SenoRx Receives Additional 510(k) Clearance for Its Contura MLB

ALISO VIEJO, Calif., July 1, 2008 (Healthcare Sales & Marketing Network) -- SenoRx, Inc. (NasdaqGM:SENO ) today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for a second Contura(tm) MLB short-term breast radiation balloon design.

``The novel proprietary design of our newest Contura Multi-Lumen Radiation Balloon (MLB) Catheter allows the clinician greater flexibility in appropriately fitting the lumpectomy cavity with a Balloon catheter,'' said Lloyd Malchow, SenoRx President and Chief Executive Officer. ``The new-size Contura balloon may be appropriate for approximately 10 to15 percent of patients where a larger balloon is warranted and will allow us to compete for these cases. The product is currently being evaluated at several clinical sites and is expected to become generally available during the third quarter of 2008. The original Contura is 4 to 5 centimeters in diameter, while the new balloon can be used for larger lumpectomy cavities ranging from 5 to 6 centimeters in diameter.''

About Contura(tm)

SenoRx received 510(k) clearance from the U.S. Food and Drug Administration on May 23, 2007 for Contura(tm), its Multi-Lumen Radiation Balloon (MLB) catheter 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 can 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. Some patients who are potential candidates for balloon therapy are currently excluded because of the location of the lesion and their breast size. Contura's advanced multi-lumen design may address this issue for certain patients. In addition, the Contura MLB uses vacuum to remove excess seroma and air to enhance conformance of often irregularly shaped lumpectomy cavity walls to the balloon surface in order to deliver precise radiation dosing through multiple radiation source lumens. SenoRx has been granted three patents related either to the design or manufacturing of Contura MLB. The first procedures using the original Contura MLB took place in late June 2007.
