Abstract :
The design of a floating sleeve antenna for a cardiac ablation procedure is presented. The antenna can produce localized heating of the myocardium in a controllable and effective manner. In vitro experiments were performed on phantom models and on an isolated perfuse goat´s heart to identify how much power would be required to effectively ablate myocardial tissue during microwave ablation. The results highlight the ability of the floating sleeve catheter antenna to produce high specific absorption rate (SAR) values near the tip and very low SAR values along the antenna length.
