Abstract
A medical instrument is disclosed. The medical instrument includes a transmission line suitable for the transmission of electromagnetic energy and an antenna coupled to the transmission line. The antenna is configured for generating an electromagnetic field sufficiently strong to cause tissue ablation. The medical instrument further includes a reflector arranged to be electrically coupled to the transmission line. The reflector is positioned laterally to a first side of the antenna and configured for redirecting a portion of the electromagnetic field to a second side of the antenna opposite the reflector, wherein a majority of the electromagnetic field is directed away from the second side of the antenna.
