Topic Description
Motility, the movement through the digestive tract of what starts out as food, is usually taken for granted, until something goes wrong. There are a wide range of gastrointestinal (GI) disorders and dysfunctions that can be blamed on motility issues. Fifteen to twenty percent of the population suffer from symptoms of Irritable Bowel Syndrome – constipation, diarrhea, bloating and chronic abdominal pain – while 1.5 million live with the more serious Inflammatory Bowel Disease (IBD). In addition, regaining normal motility is key in the recovery from abdominal surgery, and determines feeding rates for patients on enteral feeding in the ICU.

Yet there aren’t any very good ways to measure motility of the entire GI tract noninvasively, continuously for multiple days, while under normal physiological conditions. G-Tech has developed electrode patches worn on the abdomen that read electrical signals emanating from the muscles of the stomach, small intestine and colon when they are active – driving motility – that are thin, wireless and non-invasive. The patches use Bluetooth LE to transfer raw data to a smartphone and from there on to a cloud server for analysis.

Since the previous talk in 2015 G-Tech has launched clinical trials on patients recovering from abdominal surgery at El Camino Hospital and from Whipple surgery at Stanford; together there have been nearly 100 patients tested. We have also been part of a study run by the Parkinson's Institute looking at the relationship of GI measures to Parkinson's Disease symptoms. Interesting results have been obtained in these cases and also in volunteer tests, and will be described in the talk. Additional studies are currently in negotiation and planning stages, including one on enteral feeding, two related to gastroparesis, and another looking at Crohn’s Disease patients. The logic and goals for these will be discussed as well.

Speaker Bio
Steve holds a BS in Physics from UConn and a PhD in Elementary Particle Physics from Yale. He played with technologies like particle detection and fast pulse instrumentation, sub-kelvin cryogenics, superconducting magnets, NMR and ESR, high vacuum systems and data acquisition and analysis. He remembers using Bitnet and Arpanet before there was a WWW, and sending emails to friends working at distant particle accelerators using PDP-10 and VAX terminals.

After graduation he took a postdoc position at Stanford and when that ended refused to leave the Bay Area. The next 15 years were spent at Measurex (later Honeywell) developing on-line measurement systems such as nuclear and X-ray basis weight and thickness sensors, infrared moisture sensors and large electromechanical scanning systems. In 2003 he joined Xoft Inc., a startup developing a 2mm diameter 50kV X-ray source for radiation therapy applications, and has been in the medical device field ever since. He has been CEO of G-Tech Medical since joining the company in late 2011. Steve has been in individual contributor and various levels of management roles, but has never been able to fully break away from the science and technology.
