Tissue Puncture Thermal Impact
During RF application, heat distribution was visually larger in the case of electrified guidewires compared to the RF wire by thermal imaging (Figure 6). Peak temperature at the core of the heated area exceeded 100°C using electrified guidewires compared to approximately 30°C using the RF wire, indicating a greater temperature increase relative to baseline (room temperature). The larger heating area and higher peak temperature at the core were observed at all power settings when electrified guidewires were used relative to the RF wire.
