MammoSite targeted radiation therapy system

At Hologic, our mission is to make breast cancer intervention and treatment as minimally invasive as possible. Help your patients get back to their lives in just five days with the MammoSite targeted radiation system.

The MammoSite 5-Day system is the most widely utilized and accepted method of accelerated partial breast irradiation (APBI). Balloon brachytherapy products allow physicians to offer early-stage breast cancer patients a more compassionate option, while providing a more efficient therapy treatment compared with whole breast radiation. 

About

Our MammoSite products offer straightforward treatment planning along with a flexible catheter shaft designed to maximize patient comfort. Balloon-based therapies directly target the lumpectomy cavity, where the cancer is most likely to recur. 

With targeted radiation therapy, healthy tissues and organs can be spared from the damaging effects of radiation.1,2 Choose from a single or multi-lumen system to better achieve your clinical requirements and your patient’s need for more convenient care.

 The MammoSite system is:

  • Compassionate:

o    Delivers optimal clinical outcomes, resulting in fewer side effects compared to traditional whole breast irradiation.

o    Maximizes patient comfort by providing a flexible catheter shaft.

  • Flexible:

o    Multi-lumen configuration allows for ideal treatment planning, enabling more women to be treated with 5-Day targeted radiation therapy.

o    Balloon catheters range in size from 3.5 – 5.0 cm in diameter with a broad range of inflation volumes.

  • Accurate

o    Localized radiation treatment expedites the course of therapy from five to seven weeks to just five days.

o    Delivers optimal treatment coverage, while minimizing excess radiation to surrounding skin and ribs.

Accessories

Cavity evaluation device (CED)  

  • Used to assess the lumpectomy cavity and aid in the selection of the appropriate MammoSite single- or multi-lumen applicator.  
  • Can be used during surgery to assess skin spacing and conformance.
  • May also be left in the lumpectomy cavity as a placeholder until it is exchanged for the MammoSite applicator3

  • Contains two sets of four individual marker wires to facilitate efficient treatment planning.
 
 
Important Safety Information

The Mammosite device is intended to provide brachytherapy when the physician chooses to deliver intracavitary radiation to the surgical margins following lumpectomy for breast cancer. Do not implant the Mammosite device in patients with extreme or unusual anatomical features, e.g., extreme rib curves or very unequal amounts of breast tissue in the lumpectomy cavity.

The safety and effectiveness of the Mammosite radiation therapy system as a replacement for whole breast irradiation in the treatment of breast cancer has not been established.

Please see the Mammosite IFU for full prescribing information.
