Abstract
In an embodiment, an implantable marker, which is adapted to be implanted into patient tissue using a hollow needle, includes a marker body including a radiopaque material and a polymeric material that encapsulates at least a portion of the marker body. In an embodiment, an outer surface of the encapsulating material includes one or more protrusions to reduce a tendency of the marker to migrate and rotate within a patient's body after implantation.
