Abstract
A unique device for long term percutaneous enteral feeding through a surgically formed stoma, such as a gastrostomy, includes a tubular member having a fluid lumen and an inflation lumen. One end of the tubular member is perpendicularly joined to a retention platform through which passes an ambient air port for the inflation lumen and an inlet for the fluid lumen. An other end of the tubular member is provided with an outlet for the fluid lumen. A one-way valve on the outlet prevents reflux of gastric contents into the fluid lumen. Disposed near the one end of the tubular member is an inflatable member, inflatable and deflatable through the inflation lumen. The inflatable member provides retention and anchoring of the device within the patient's stomach.
