STING MARK Universal Fiducial Marker System

Currently available fiducial marker and fiducial insertion strategies are rudimentary, imprecise, not compatible with multiple insertion catheters/needles and are overall unreliable. STING-MARK device is the first universal, fully detachable and non-premounted radiopaque fiducial device system. Allowing biopsy prior to insertion, STING-MARK is easily and reliably delivered through-the-needle to the tumor, in order to accurately pinpoint its location for image-guided therapies. This study aims at establishing proof of concept for STING-MARK, by demonstrating its usability, reproducibility, radio-opacity and retention in a variety of clinically-relevant ex vivo organ samples.
