内和肿瘤学产品的主要供应商，Baylis Medical 寻求在 2 年内开发并推向市场的新系统，通过管理食道内腔温度，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。该新产品将很容易适用于射频（RF）设备，包括Baylis Medical开发的现有高科技射频穿刺系统，从而有助于挽救接受RFA治疗的患者的生命。最终的商业系统还将用于其他外科手术中的加热/冷却。
