Abstract
A biopsy site marker configured to expand upon deployment into a biopsy cavity, and visible under several different imaging modalities, comprises a superabsorbent hydrogel component and a radiopaque element. The hydrogel is in a compressed, dehydrated state prior to deployment to facilitate placement of the marker within the biopsy site, and thereafter expands upon deployment in the biopsy site. Such expansion limits migration of the site marker.
