The INTACT Breast Lesion Excision SystemThe INTACT Breast Lesion Excision System (BLES) captures breast tissue for histological review, using RF (Radiofrequency) energy and disposable instruments. The process is guided with ultrasound to perform lumpectomy through a small incision and for biopsy afterwards. RFA (Radiofrequency Ablation) is performed for hemostasia. The minimally invasive procedure only leaves a 5 mm cut which gives very little change to the overall appearance.
