The SAVI applicator was designed to treat the tissue closest to the removed tumor by fitting into the lumpectomy cavity and delivering targeted radiation through multiple catheters.
Prior to expansion, the physician places the applicator into the lumpectomy cavity through a small incision. The physician expands the catheter bundle to conform to the inside of the cavity.
Each catheter independently delivers radiation to the tissue which allows the physician to customize the radiation dose. This customized approach minimizes the amount of radiation exposure while targeting the tissue most at risk for recurrence.3,4
After delivery of the prescribed radiation dose, the physician closes the catheter bundle and removes the SAVI applicator.
