New Journal Publication Demonstrates Concordance of Signals Between the G-Tech Noninvasive Patch System and Internally Implanted Electrodes

MOUNTAIN VIEW, Calif., June 29, 2022 – G-Tech Medical, a developer of non-invasive diagnostic solutions for patients with gastrointestinal disorders, today announced publication of a peer-reviewed article in the Journal of Surgical Research. Gastrointestinal Myoelectric Measurements via Simultaneous External and Internal Electrodes in Pigs presents findings from a study conducted by researchers at Stanford University in collaboration with G-Tech. The article is available online at  https://authors.elsevier.com/c/1fIjQ578XaM9Y and will appear in the Journal of Surgical Research’s November 2022 edition.

In the study researchers implanted electrodes in the stomach, small intestines and colon of Yucatan pigs and placed G-Tech patches on the pigs’ skin surface. The purpose of the study was to assess whether G-Tech’s external patch system could assess myoelectric signals and determine the organ of origin (stomach, small intestines or colon) noninvasively. The results “demonstrated a clear congruence between external and internal measurements.”

“This was an important project for us, and it was a pleasure to work with the Stanford team,” said Steve Axelrod, CEO of G-Tech. “We have previously validated our technology in studies comparing our data to antroduodenal and colonic manometry and to SmartPill data in humans. Demonstrating direct correlation between the data recorded by internal electrodes and our external electrodes in a pig model further substantiates our approach.”

The article pointed out that “Currently, there is no accurate noninvasive measurement system to diagnose gastrointestinal (GI) motility disorders.” The authors mentioned that such a system would be essential in developing neuro-stimulation treatments for motility disorders and could be used for post-operative ileus (POI) as well.

This article is the fifth peer-reviewed article covering G-Tech’s Wireless Patch System, and the first to focus primarily on technical validation. Three previous articles centered on clinical trials that demonstrated the system’s ability to detect early signals of gut function recovery following surgery, which can potentially be used to allow patients to leave the hospital earlier and reduce post-operative ileus and readmissions. Another article was a feasibility paper describing several human case studies that suggested the G-Tech system could help ambulatory patients in a variety of ways, including determining whether GI drugs are having the intended effect.

“We’re really just starting to scratch the surface in terms of the various use cases for which our system can provide real value,” said Axelrod.
