Methods
A Medtronic 3830 lead screwed in chicken breasts delivered 50 watts RF
energy in three methods: A) direct fashion (RF catheter touching the
proximal end of the 3830 lead, acting as an extension of RF catheter),
or B) 3830 lead as a return patch (RF delivered in the bath without
contact), or C) 3830 lead as a return patch (RF delivered touching the
breast surface close to the 3830 lead screwed deep in the flesh).
Different power settings were also tested. Lesion surface area is
reported in cm2.
