    2. Optical coherence domain reflectometry guidewire

      A guidewire with optical sensing capabilities is based on a multiplexed optical coherence domain reflectometer (OCDR), which allows it to sense location, thickness, and structure of the arterial walls or other intra-cavity regions as it travels through the body during minimally invasive medical procedures. This information will be used both to direct the guidewire through the body by detecting vascular junctions and to evaluate the nearby tissue. The guidewire contains ...

    3. Ultrashort pulse high repetition rate laser system for biological tissue processing

      A method and apparatus is disclosed for fast, efficient, precise and damage-free biological tissue removal using an ultrashort pulse duration laser system operating at high pulse repetition rates. The duration of each laser pulse is on the order of about 1 fs to less than 50 ps such that energy deposition is localized in a small depth and occurs before significant hydrodynamic motion and thermal conduction, leading to collateral damage ...

  2. About Dennis Matthews

    Dennis Matthews

    Dennis Matthews is the Director of the NSF Center for Biophotonics and a professor in the Department of Neurological surgery at University of California, Davis.  CBST Director; Joint Appointment at UC Davis College of Engineering, School of Medicine and Program Leader Medical Technology Program at Lawrence Livermore National Laboratory.  Dr. Matthews is Program Leader for the Medical Technology Program at Lawrence Livermore National Laboratory as well as professor within the UC Davis Department of Applied Science and School of Medicine. He is also an Associate Director of the UC Davis Integrated Cancer Program. He directly supervises ~50 scientists, engineers, 8 graduate students, a 25 student summer intern program and 8 other support staff. Dr. Matthews is responsible for the development of industrial and medical applications of Lawrence Livermore National Lab Technology, especially for the prevention, screening, diagnosis and treatment of diseases such as diabetes, stroke, brain trauma, chronic pain and cardiovascular disease. Dr. Matthews is also responsible for founding a biomedical technology stem of research and teaching curriculum within the Department of Applied Science. Dr. Matthews leads a multi-directorate program within Livermore whose mission is to develop medical devices in collaboration with industry. Current projects and those already successfully transferred to industry include: an opto-acoustic recanalization device for treating ischemic stroke; a miniature x-ray source which is mounted on a microcatheter and used to treat coronary artery restenosis; micropower impulse radar for numerous medical diagnostics including differentiating hemorrhagic vs. ischemic stroke; an implantable, continuous glucose monitor and ultra-short-pulse laser microsurgery devices.
