Perimeter Medical Imaging AI secured FDA premarket approval for Claire, its wide‑field optical coherence tomography device integrated with AI to image excised tissue margins during breast‑conserving surgery. Claire provides high‑resolution, real‑time margin assessment intended to reduce re‑operation rates by identifying residual tumor at the time of surgery. The PMA gives Perimeter a commercial regulatory advantage in intraoperative margin assessment and may drive adoption in surgical oncology workflows seeking to reduce repeat procedures. The approval also highlights continued regulatory momentum for AI‑enabled, intraoperative diagnostic devices.
