A Medical Device Daily

Cianna Medical (Aliso Viejo, California) reported that the U.S. Patent and Trademark Office issued two patents that are related to its SAVI multi-catheter brachytherapy device for the treatment of breast cancer.

The patents, Nos. 7,497,819 and 7,497,820 and titled "Expandable Brachytherapy Device," represent the first patents issued for a family of applications focused in brachytherapy.

The SAVI multi-catheter open architecture design allows for the delivery of patient-specific radiation that minimizes the radiation dose to healthy tissue. Published reports and clinical experience show that most women who are excluded from balloon brachytherapy because of the location of the lesion or breast size can receive treatment with the SAVI delivery system.

"These two patents are the first of many we expect to secure through our comprehensive intellectual property portfolio," said Jill Anderson, president/CEO of Cianna. "We are well positioned to protect our products and our leadership in the breast brachytherapy market. Strong IP and innovative, proven technology make Accelerated Partial Beast Irradiation (APBI) with SAVI a viable therapy for women suffering from breast cancer."

Cianna received FDA 510(k) clearance for SAVI in August 2007 for use during brachytherapy procedures. For appropriate patients, SAVI is an advanced technology that may reduce treatment time to just five days, vs. six to eight weeks for traditional radiation therapy, Cianna said.

Cianna is a device company focused on women's health and dedicated to the treatment of early-stage breast cancer. The company makes the SAVI breast brachytherapy applicator, for the delivery of radiation after lumpectomy surgery. According to the company, the SAVI applicator allows contouring of the radiation dose, and is designed to make the benefits of accelerated partial breast irradiation available to a greater number of women.
