About the Company
InSight Surgical Technologies, Inc. (IST) is a clinical phase, medical technology company developing autonomous updated surgical navigation systems for digital surgery that augment the surgeon’s view of the evolving operative field to enhance surgical treatment. The company will commercialize products that provide real-time, ML/AI-enhanced, intraoperative guidance via image updating and quantitative fluorescence imaging to enable faster, less invasive, more accurate, personalized treatment of tumors and to improve the clinical outcomes of standard and robotic surgical resections.
The company was founded in October 2017 by senior members of a long-standing NIH-funded research collaboration involving faculty at Dartmouth College (including the Thayer School of Engineering, the Geisel School of Medicine and the Tuck School of Business) and University Health Network (UHN), Toronto. The company is based near Dartmouth College in Lebanon, NH, in close proximity to the nationally-recognized, tertiary-care Dartmouth Hitchcock Medical Center.
IST has a strong intellectual property portfolio and deep domain experience in both surgical navigation and quantitative fluorescence imaging technologies. The company has been awarded five separate SBIR grants (>$6.5M) to develop proprietary prototypes for these technologies. The deployment of these technologies for both low- and high-grade glioma as well as benign and metastatic tumor will significantly improve treatment outcomes relative to today’s standard-of-care surgery. IST has an exclusive license to 21 granted patents and multiple pending applications.
