SAVI® Brachy combines the tissue-sparing dosimetry of interstitial brachytherapy with single-entry ease. This strut-based approach is designed to maximize ease of use during placement while providing unparalleled dose customization.

How SAVI Brachy Works

SAVI Brachy uses thin tubes (catheters) to deliver radiation directly to the lumpectomy site. The catheters gently expand to fit the size and shape of the tumor cavity. A tiny radiation seed travels through each catheter to deliver a precise dose of radiation, customized for the exact size, shape or location of your tumor cavity.


The SAVI Brachy applicator is gently inserted in a closed position into the tumor cavity through a small incision, a procedure that is usually done in your physician's office.


The catheters are gently expanded to conform to the shape of your cavity. This is done only once, at the beginning of your treatment.

Radiation Delivery

Once the catheter is in place, you will go to your radiation oncologist to begin treatment, which is delivered twice a day for five days or less.The ends of the catheters are connected to a computerized delivery system that painlessly delivers a tiny radioactive seed into each tube. The radiation source is completely removed after each treatment - no radiation remains in your body between treatments.


After your last radiation treatment, your physician will close the device and remove it through the same incision into which it was originally inserted.
