BSD Medical Obtains Patent on Innovative Design for Heat Therapy Devices

Wednesday, September 29, 2010

Salt Lake City, UT -- BSD Medical Corporation (Nasdaq: BSDM) (the “Company” or “BSD”) announced today that a patent has been issued to the Company for a new class of heat therapy applicators (antennas). The United States (US) patent office issued the new patent, “Transparent electromagnetic applicator and hyperthermia treatment method,” to BSD for a unique design for antennas that provides significant benefits for heat therapy applications. These novel antennas have a transparent surface, which provides the significant advantage of allowing the physician to see the skin surface through the contacting antenna during a treatment. The unique design also utilizes a significantly smaller antenna that can be combined in groups to utilize BSD’s synchronous phased array technology, which was developed by the Company to improve the delivery of heat therapy by directly targeting heating to the tumor. There are five different antenna types and sizes that are part of this new class of antenna, which allows BSD to combine up to 24 antennas into a single applicator and utilize sophisticated heating pattern steering to shape the energy field to the individual tumor. BSD has been designing heat therapy systems for 32 years and has obtained several pioneering patents for the devices, techniques and methodology used in heat therapy.

“The issuance of this patent significantly strengthens BSD’s intellectual property and position in the marketplace for heat therapy equipment,” said Paul F. Turner, Chief Technology Officer and Sr. VP at BSD. “We are proud to be able to offer another new industry leading device to the heat therapy community. BSD has been in the forefront in developing innovative technology for heat therapy applications, and we are continuing to aggressively bolster our intellectual property. There are currently five US pending patents relating to the ablation field and six US pending patents related to the hyperthermia field. When issued, these patents will be a significant addition to the extensive intellectual property already developed by BSD.”
