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.
