Breast Tumor Localization Implant Removes Time Constraints

The system is based on a passive reflector placed in the target tissue prior to surgery by an interventional radiologist. During the procedure, the surgeon uses a special handpiece that emits EM radar waves to locate the reflector and plan the incision.

The reflector is completely passive until activated, allowing patients to continue with all activities; and because it does not interfere with magnetic resonance imaging (MRI) scans, it provides physicians with maximum flexibility for its localization at any time during the continuum of care. During the lumpectomy or surgical biopsy, the surgeon scans the breast using the Scout guide, which emits 50 million pulses per second, in order to lock on to the reflector’s position. The reflector and target tissue can then be safely removed.

“I applaud the vision of all our physicians and health systems who are leading the way in offering a new standard of care in breast tumor localization,” said Jill Anderson, President and CEO of Cianna Medical. “Scout has become the most precise and broadly applicable non-wire localizing system in the industry, and more than 170 leading medical centers across the United States have adopted Scout radar breast localization and surgical guidance system as an alternative to placing wires on the day of surgery.”

The standard preoperative technique for localizing non-palpable breast lesions, developed more than 20 years ago, is wire localization, which involves a radiopaque wire inserted into the breast by a radiologist prior to surgery using mammography or ultrasound guidance. The surgeon can subsequently be guided directly to the target tissue.
