Gastrointestinal Leakage

In the U.S. 1 in every 3000 people are diagnosed with some form of autoimmune disorder affecting the gastrointestinal (GI) tract. Of these patients a significant portion of them will develop further complications, either from the disease or from surgery, that result in a rupture of their GI tract allowing the contents of the stomach or intestines to leak out. This abnormal opening requires continued monitoring and treatment that can become both painful and uncomfortable. There is a need for a device that can properly and effectively manage the GI leak to alleviate the pains associated with the opening.

Controlling Abnormal Leakage from the GI Tract

An elegant device has been proposed to control the issues related to an abnormal opening in the GI tract known as an enterocutaneous fistula. The device is well suited for high output fistulas to divert the flow of the contents of the GI tract into the bowel of the patient. The device is also able to integrate fully with vacuum systems and feeding tubes for input to the gut. The device addresses the main issues surrounding the care needed for abnormal openings in the gut and effectively treats these problems.

Applications and Advantages


  • Enterocutaneous fistulas
  • Abnormal openings in gut lining


  • Device redirects flow of GI contents to bowel without need for auxiliary equipment
  • Capable of integrating with more complicated GI management systems
