Abstract
These are site marking devices for marking a selected site within tissue of a patient. More particularly, the devices include an elongated body of gel and a metallic band disposed at least partially surrounding the body of gel. The body of gel is recognizably artificial when the marker is subject to ultrasound or x-ray imaging. Therefore, it is readily distinguishable from biological features within the tissue site.
