As the gastroenterology device market continues to grow, here are five companies poised to take over the market in 2023.

EndoSound, Iterative Health, Medtronic, FujiFilm, and Motus GI

At the beginning of 2023, EndoSound, a newer player in the GI space, received an investment from the American Gastroenterological Association to improve its endoscopic ultrasound technology. In July 2021, EndoSound earned FDA breakthrough device designation for the device.

See Linked In post here.

Portland, OR – EndoSound®, Inc., an Oregon-based medical device innovator developing technologies that enhance access, reduce cost, and increase the safety of endoscopic ultrasound (EUS) procedures, announced that the company received an investment from the American Gastroenterological Association (AGA), AGA’s new venture capital fund, GI Opportunity Fund 1.

“AGA’s commitment to driving innovation expanded through our venture fund and we’re proud to support emerging companies, like EndoSound, that are transforming care for patients with digestive disease. Technology that can increase patient access to care and procedure safety while also lowering health care costs is truly exceptional,” said Lawrence Kosinski, MD, AGAF, AGA Governing Board Councilor for Development and Growth.


EndoSound was granted Food and Drug Administration (FDA) Breakthrough Device designation in July 2021. The EndoSound Vision System® (EVS®) is a disruptive EUS platform whose attachable transducer and supportive components transforms a conventional upper endoscope into a fully functional endoscopic ultrasound device.

EUS is an imaging technology like CT, MRI and point of care ultrasound. It is critical to the diagnosis and treatment of a variety of benign and malignant diseases particularly those of the liver, gallbladder, and the pancreas. The cost of existing systems has limited the availability of this crucial modality in the United States and around the world.

“As a practicing GI physician, the support of the AGA is an enormous validation for our mission,” says Stephen Steinberg, MD, CEO and President of EndoSound, Inc. “We were initially honored as winners of the AGA’s Tech Summit 2022 Shark Tank. This investment is an even greater testament to their belief in our team and technology. We could not be more pleased with a partner who shares similar values and a desire to provide the utmost innovative technologies to the GI community, its physicians, and their patients.” 


By eliminating the burden of cost, the EVS will provide physicians with a technological option that can enable care for their patients in a greater number of locations and settings. This brings the potential for enormous benefits to patients, payers, and providers by reducing costs in the healthcare system. The EVS is not cleared by the FDA.

“We are excited to continue to build our fund’s portfolio of early-stage, high-growth GI companies with our recent investment in Endosound, a company with technology that converts any endoscope into an endoscopic ultrasound,” said Andrea Vossler, co-founder and managing director, Varia Ventures.

PORTLAND—August 31, 2021—Endosound, Inc., an Oregon-based medical device innovator developing technologies that enhance access, reduce cost, and increase the safety of endoscopic ultrasound procedures, announced today that its EndoSound Vision System received a Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA).


The EndoSound Vision System is an add-on device that consists of a compact ultrasound beamformer, reusable transducer, and disposable mounting kit that fastens onto any flexible upper gastrointestinal (GI) video endoscope to convert it into an endoscopic ultrasound (EUS) system. Its unique distal attachment allows the endoscopist to perform advanced procedures, such as fine needle biopsy, with precision, but without the controversial elevator mechanism found on all other linear echo-endoscopes.


In recent years, multi-use endoscopes that feature an elevator mechanism have faced scrutiny due to their association with patient infection risk. In a July 2020 Safety Communication published by the FDA, it was stated that “FDA recommends health care facilities and manufacturers begin transitioning to duodenoscopes with disposable components”1 to address the challenges presented by the elevator mechanisms on these endoscopes. Major device manufacturers have consequently responded with new disposable duodenoscope models, but the similarly designed ultrasound endoscopes have been overlooked. The innovative EndoSound Vision System addresses this oversight by eliminating the need for the elevator mechanism while still maintaining the precision and imaging that is necessary for complex EUS procedures.


“The EndoSound Vision System removes significant patient safety concerns that have been connected with the elevator mechanism over the last several years,” stated Dr. Shyam S. Varadarajulu, MD, Medical Director of the Digestive Health Institute at Orlando Health.“In addition to reducing risk, the system features a disruptive price point that gives it the potential to dramatically expand the availability of this critical modality in the United States and around the world.”


“The Breakthrough Device Designation is evidence of the transformative potential the EndoSound Vision System presents,” stated Dr. Stephen Steinberg, MD, EndoSound Founder and President. “There is a clear need for a resolution to the patient safety risk presented by traditional ultrasound endoscopes. Also, for many healthcare facilities, the high cost of conventional systems creates a barrier to entry into the use of endoscopic ultrasound. With Breakthrough Device Designation, we are on an accelerated pathway to eliminating these obstacles.”


The FDA Breakthrough Device Designation expedites the development and evaluation of novel devices that offer the potential to enhance patient outcomes through more effective treatment or improved diagnosis of life-threatening conditions. Under the program, the FDA will provide EndoSound with the opportunity to provide its feedback during the pre-market phase and prioritized review of the device submission.
