SenoRx Announces Additional Patent Granted for Contura(tm) Multi-Lumen Radiation Balloon (MLB)

IRVINE, Calif., Dec 18, 2008 (GlobeNewswire via COMTEX) -- SenoRx, Inc. today announced that the United States Patent and Trademark Office has granted the company its sixth brachytherapy-related patent and fourth patent directly related to its Contura(tm) Multi-Lumen Radiation Balloon (MLB) catheter for the treatment of breast cancer. The new claims allowed in United States Patent No. 7,465,568 add to SenoRx's current intellectual property relating to asymmetrically irradiating a patient's breast with the Contura MLB after breast biopsy or lumpectomy procedures.

SenoRx received 510(k) clearance for Contura MLB from the U.S. Food and Drug Administration in May 2007 for delivering radiation to the tissue surrounding the lumpectomy cavity following surgery for breast cancer. For appropriate patients, Contura MLB is one of a new class of devices which may reduce treatment time to five days from six to eight weeks. SenoRx believes that the Contura MLB may play an important role in the shift from traditional whole breast radiation therapy to localized partial breast radiation therapy.
