Abstract
Implantable devices are disclosed for marking the location of a biopsy or surgery for the purpose of identification. The devices are remotely delivered, preferably percutaneously. Visualization of the markers is readily accomplished using various state of the art imaging systems. Using the inventive systems, it is possible to permanently mark the location or margins of a lesion or other tissue site, prior to removing or sampling same. The markers function to provide evidence of the location of the lesion after the procedure is completed, for reference during future examinations or procedures.
