OMER, Israel, April 16, 2015 (GLOBE NEWSWIRE) -- Medigus Ltd. (TASE:MDGS), a medical device company developing minimally invasive endosurgical tools and a leader in direct visualization technology, announced that results of an ex-vivo study are being revealed today at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Annual Meeting, currently taking place through April 17th at the Gaylord Opryland Hotel and Convention Center in Nashville, Tennessee. The poster presentation, entitled Endoscopic anterior fundoplication with the Medigus Ultrasonic Surgical Endostapler (MUSE): results from an ex vivo simulation trial to assess the efficacy of the procedure by comparing stapling position and gastric yield pressures, will be presented by Tae-Geun Gweon, MD, of Boston Children's Hospital, Harvard Medical School.

The aim of this trial was to identify the ideal stapling location in relation to the gastroesophageal junction (GEJ) in a validated simulation model. It evaluated the MUSE system in eight ex-vivo porcine stomachs, with stapling distances varying from 5mm to 45mm from the GEJ.  Investigators observed that procedures with a stapling distance of at least 30mm superior to the GEJ resulted in an improved lower esophageal sphincter valve mechanism measured as an increase in gastric yield pressure (GYP) in comparison to baseline. The study concluded that there should be a minimal distance of 30mm between each stapling location and the GEJ to create an efficient valve using the MUSE system.

"These trial results offer valuable insight for optimizing results and enhancing long-term patient outcomes using the MUSE system," said Chris Rowland, CEO of Medigus. "The SAGES Annual Meeting represents an important opportunity to connect with esteemed clinicians in the GI community and to provide critical updates on novel therapeutic options, such as MUSE."

MUSE offers a new treatment option for the millions of Americans who suffer from persistent gastroesophageal reflux disease, or GERD, and are unable to obtain long-term relief from available drug therapies or unwilling to undergo invasive surgical procedures. This intuitive device merges the latest breakthroughs in visualization, ultrasound and surgical stapling capabilities into a single platform, which allows a single physician or surgeon to administer the anterior partial fundoplication.

The MUSE system is FDA cleared and CE marked.


The mission of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) is to improve quality patient care through education, research, innovation and leadership, principally in gastrointestinal and endoscopic surgery. The SAGES 2015 Annual Meeting will be held at the Gaylord Opryland Hotel and Convention Center in Nashville, TN, April 15 though 17. For more information about the annual meeting visit or

About MUSE

The MUSE system is a leading technology in Natural Orifice Endoscopic Surgery procedures. The single operator system performs anterior partial fundoplication with standard surgical staples in a less invasive way, compared to other surgical procedures. Its intuitive endosurgical platform consists of a single use flexible surgical endostapler, equipped with a proprietary miniature camera, an ultrasonic sight and a range finder. The endostapler, which resembles an endoscope, is designed to be operated by a single user, includes a handle with controls, an 80cm flexible shaft, a 5cm rigid section holding a cartridge with 5 standard 4.8mm titanium surgical staples, a ratchet controlled one-way articulating section, and a distal tip. The MUSE system is FDA cleared and CE marked. Medigus anticipates that the new Category 1 Current Procedural Terminology (CPT®) code, recently created by The American Medical Association (AMA) for Esophagogastric Fundoplasty Trans-Orifice Approach procedures, would be the code used for MUSE.
