In this study we propose the use of therapeutic
ultrasound as a therapy delivery technique combined with
a local asymmetrical loopless antenna for treatment
monitoring. It was determined that a 10 mm distal whip
length and 80 mm proximal whip length would be best
suited for such a catheter. These asymmetrical designs
show a decreased SNR when compared to symmetrical
loopless antennas, however, SNR measurements are still
adequate which enables one to place a transducer on the
device. These results suggest that such a catheter can
provide a minimally invasive platform for both therapy
delivery and treatment monitoring for cardiac ablation
therapies.
