SpectraScience, Inc. which formerly known as GV Medical, Inc., is a San Diego-based medical device company that designs, develops, manufactures and markets spectrophotometry systems capable of determining whether tissue is normal, pre-cancerous or cancerous without physically removing tissue from the body. The WavSTAT Optical Biopsy System offered by SpectraScience uses light to optically scan tissue and provide the physician with an immediate analysis. With FDA approval for sale in the U.S. and the CE Mark for the European Union, the WavSTAT System is the first commercially available product that incorporates this technology for clinical use. Company's LUMA imaging technology has received FDA approval as an optical non-invasive system that is proven to more effectively detect cervical cancer precursors than conventional methods available.
