Leaky-wave antennas for medical applications

摘要

A device for directing energy to a target volume of tissue includes a proximal portion including a first antenna assembly extending therethrough, and a distal portion including a second antenna assembly. The first antenna assembly includes a leaky-wave antenna assembly having an outer conductor and an inner conductor disposed within the outer conductor. The distal portion of the device is attached to the inner conductor. The outer conductor includes a plurality of radiating apertures defined in a distal portion thereof and is configured for radiating energy substantially uniformly along a longitudinal axis of the proximal portion.
