The BSD-500 Hyperthermia System is used to deliver therapeutic heating (hyperthermia) using either non-invasive (external) hyperthermia, which is delivered using antennas placed over the tumor, or interstitial hyperthermia, which is delivered using antennas that are inserted into the tumor, or a combination of both.

BSD-500 has received the US Food and Drug Administration (FDA) pre-market approval (PMA).

BSD president Harold Wolcott said clinical studies have shown that hyperthermia delivered using the BSD-500 can significantly increase the effectiveness of radiation therapy without a significant increase in toxicity for certain tumors.
