Summary
The development of microwave cardiac ablation system is crucial to the development towards a permanent cure for cardiac arrhythmias. Cardiac ablation using microwave energy can overcome the limitations of current ablative energy such as laser and RF ablation.

Based on the combined knowledge and experience of UTS and Westmead hospital researchers, the proposed research is to develop a working prototype of cardiac ablation system using microwave energy based on our patent. The ultimate aim would be to attract interested industry parties to take up for full production and commercialisation.Read moreRead less
Improved electrophysiological mapping techniques have enhanced understanding of arrhythmia mechanisms and the development of curative ablation strategies. Advanced mapping systems utilize online visualization of catheters, 3D geometry, and annotation of ablation sites. To date, all commercially available systems rely on proprietary equipment to locate catheter positions and reconstruct chamber shape from multiple site recordings. Thus, cost is prohibitive, limiting widespread availability.

Advanced mapping systems utilize online visualization of catheters, 3D geometry, and annotation of ablation sites. To date, all commercially available systems rely on proprietary equipment to locate catheter positions and reconstruct chamber shape from multiple site recordings. Thus, cost is prohibitive, limiting widespread availability. An alternative approach has emerged with the use of CT-MRI imaging and analysis. Novel techniques extract images of the endocardial surface from CT-MRI for use in electrophysiological mapping. This surface can be used as the chamber geometry instead of reconstruction based on expensive technology measuring spatial coordinates of the catheter tip inside heart. The proposed Anatomical Template Mapping System (ATMS) will generate maps of electrophysiological parameters derived from catheter recordings without the need for proprietary equipment. The physician will direct the virtual catheter position onto the 3D model of the chamber, obviating the need for equipment to map the spatial distribution of the catheters. The major advantage is that, without the need for specialized equipment, this method of mapping is substantially cheaper and can be used with any conventional electrophysiological mapping systems. Furthermore, it will provide the most important feature of the advanced mapping systems - an understanding of the arrhythmia mechanism.Read moreRead less
